1. INTRODUCTION
1.1 FOREWORD
Glassier Open Space is a midvalley gem that represents all facets of the Open Space
and Trails mission. Seasonal trail access, fishing access, habitat, agricultural lease
areas and scenic view plane protection are all components of this 282-acre area.
It is no wonder the public expressed this diversity of elements as what they love
about the open space.
The 2020 Glassier Management Plan update seeks to continue the foundation
created by the original plan, while focusing energy on areas that are ready for
additional consideration. This includes looking at irrigation efficiencies and habitat
improvements as part of a holistic plan for the site. This plan also sets forth a
process to reactivate the farmstead area and facilitate productive agricultural
operations on the property by evaluating the options for on-site housing including
the potential of rehabilitating the house.
Glassier Open Space was made possible by a strong partnership between Eagle
County, Great Outdoors Colorado, the Town of Basalt, the Mid-Valley Trails
Committee and Pitkin County. Together, these organizations invested $10.9
million in a series of acquisitions to conserve this portion of the midvalley from
development. Pitkin County Open Space and Trails (OST) strives to continue to work
with its partners for the continued success of Glassier Open Space.

Introduction | Glassier Open Space Management Plan 6
1.2 HISTORY
In the mid-Roaring Fork Valley, the valley floor
broadens into a crescent of some of the region’s
most fertile soil. It was here, in the late 1800s, that a
handful of gritty, hardworking homesteaders staked
their futures, toiling on the land rather than in the
mines of Aspen.
The town of Emma thrived as the area’s epicenter
of farming and ranching, serving as a mercantile
center and rail stop where the Denver and Rio Grande
Railroad would continue to collect produce and
livestock, bound for markets in Denver and beyond,
long after Aspen’s silver ore ceased to fill the railcars.
In fact, the productive farmlands of the midvalley
earned praise in the Aspen Times Daily in 1901. The
newspaper reported, “No more flattering tribute
could be paid to the farming industry of Pitkin County,
and especially that part of the Roaring Fork Valley
around Emma, than the statement that its farmlands
are held at a greater value per acre than any other
agricultural district in these parts.”
Chief among the valley’s exports in the first half of the
20th century was the potato – a crop farmers were
encouraged to try. On March 19, 1908, a train dubbed
the “Potato Special” pulled into Aspen, carrying state
agricultural workers who promoted potato growing
to a receptive audience and demonstrated the latest
machinery to plant, cultivate and dig potatoes.1 By
the 1930s, the valley had an established potato
culture. The Glassier family was one of many that
embraced the spud.
The family’s story began with four Glassier brothers,
all immigrants from northern Italy, who were willing
to clear rock from dirt and harness the Roaring Fork
and its tributaries to coax a living from the ground.
Fredrick H. Glassier, born in 1871, came to the
Emma area in 1891 and chose for his ranch the land
extending north and west from distinctive red cliffs
that remain a dominant feature of the landscape.2
Slicing across the red band of rock, remnants of the
Glassier ditch are still visible, a testament to Fredrick’s
tenacious, but failed attempt to bring water from
Snowmass Creek to the lower slopes of an area now
known as the Crown.3
Like many families of the era, Fredrick and his wife,
Adele (Clavel), had a large family to help run their
expanding farmlands. Married in 1904, they had six
Potato rows stretched to the base of Crown Mountain with irrigated
furrows between each row in this photo from October 1963. |

Introduction | Glassier Open Space Management Plan 8
children, five of whom lived to adulthood. Two of
them – Fredrick L. and Peter – became the second
generation to raise cattle and cultivate the fields
with potatoes, alfalfa, hay and wheat. The latter was
ground into flour at a grist mill in Glenwood Springs.4
Pigs, chickens, a few dairy cows, vegetables and fruit
trees all helped keep their family larders stocked.
Potatoes and cattle were shipped to market from the
Denver and Rio Grande siding at Hooks or Leon, both
a short distance from the ranch.5
While the elder Fredrick’s brothers ultimately
abandoned ranching, his holdings eventually
expanded to encompass some 530 acres that
stretched from the lower slopes of the Crown to the
Roaring Fork River, including a stately, brick Victorian
farmhouse that would become the center of ranch
life for Fredrick L. Glassier, his wife, Freda, and their
children. The home, of undetermined origin, was
among several substantial brick houses built in greater
Emma at the turn of the 20th century.
Planting and harvesting was done by hand and with
horse-drawn implements. Draft horses continued
to help with the labor even after Fred L. and Freda
acquired their first tractor, a Farmall, in the 1940s.6
While ranching families in the Roaring Fork Valley
were largely self-sufficient, raising potatoes was a
water- and labor-intensive operation that, for the
Glassiers and other Emma-area ranchers, relied
heavily on the Home Supply Ditch and immigrant
labor. Fifteen acres of potatoes required two weeks
to harvest. A picker earned dollar a day, Pete Glassier
recalled.7
Hispanic farm laborers helped with the back-breaking
potato harvest. In addition, area schools closed for
a week each October, excusing ranch children to
assist with their family’s harvest, while town kids
earned money by signing on with an area farmer
to sack potatoes that were then loaded into cellars
for sorting, resacking and transport to the nearest
railroad spur.8
A variety dubbed “Red McClure” thrived in the red
dirt of the Glassier Ranch, and Fred L. Glassier chose
that land at the base of the red cliffs for his half of the
farm. “The red soil was the money maker,” according
to his daughter, Joyce. In the 1950s, her father was
paid a premium for his red potatoes, she said.9

Introduction | Glassier Open Space Management Plan 10
Government subsidies and other factors made potato
growing an iffy business, however, and the enterprise
slowly gave way to the less labor-intensive enterprise
of raising hay and cattle among ranches that
remained as development pressure intensified in the
Roaring Fork Valley during the latter half of the 20th
century. One former family ranch, located across the
Roaring Fork River from the Glassier spread, lends its
name to the residential and commercial community
of Willits, a fact likely lost on many of its residents and
shoppers.
While other Emma-area lands have seen a far less
intensive transformation than the old Willits place, a
piece of the Glassier property remained in the family’s
hands for more than a century. It was on this 137-acre
parcel that Freda L. (Vasten) Glassier, feisty widow of
Fred L. Glassier, continued to keep a handful of cattle
until age 84. She died in November 2009, at age 93,
in the brick Victorian house she called home for 61
years.
The Fred L. and Freda L. Glassier property, and an
adjacent 145 acres that were formerly part of the
family’s landholdings, have been acquired by Pitkin
and Eagle counties, in partnership with the Town of
Basalt, Great Outdoors Colorado and the Mid-Valley
Trails Committee.
The acquisition of these properties created an
opportunity for modern-day agricultural use along
with recreational access to the Crown – the hills
where the Glassiers once ran cattle ¬– and the
protection of areas important to wintering elk and
deer. The initial Glassier Open Space Management
Plan, adopted in 2015, and this update to the plan,
carve out space for 21st century uses of this historic
landscape in combination with a focus on wildlife
habitat enhancements.

1.3 ACQUISITION BACKGROUND
Glassier Open Space is comprised of two Eagle County
properties, acquired in 2013 and 2014, together
totaling 282 acres.
Red Ridge Ranch, a 145-acre parcel, was purchased
in 2013 for $5 million. Its purchase conserved scenic,
agricultural, ecological and recreational resources.
Included in the acquisition was a conservation
easement on about 25 acres of the adjacent parcel
retained by the seller bordering the Roaring Fork
River, the Saltonstall River Conservation Easement.
Water rights in the Home Supply Ditch were also
conveyed as part of the purchase.
Partners in the Red Ridge Ranch purchase were:
Eagle County, contributing $2 million; Pitkin County,
$1,850,000; Great Outdoors Colorado, $600,000;
Town of Basalt, $500,000; and Mid-Valley Trails
Committee, $50,000. An intergovernmental
agreement between Pitkin and Eagle counties, and
the Town of Basalt, gave Pitkin County fee interest
in the parcel and financial responsibility for its
management, subject to conservation easements held
by Eagle County and the Town of Basalt.
In 2014, the 137-acre Glassier Ranch, bounded
on two sides by Red Ridge Ranch, was purchased
for $5.9 million. Pitkin and Eagle counties each
contributed $2,450,000; Great Outdoors Colorado
put $1,000,000 toward the acquisition. Pitkin County
holds title in fee to the parcel; Eagle County holds
a conservation easement on the property. Under
an intergovernmental agreement between the two
counties, Pitkin County manages and maintains the
property with consent/agreement from Eagle County.
The purchase, which included water rights from
the Home Supply Ditch, conserved habitat, scenery,
culturally significant buildings, agricultural and
recreational opportunities.
In a separate, but related acquisition, Pitkin County
purchased 1 acre at the corner of Hooks Lane and
Hooks Spur Road for $75,000 in 2015 in order to
provide trailhead parking for Glassier Open Space.
Late 1880s
Homesteaders move to Emma area and
begin to farm.

Introduction | Glassier Open Space Management Plan 12
Map 1. 2015 - 2020 Management Action Highlights
Much has been accomplished on Glassier Open Space
in the last five years. Some of the highlights include:
• The agricultural areas on the property were
divided into lease areas and leased to local
farmers and ranchers. Lessees have worked to
improve irrigation infrastructure, added hoop
houses to extend the growing season, and
improved some of the existing structures.
• A headgate to measure and allocate water
throughout the property was installed along the
Home Supply Ditch.
• Two user-separated singletrack trails were
designed and built in addition to the access
route through the active agricultural lease areas,
opening for public use in 2016. The trails are
closed to dogs and motorized users and have a
seasonal closure to protect wintering wildlife.
• River access for non-commercial fishing was
opened to the public, though the route to get
there has seen little use.
• The Hooks Spur parking area was acquired and
constructed.

square feet to be used as a residence or facility that
complements the operations of the property on the
area near Hooks Spur Road.
2.2.2 GLASSIER RANCH
The Fred L. and Freda L. Glassier Ranch is 137 acres.
Glassier Ranch includes approximately 100 acres of
fertile, irrigated fields and nine acres on the Roaring
Fork River. The parcel also encompasses an historic
farmhouse and numerous outbuildings on the nine
acres adjacent to the river. Pitkin County is the owner
of the property and Eagle County holds a conservation
easement on it, protecting the agricultural, ecological,
scenic, recreational and open space conservation
values of the land (Pitkin County Reception No.
607109).
The full responsibilities and requirements of the
easements can be found in the recorded documents,
however, a few of the relevant highlights are
summarized here. Both easements allow for the
county to lease the property and water rights for
agricultural operations, including grazing and raising
of horses and livestock, and the cultivation of crops
and other agricultural activities that are consistent
with protection of the long-term ecological viability
of the land. Subdivision of the property is prohibited.
Non-motorized recreational trails are permitted along
with appropriate trail amenities. The easement also
requires that the management plan to be reviewed
at least every five years and amended if determined
necessary by either owner.
On the Glassier Ranch property, residential use of
the existing home is permitted (with a certificate
of occupancy), as is its repair or replacement. The
easement also established a 5-acre building envelope
in which new improvements may include a residence
or facility of up to 2,000 square feet to complement
the permitted uses on the property, and a greenhouse
of up to 5,000 square feet.
2. EXISTING CONDITIONS
2.1 LOCATION AND LAND USE CONTEXT
Glassier Open Space is located in the rural,
agricultural area of Emma in Eagle County, just
outside of Pitkin County. The predominant land uses
are grazing and hay production as well as estate-sized
residential lots separated by the Roaring Fork River
from the growing commercial center of El Jebel/
Willits Town Center. The population of the midvalley
is growing, with projects in Willits and the approved
Tree Farm Planned Unit Development, where an
additional 340 homes and 135,000 square feet of
commercial development was approved in 2019.
Glassier is part of a corridor of protected agricultural
lands bracketed by the Grange Ranch and Emma Open
Space upstream and Rock Bottom Ranch downstream.
Other protected lands in this area include Crown
Mountain Ranch, Happy Day Ranch, Emma Farms and
Shippee Open Space. The property is adjacent to and
provides non-motorized access to Bureau of Land
Management (BLM) acreage known as the Crown.
Together the private conservation easements, open
space properties and federal lands contribute to a
contiguous, expansive protected landscape within the
midvalley totaling over 10,000 acres.
2.2 PROPERTIES AND EASEMENTS
Glassier Open Space was acquired as two separate
properties in 2013 and 2014 – Red Ridge Ranch and
Glassier Ranch, respectively – which are protected by
conservation easements that permanently protect its
agricultural, ecological, scenic, recreational and open
space values. The 282-acre open space is located off
Hooks Spur Road, approximately two miles from State
Highway 82 with the regional multi-use Rio Grande
Trail passing through the property.
2.2.1. RED RIDGE RANCH
Red Ridge Ranch is 145 acres. The property includes
50 acres of irrigated fields and 95 acres on the
flanks of the Crown. Pitkin County is the owner
of the property, while a conservation easement
encumbering the property is held jointly by the
Town of Basalt and Eagle County in order to ensure
the protection of the agricultural, ecological, scenic,
recreational and open space values of the land (Pitkin
County Reception No. 601973). The easement allows
for the construction of a structure of up to 2,000

2.2.3 AGRICULTURAL ACCESS AGREEMENTS
Two different access agreements allow neighboring
agricultural producers, who hold grazing permits on
the BLM, to access the Crown through Glassier Open
Space:
1. Red Ridge Ranch Grazing Access Easement -
This easement was recorded when Pitkin County
purchased the Red Ridge Ranch property and allows
the neighboring agricultural producer/holder of
the BLM grazing permit to access the Crown for
"cattle moving and herding purposes only." It allows
motorized access, limited to 4-stroke engines. There is
no date restriction on when the easement holder can
use the access. The easement is active as long as the
grazing permit on the BLM continues. The easement
was recorded on January 29, 2013, at Reception No.
201301857 in the property records of Eagle County.
2. Emma Farms Revocable Access License - This
license was recorded when Pitkin County purchased
Fred L. and Freda L. Glassier Ranch and allows the
neighboring property owner/BLM lease holder
(currently Emma Farms) to access the Crown from
March 21 to Dec. 21 for "monitoring cattle and related
agricultural purposes only." It allows pedestrian,
equestrian and motorized access (limited to 4-stroke
engines) to the ranch road connecting to BLM lands.
Emma Farms must give 10-day notice to the county
if they plan to move cattle through the open space.
The term of the license is valid as long as Emma Farms
or a subsequent owner complies with the license
and has a BLM grazing permit. The easement was
recorded on July 15, 2014, at Reception No. 611813 in
the property records of Pitkin County.
2.2.4 NEIGHBORING PROPERTY EASEMENTS AND AGREEMENTS
1. Emma Farms Trail Easement - A trail easement was
obtained from Emma Farms, the adjacent neighbor
to the south, to connect a public, non-motorized,
soft-surface trail from Nancy’s Path to Glassier Open
Space. The easement has been recorded but not
activated.
2. Saltonstall River Conservation Easement - Along
with the purchase of Red Ridge Ranch, Pitkin County
and Eagle County acquired a 46-acre conservation
easement on property retained by the seller along the
Roaring Fork River. This property is not open to the
public and protects the riparian habitat and river.
2.3 PROPERTY ACCESS AND PARKING
In order to limit the number of vehicles on Hooks Spur
Road, no public parking is available on Glassier Open
Space. In 2015, OST worked with property owners at
the corner of Hooks Spur Road and Hooks Lane on an
open space subdivision exemption to purchase one
acre of their property for a parking area, which was
constructed in 2017. The parking area is located 0.5
miles from Glassier Open Space provides three (3)
trailer parking spaces for equestrians and 28 regular
parking spaces. Additional spaces for users of the Rio
Grande Trail are provided by RFTA adjacent to the

2.4 EXISTING PLANS AND POLICIES
There are many partners, jurisdictions and regional
considerations that factor into the management of
this open space property.
2.4.1 EAGLE COUNTY ZONING
The property is zoned Resource by Eagle County,
Colorado. According to Article 3 in the Eagle County
Zone Districts:
The purpose of the Resource (R) zone district is to
maintain the open rural character of Eagle County
and to protect and enhance the appropriate use of
natural resources and agricultural uses in the county,
including water, minerals, fiber and open land. This is
accomplished by limiting residential development to
very low-density, single-family uses on lots of 35 acres
or larger, or by encouraging clustered development on
smaller lots within those portions of a property that
do not contain environmental resources or natural
hazard areas and by maintaining the remainder of the
property as common open space or ranch land, and
by limiting new commercial development to uses that
have a resource orientation and to small recreation
areas that comply with Master Plan policies.
2.4.2 ROARING FORK WATERSHED PLAN (2012)
The Roaring Fork Watershed Plan establishes
goals and recommendations in regional water
management, surface water, groundwater, water
quality, and riparian and stream habitat. The
acquisition of Glassier Open Space advanced several
of the recommended actions in this plan related to
water conservation, noxious weed control, riparian
protection, education, research and partnerships.
Looking forward, opportunities exist to further
advance work in all these realms, most notably in the
protection and restoration of riparian areas and water
conservation measures. The Watershed Plan’s action
item to work with landowners, resource experts
and others to “plan and Implement key riparian and
instream protection and restoration projects” is
classified as urgent.
2.4.3 RFTA RULES AND REGULATIONS FOR THE RIO GRANDE TRAIL
The multi-use Rio Grande Trail, managed by the
Roaring Fork Transportation Authority (RFTA), runs
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Glassier Open Space Management Plan | Existing Conditions 17
its Resource Management Plan (RMP) after multiple
years of outreach and planning. The RMP designated
the Crown’s 9,100 acres as a Special Recreation
Management Area (SRMA) with an emphasis on
day-use recreation and mountain biking. Although
managed primarily for mountain biking, the area has
trails open to hikers, equestrians and motorized use;
it also supports grazing permits for cattle, and wildlife
habitat protection. To protect wintering big game and
other wildlife, the Crown is closed to motorized and
mechanized travel seasonally from Dec. 1st through
April 15th. Extended winter closures are allowed
under severe winter conditions at the request of CPW.
Over the last five years, the BLM has partnered with
the Roaring Fork Mountain Bike Association (RFMBA)
to undertake trail and signage projects and refine the
Travel Management Plan for the area. Trail projects
on the eastern or Highway 82 side of the Crown
included the Buckhorn Traverse and Buckhorn Trails,
the Vasten Trail, and connections to the Prince Creek
side of the Crown (a total of approximately 12 miles
of new mountain bike singletrack). In addition to the
focus on mountain biking, about 10 miles of double-
track previously designated for mountain biking has
been converted to foot and horse trails connecting
the existing Glassier foot and horse trail to Nancy’s
Path, with additional routes and trails rehabilitated
or designated for administrative uses. With the BLM
trails, there are multiple route options and lengths
that include the two Glassier trails.
2.4.7 OPEN SPACE AND TRAILS POLICIES
OST Mission and Article 13
The OST Mission and Article XIII of the Pitkin
County Home Rule Charter define the purposes
of the program and how the Open Space fund can
be used. The overarching mission of the Pitkin
County Open Space and Trails Board of Trustees is
to acquire, preserve, maintain and manage open
space properties for multiple purposes including,
but not limited to, recreational, wildlife, agricultural,
scenic and access purposes; and to acquire, preserve,
develop, maintain and manage trails for similar
purposes.
Article XIII further details the roles and responsibilities
of the OST program. In regard to historic properties
such as the Glassier House, Article XIII supports
through the property and is governed by their rules
and regulations and enforced by RFTA staff and the
Eagle County Sheriff. The Rio Grande Trail to the north
of Glassier Open Space is subject to a winter closure
from Nov. 30th through April 30th; however, the
southeastern-most gate opens on April 15th of each
year to coordinate with the BLM's opening date and
ensure that trail users don't accidentally get stuck
inside the closed section of the Rio Grande Trail. The
gate just downvalley of the Buckhorn Trail remains
closed through April 30th.
2.4.4 MID-VALLEY TRAILS PLAN (2020)
The 2020 Mid-Valley Trails Plan was adopted by
Roaring Fork Valley Regional Planning Commission of
Eagle County on Sept. 3rd, 2020. Although the plan
does not directly address Glassier Open Space, it does
speak to the need for trail connectors in the vicinity.
The two most applicable include the desire for a trail
connection between Crown Mountain Park and the
Rio Grande Trail and an improved/new trail bridge at
Hooks Lane.
2.4.5 MID-VALLEY AREA COMMUNITY PLAN (2018)
The Mid-valley Area Community Plan is the sub-area
plan for the larger Eagle County Comprehensive
Plan, which is adopted by the Roaring Fork Valley
Regional Planning Commission appointed by the
Eagle County Board of County Commissioners.
The current Mid-valley plan was adopted in 2018
and identifies goals and strategies to support four
different “character areas” within the midvalley.
Glassier is within the Emma Character Area, where
continued agricultural uses and a focus on local food
production and preserving the rural character of
the area are central goals. The plan also supports
protecting and enhancing wildlife habitat and natural
resources, preserving historic buildings and sites, the
conservation of water and protection of water rights,
and other goals that are closely aligned with the open
space values provided by Glassier Open Space.
2.4.6 THE CROWN SPECIAL RECREATION MANAGEMENT AREA (2015)
Glassier Open Space provides public access to the
Bureau of Land Management’s (BLM) Crown Special
Recreation Management Area (SMRA). In 2015, the
BLM’s Colorado River Valley Field Office approved
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Existing Conditions | Glassier Open Space Management Plan 18
preserving cultural, historic and archaeological
resources located within properties that are
otherwise acquired for their customary open
space characteristics. There are parameters on
how much Open Space funding can be used on
historic preservation and how the fund can be
used to support the reuse of historic buildings.
These parameters are outlined in the 2018 Historic
Structures Policy. Uses or improvements to buildings
that do not meet the purposes stated in the charter
and that are outside of the Open Space and Trails
mission are allowed, but they need other funding
sources.
Protection of Natural Biodiversity and
Management of Human Use Policy (2016)
This Open Space Board policy requires that human
uses on OST properties are managed in a manner
that preserves and protects native biodiversity. The
OST program seeks to rely on the best available
science to guide management decisions, inform
specialized habitat management needs, and identify
opportunities to restore healthy, natural functions
in degraded habitats. Spatial or temporal closures or
other appropriate mitigation strategies are supported
to protect sensitive habitats from recreational or
agricultural impacts.
OST Agricultural Lease Bid Process / Policy
The OST Board adopted the Agricultural Lease Bid
Process (the “Process”) on Oct. 7, 2014. The Process
was developed to create a more competitive and
transparent leasing process that also was compliant
with the overall Pitkin County Procurement Code.
Since the introduction of the agricultural lease bid
process, interest in land leasing has increased. OST-
leased land now totals approximately 398 acres,
up from 240 acres at the advent of the lease bid
process, with individual lease areas ranging from
10 acres to 100 acres. In response to this increase
in properties and an increased interest in leasing
from Pitkin County, OST updated the Open Space
Lease Bid Process and Policy (Policy) on Sept. 21,
2017, to recognize the needs of beginning farmers
and ranchers, and to protect the ability of all
producers to provide local, natural and organic food
for the community. In addition, the policy describes
evaluation criteria to assist staff in selecting the most
appropriate lessee, process steps and increased
oversight measures to ensure the proper stewardship
of the agricultural lease areas. The full policy is
included as Appendix D.
OST Historic Preservation Policy
The Open Space Historic Preservation Policy was
adopted by the Open Space Board on Nov. 1, 2018
to guide expenditure of funds on historic assets
(included as Appendix C). The policy outlines four
management options for historic structures on
OST properties including: removing the structure;
allowing nature to take its course; actively stabilizing
the structure with exterior restoration to historic
standards; or, preserve the structure for continued
use. The policy also establishes the amount of money
within the OST fund that can be spent on historic
structures, on all open space properties, over the life
of the fund at 2% of the annual revenue between
2017 and 2040. Spending in an individual year may
exceed the 2% target as long as the 20-year average
complies with the policy. Grants, gifts and other
outside funding sources can complement outlays from
the Open Space fund.
Title 12 – Open Space and Trails Policies
The parcels that are the subject of this plan are
governed by Title 12 – the Open Space and Trails
section of the Pitkin County Code. Title 12 outlines
the rules, regulations and management of the
county’s open space and trails properties. Title 12
establishes the authority for the Open Space and
Trails Board to adopt individualized management
plans for specific Open Space and Trails properties.
If the restrictions differ from what is included in Title
12, the plan must be adopted by the Board of County
Commissioners.
Intergovernmental Agreement Between
Pitkin and Eagle Counties
In 2015, the Eagle County and Pitkin County
Boards of County Commissioners approved an
intergovernmental agreement enabling the
applicability and enforcement of Pitkin County's Title
12 rules and regulations on Glassier Open Space,
Emma Farms Conservation and Trail Easement and at
the Glassier Trailhead (Hooks Spur parking area).

2.5 NATURAL RESOURCES
2.5.1 INTRODUCTION
While most of the acreage at Glassier Open Space is currently dedicated to
agriculture production, the property also has noteworthy ecological value and
potential. The Glassier Open Space conserves important riparian and upland habitat
in the midvalley, provides landscape connectivity for wildlife between the Crown
and the Roaring Fork River and provides ecosystem services such as precipitation
absorption, water storage and soil conservation. Wildlife such as deer and elk benefit
from the seasonal closure of the property to public use as they have come to rely on
agricultural fields near the valley floor during the winter months and as transitional
habitat.
Outside of the agricultural lease areas, there are two distinct ecosystems
represented on Glassier Open Space. A wetland/riparian woodland plant zone exists
along the bank of the Roaring Fork River and along the Home Supply Ditch. The
hillsides that rise steeply above the pastures to the Crown host a mosaic of upland
plant communities. There is a small strip of sagebrush shrubland located in the
transition zone between the steep slopes and hayfields.

2.5.2 WATER AND WETLANDS
The Roaring Fork River flows from east to west along
the northern edge of Glassier Open Space, and
supports an undeveloped riparian area nearly five
acres in size.
Water Quality and Quantity
Information on water quality, quantity or aquatic
life has not been collected directly on site, but half
a mile upstream of the property, near Hooks Bridge,
is a sampling site for water quality and aquatic life
(conducted by River Watch of Colorado and Roaring
Fork Conservancy) and streamflow (operated by
USGS). The results of a 2011 macroinvertebrate
survey found that pH, temperature, and
macroinvertebrate communities indicate there are
healthy aquatic conditions in this reach of the Roaring
Fork River.1
The Colorado Water Conservation Board holds an
instream flow right for this stretch of river (75 cfs
from 10/1-3/31, and 145cfs from 4/1-9/30), which
is met year-round. Streamflows, monitored just
upstream of the property by the USGS, are influenced
by operations at Ruedi Reservoir and Dam that
release flows into the Fryingpan River, upstream of
Glassier Open Space, and several diversion ditches.
Real-time and historical data are available at https://
waterdata.usgs.gov/nwis/uv?site_no=09081000.
NATURAL RESOURCE STUDIES AND DATA
Baseline ecological conditions were assessed in 2012-13 by Andrea Tupy of Pine Brook Ecological to
document the natural resource conditions and conservation values of both the Glassier Ranch and Red
Ridge Ranch parcels for the conservation easements conveyed. These assessments of habitat types and
general conditions are available via these links:
• Baseline Conditions Report - Glassier Ranch (2013)
• Baseline Conditions Report - Red Ridge Ranch (2012)
Regional studies and resources that provide additional information covering the Glassier property
include:
• Colorado Parks and Wildlife Species Activity Maps (2015)
• State of the Watershed Report (2008)
• A Review of Aquatic Life and Stream Health in the Roaring Fork Watershed (2012)
• USDA Web Soil Survey (report run in 2013)
• USGS Stream Gage near Emma

Existing Conditions | Glassier Open Space Management Plan 22
Instream and Riverbank Health
The Roaring Fork Stream Health Initiative (2007)
states that small, isolated patches of native riparian
habitat remain in this reach, some of which occur at
Glassier. Instream habitat is generally degraded in
this midvalley area from sedimentation and nutrient
loads. The river channel and both right and left banks
were classified as Heavily Modified in the 2007 report,
due to the impacts on native riparian habitats from
agriculture, recreation and development. River health
is not controlled or measurable at a single, defined
section, and no specific studies have been completed
on the Roaring Fork River specifically within the
bounds of the property.
Wetlands and Riparian Areas
Most of the area between the river and farmstead
sits on a floodplain bench and is riparian in nature.
Portions of this area are seasonally saturated, though
this hydrology may be controlled by subsurface flows
from flood irrigation activities elsewhere. No formal
groundwater studies have been done to assess source
and/or direction of the water here. Wetland areas
have not been formally delineated to determine if
they are considered jurisdictional wetlands protected
by the federal government. However, the vegetation
present provides some information on underlying
hydrologic conditions. Vegetation conditions are
presented in Section 2.5.4.
AGCI's soil moisture monitoring data from the Glassier riparian zone shows the likely influence of flood irrigation on the agricultural fields. The irrigation begins in June and is held by the soils through the beginning of winter, when the water level slowly goes back down. | Source: AGCI
Figure 2. Glassier Ranch Average Daily Soil Moisture at 20 inch Depth.
2.5.3 SOILS
Data available from the NRCS USDA Web Soil Survey
provide general information about the types of
soils present on the property, though actual soil
characteristics can vary greatly within short distances.
Thirteen soil types occur on the property, details
on which can be found in the Baseline Conditions
Reports. The agricultural areas are characterized by
loam to sandy loam soils, while the steeper uplands
are more cobbly loam soil and exposed bedrock.
Partially hydric soils, those sometimes saturated
with water, exist along the bank of the river at the
northern edge of the property. Soil samples were
collected and tested at three locations within the
agricultural lease areas in 2015, see Section 2.5
Agricultural Use.
Aspen Global Change Institute (AGCI) operates and
maintains one soil moisture monitoring station on
the property as part of their iRON network that tracks
soil moisture, air temperature and precipitation
across an elevational gradient in the Roaring Fork
Valley. Soil moisture is monitored at 2-inch, 8-inch,
20-inch and 40-inch depths. Currently, the station is
located in the riparian zone near the homestead and
has been used in AGCI’s educational programs with
Basalt High School students. Data shows that soil
moisture levels are elevated consistently from early
June through November, indicating that the hydrology
in this location is controlled by irrigation activities.

2.5.4 VEGETATION
Plant communities are one of the most useful indicators
of natural resource conditions as the species present
are a result of the unique combination of geology, water
availability, climate, sunlight and human activity in a
given location. Four plant communities are found on the
property along with agricultural grasslands or irrigated
meadow: Colorado Plateau piñon-juniper woodland,
Rocky Mountain Gambel oak mixed montane shrubland,
intermountain basins sagebrush community and Rocky
Mountain lower montane riparian woodland/shrubland.
The first three are all upland plant communities and are
interspersed in a mosaic on the landscape.
Upland Plant Communities
The hillsides and rocky slopes that rise up from the fields
to connect to the Crown are characterized by a mosaic
of plant communities all well adapted to dry conditions,
rocky soils and strong sunlight. The three communities
(more simply referred to as piñon-juniper, Gambel oak
and sagebrush) are distinguished by the dominant plant
species and associated understory. These are described
separately in detail below, though it is together that they
comprise the upland portion of the property and offer
forage, cover, breeding, nesting and movement corridors
to a variety of wildlife.
Colorado Plateau Piñon-Juniper Woodland
Pockets of piñon-juniper woodland occur on the
slopes on the Crown, interspersed with shrubland
communities. Juniper and pinon trees dominate the
overstory, with many shrub species, including sagebrush,
Gambel oak and serviceberry, with some mountain
mahogany, snowberry and antelope bitterbrush. This

community has a sparse, rocky understory consisting
of mostly native grasses. Last surveyed in 2012, this
vegetation community was largely intact and in good
condition, with few non-natives or noxious weeds.
Rocky Mountain Gambel Oak-Mixed Montane Shrubland
With a patchy distribution across the property,
this plant community varies a bit, but typically has
short shrubs in the understory of the dominant
Gambel oak. Shrubs that co-occur include antelope
bitterbrush, serviceberry, sagebrush, mountain
mahogany, chokecherry, Woods’ rose and snowberry.
The herbaceous layer is sparse to somewhat dense
with many native grasses and low forb coverage.
Signs of heavy browsing exist, but overall this plant
community is in good condition throughout the
property. In the upper portions of the property much
of the Gambel oak has reached maturity.
Intermountain Basins Sagebrush Community
Sagebrush shrublands occur on the property
throughout the upland areas. Bare soil is common but
secondary shrubs occur sporadically throughout, and
native grasses and forbs are numerous. The sagebrush
ecosystem is targeted for conservation by Colorado
Parks and Wildlife and others, as its extent across
the Western U.S. is rapidly declining from habitat
fragmentation and degradation.
Riparian Plant Community
Rocky Mountain Lower Montane Riparian
Woodland / Shrubland
The primary riparian plant community parallels
the Roaring Fork River on the northern part of the
property. It is defined by the Colorado Vegetation
Classification Project (CVCP) and NaturServe as “Rocky
A diversity of riparian zones is present on the property, with cattail and reed canarygrass wetlands (left), cottonwood and reed canarygrass along the ditch above the pasture lands (middle), and the downstream riparian area (right).
Mountain lower montane riparian woodland and
shrubland.” This riparian area has a relatively dense
overstory dominated by narrowleaf cottonwood and
boxelder with a dense shrub understory of willow,
alder, dogwood, riverbirch, chokecherry and sumac.
Dense grasses cover the ground, including reed
canarygrass. Additional riparian areas, dominated
by willow and cottonwood, that are found along
the Home Supply Ditch are healthy, but with many
weeds present. These riparian areas provide breeding
habitat for songbirds and small mammals and foraging
habitat or cover for human-tolerant large mammals.
A low wetland area exists in the northeast corner
of the property with standing water saturating the
ground during irrigation season. Wetland plant
species that always, or nearly always, occur in
saturated soils such as willows, cattails and sedges
were noted here in the 2012 baseline conditions
assessment. Reed canarygrass also occurs in much of
this wet, low-lying area.
Threatened, Endangered and Rare Plants
No threatened or endangered plant species are
known to occur on the property. However, a nearby
area on BLM land hosts an excellent occurrence of the
globally rare Harrington’s beardtongue (Penstemon
harringtonii). Harrington’s beardtongue is endemic to
Colorado and grows almost exclusively in sagebrush
communities.

Noxious Weeds
Invasive weeds occur across the property, in the
agricultural area, along trails and ditches and
particularly around the farmstead and northern
portion of the property. Grazing and other
disturbances have furthered the spread of invasive
species on the property. Noxious weed species
observed on the property include but are not
limited to plumeless thistle, Canada thistle, scentless
chamomile, common tansy and houndstongue.
These are on the Colorado List B of noxious weeds,
those slated for suppression, and have been treated
by Open Space and Trails outside of agricultural
lease areas annually. Agricultural lease holders are
responsible for treating Colorado List A and B species
within their lease areas.
There are concentrated areas of cheatgrass in the
agricultural pastures and reed canarygrass along
ditches and in the riparian zone, both of which are of
little value to most wildlife species. Cheatgrass and
reed canarygrass do occur on many OST properties
and the program is beginning to look at various
methods to control these invasive plants.
Agricultural Grasslands
Over half the property is considered agricultural.
Common pasture plants exist in the meadows,
including smooth brome, Timothy grass, wheat
grasses and alfalfa, with pockets of Gambel oak
and willow scattered throughout. See Section 2.5,
Agricultural Use, for more information.
Other: Residential Areas and Travel Corridors
Various other shrub and tree species occur
scattered across the property – along trails, roads,
old ditches and in fields and garden areas near the
homestead. These trees and shrubs include aspen,
narrowleaf cottonwood, spruce, Gambel oak,
willow, chokecherry, plum, cherry, Woods’ rose and
dogwood. The majority of these scattered plants
are hedged, meaning they are altered in form from
significant browsing. Non-native and invasive plant
species are common throughout.

Glassier Open Space Management Plan | Existing Conditions 27
2.5.5 WILDLIFE
Glassier Open Space consists of native upland
habitat, a small riparian area and agricultural fields.
The variety of these habitats supports diverse life,
at different times of the year. Taken together, the
natural and human-altered areas here provide
important habitat for many species, from insects to
large mammals, and meet needs such as forage, nest
sites, water, movement corridor, breeding areas and
cover. The Glassier property is small in comparison to
the adjacent BLM Crown area, which offers extensive
acreage of protected, contiguous upland habitat. The
wildlife that use Glassier Open Space rely heavily on
these adjacent, federally managed lands.
Mammals and Game Species
Colorado Parks and Wildlife maps are used to identify
the species that may occur on the property. From
baseline reports, more than 40 mammal species
are suspected to occur here, many non-game
species have been observed, and several owl and
bat species may occur on the property, as well.
OST has been monitoring wildlife on Glassier Open
Space using cameras placed at two locations along
the existing trails. Camera data shows year-round
use of Glassier by mule deer. Elk sightings typically
begin in November and dwindle in April. The largest
concentrations of elk often appear in December and

SPECIES ACTIVITY
MAPPING:
Colorado Parks and Wildlife (CPW) provides
information on wildlife distributions
for environmental assessment, land
management, resource planning and general
scientific reference. While acknowledging
that animal distributions are fluid and
populations and their habitats are dynamic,
this data, as well as site observations and
activity counts, provide important information
to understand how the land is used by
wildlife.
Complete definitions of each habitat area can
be found here:
https://cpw.state.co.us/learn/Maps/
CPW-Public-GIS-Species-Activities-
Definitions.pdf
WINTER RANGE: Part of the overall
range where 90% of the individuals
are located from the first heavy
snowfall to spring green-up (based
on an average of the last five out of
ten winters.
WINTER CONCENTRATION AREA:
The part of the winter range of elk
where densities are at least 200%
greater than the surrounding winter
range density during the average
five out of ten winters from the first
heavy snowfall to spring green-up.
SEVERE WINTER RANGE: The
part of the range where 90% of the
individuals are located when the
annual snowpack is at its maximum
and/or temperatures are at a
minimum (based on the two worst
winters out of ten).
HIGHWAY CROSSING: Areas
where elk or deer traditionally cross
roads, presenting potential conflicts
between elk/deer and motorists.
MIGRATION CORRIDOR: A specific
site through which large numbers of
animals migrate and loss of which
would change migration routes.
SUMMER RANGE: The part of
the overall range where 90% of
the animals are located between
spring green-up and the first heavy
snowfall. In some areas winter range
and summer range may overlap.

OVERALL RANGE:
Glassier Open Space falls within the identified
“Overall Range” for a number of other wildlife
species including wild turkey, river otter, common
sagebrush lizard, plateau fence lizard, bullsnake,
smooth greensnake and terrestrial gartersnake,
and is mapped as “Foraging Area” for great blue
heron, osprey and bald eagle.
As the midvalley becomes more developed,
mountain lion and black bear habitat diminishes,
resulting in these species more frequently roaming
into developed areas. Conservation of the native
habitat on Glassier Open Space will help sustain
natural foraging areas for black bear and mountain
lions, hopefully reducing the need for these
species to roam into nearby neighborhoods, and
thus lessening the probability of negative human
interactions.
FALL CONCENTRATION AREA: The
portion of overall range occupied from
Aug. 15 until Sept. 30 for the purpose
of ingesting large quantities of nuts and
berries to establish fat reserves for winter
hibernation.
HUMAN/BEAR CONFLICT AREA: A
portion of overall range where two or
more confirmed black bear complaints
per season were received resulting in
CPW investigation, damage to persons
or property, and/or the removal of the
problem bear(s). Does not include damage
caused by bears to livestock.

January. Elk are occasionally seen during the summer
months, as well. Sporadic sightings of mountain lion,
bobcat, black bear, coyote, fox, rabbit and skunk have
also been recorded.
Game species that occur on the property include
black bear, mountain lion, wild turkey, mule deer
and elk. Glassier is mapped as “overall range” for
mountain lions, turkeys and bears, with the latter also
having “fall concentration” habitat on the property.
Mule deer and elk are of particular interest to the
public and are emphasized here (see Map 5). Both
rely on space near the valley floor during the winter
months and as transitional habitat. Both ungulate
species have “overall range,” “winter range” and
“winter concentration area” mapped on the property.
Deer also have “summer range,” “severe winter
range” and “critical winter range” mapped, the last
of which is mapped about a mile away for elk. The
property is currently closed to public use seasonally
from Dec. 1st through May 15th to benefit all local
wildlife, but especially these species. Heavy use by
these species has been observed here, and very few
violations of the closures occur each year. During the
summer months, when these mammals don’t rely
heavily on this portion of their broader landscape,
the land shifts to use for agriculture and trail use is
permitted.
Birds
The interspersed plant communities at Glassier Open
Space offer nesting, foraging and migrating bird
habitat, and nearly 100 bird species are suspected to
occur here. There have been no concerns warranting
focused avian surveys to date on the Glassier
property.2 Songbirds associated with montane
shrublands, sagebrush and riparian woodlands are
common. Raptors such as red-tailed hawks, Cooper’s
hawks, kestrels, eagles and harriers hunt and live on
the property. Ospreys have nests within several miles
of the property and presumably forage in the river
here.

Wildlife and Agriculture
The agricultural lease areas, though far from native
plant communities, provide valuable habitat to a
variety of species. Irrigated fields offer high-quality
transitional forage to ungulates in late fall/early
winter and again in the spring. This transitional
habitat is becoming increasingly important to
the survival of local deer and elk populations as
development in the valley floor continues.
The fields provide habitat for other species, including
ground-nesting birds, pollinators, frogs, waterfowl,
hawks and other birds, small mammals and insects.
Specifically, the alfalfa in the fields benefits pollinators
and other insects, which then serve as prey base for
many birds. Portions of the hayfield that accumulate
standing water during irrigation season offer a unique
habitat. Western chorus frogs, other amphibians,
many species of waterfowl, and even sandhill cranes
have been observed utilizing the flooded fields.
Herpetofauna and Fish
Six species of reptiles and amphibians likely occur on
the property. Appropriate habitat currently exists for
bullsnakes, Plateau fence lizard, sagebrush lizards,
smooth green snake, tiger salamanders, western
chorus frogs and western terrestrial garter snakes.3
The fishery is characterized by sportfish including
brown trout, rainbow trout and, to a lesser extent,
mountain whitefish. Native species that may occur
are cutthroat trout, and bluehead and flannelmouth
suckers. Native minnows are likely to occur, including
the speckled dace and sculpin. Non-native, invasive
white and longnose suckers are present, as well.4
Endangered, Threatened or Rare Wildlife
Of the wildlife species known or likely to occur on the
property, three species – bald eagle, river otter and
Townsend’s big-eared bat – are listed as threatened or
species of concern.

2.6 AGRICULTURAL USES
2.6.1 EXISTING LEASE AREAS
The 2015 Glassier Open Space Management Plan
identified six (6) lease areas. During the drafting of the
2015 plan, there was a desire by the public to make
small acreage areas available for new and beginning
farmers while maintaining the larger fields for hay
production and cattle grazing. For irrigation, 6.8 cubic
feet per second (cfs) of water from the Home Supply
Ditch is available to be used across the various lease
areas. The Natural Resource Conservation Service
(NRCS) was consulted to develop a water measuring
and splitting system. Constructed in 2015, the
diversion structure allows water users to measure and
split water to the lease areas.
• Lease A consists of 44.5 acres of irrigated hay
meadow. The lease area has 2.45 cfs of water and
is flood irrigated. The lessee currently grows and
cuts hay and has grazed sheep in previous years.
No improvements have been made to the lease
area aside from general ditch maintenance.
• Lease B consists of 92.4 acres of irrigated hay
meadow. The lease area has 4.0 cfs of water
and is flood irrigated. The lessee currently grows
and cuts hay and grazes cattle in the fall. Flood
irrigation does not cover the entire lease area
due to topography. No improvements have been
made to the lease area aside from general ditch
maintenance.
• Lease C consists of 10.3 acres. Prior to the
Pitkin County purchase, the area was used for
equipment and vehicle storage. Portions of the
lease area do get irrigated from sub-irrigation and
surface water that leaks out of lateral ditches.
Lease C was only utilized for periodic grazing and
no substantial improvements were made over the
past 5 years.
• Lease D consists of 3.5 acres of grass pasture.
No water is associated with the lease but
tailwater from both lease A and lease B reach
the area. Early on in the lease, the lessee did
some plantings but they did not survive due to
groundwater saturation. The only agricultural use
on Lease D has been fall grazing.
• Lease E consists of 0.6 acres of cultivated
land currently used for vegetable and flower
production. The lease area has 0.1 cfs of water
Tailwater running along an agricultural field.
Cattle graze in the fields.
and the lessee recently installed a water tank
to capture water and pump out for sprinkler
irrigation. In addition, Pitkin County installed a
cistern, which is filled by a ditch, and utilities
access for installation of a pump; however, this
has not been pursued for irrigation. A small hoop
house structure was built as part of an Eagle
County Agricultural Extension workshop and
an additional high tunnel was recently built to
support the lessee’s operation. The hoop house
and high tunnel are considered temporary and
must be removed when the lease expires or is
terminated. The lessee also utilizes the metal barn
and garage for storage.
• Lease F consists of three (3) acres of sprinkler-
irrigated pasture. The lease area has 0.25 cfs of
water. The lease was actively managed for 4 years
but since has been mutually terminated. The
lessee installed a pump which utilizes the cistern,
which is filled by a ditch, and electricity installed
by the county. Potatoes were grown successfully
on Lease F for one year.

2.7 FARMSTEAD AREA
The purchase of Glassier Ranch included a number of
structures within the old farmstead area that vary in
structural condition. The main homestead, or Glassier
House, sits in its ranching context, with its associated
buildings, between Hooks Spur Road and the Roaring
Fork River. The house and adjacent structures are
an important contribution to the cultural history of
the mid-Roaring Fork Valley. The house has much
of its original material but has significant deferred
maintenance issues, making it uninhabitable. The
home has been vacant since 2009. The nearby
buildings suggest a progression in a ranching family’s
fortunes, from a one-room log cabin located behind
the house to a more substantial, two-room brick
house (more recently used as a chicken coop).
Open Space and Trails has retained the structures
of historic interest or potential utility to agricultural
lease operations, while removing some of the semi-
permanent and non-permanent structures on the
property, including old trailers, a camper and two
metal-sided grain bins.
OST has been managing the Glassier House over the
last five years according to Option No. 3 in the 2015
Management Plan, retaining the house without a
tenant/occupant and maintaining the structure in its
current condition, completing minimal work to shore
up the roof in order to limit further damage.
Many of the “accessory structures” have historic
interest but are in poor condition and have been in
various states of disrepair since before the property
was acquired. The wooden barn, bunkhouse cabin,
and smithy are interesting elements that contribute
to the farmstead’s scenic and historic character. The
bunkhouse has been the subject of vandalism since
the County took ownership of the parcel, but the
other structures on the site have largely been left
alone since OST’s acquisition.
Some of the more recently constructed farmstead
structures, including the large metal barn, small,
metal-sided garage, and livestock shelter/loafing
shed are being used by agricultural leaseholders
for their operations. The large metal barn/garage
is approximately 1,925 square feet and is used
primarily for agricultural storage, including some of
the storage needs for the OST program. The small,
metal-sided garage is utilized by the Lease Area E
lessee and supports the current small-scale vegetable
and flower production. It also houses the well pump
for the farmstead. The Lease Area E lessee has made
improvements to enclose the open side, providing
more protection from the weather. The metal-sided
garage is not tied to any lease area and is being
utilized by permission from OST. The livestock shelter/
loafing shed has been cleaned up by the Lease Area F
lessee and is used intermittently for hay storage.
In addition to the structures, heritage fruit trees are
located within the farmstead area and in a few other
locations on the open space. The trees include apples,
pears, apricots and cherries.
Limited soil sampling was completed on Lease area
D, E, and F during Fall of 2015. Soil tests were taken
with the help of NRCS staff and were analyzed using
the Haney Test, which uses minerals and nutrients to
evaluate soil health. The results were interpreted by
NRCS staff and generally the soils were good or rather
no issues were identified. NRCS staff advised that
these results vary greatly based on numerous factors
and so any future soil testing should be focused and
precise. That being said, it gave OST staff a general
idea of the status of the soils and provides baseline
information against which to track changes over time.

GLASSIER HOUSE
The Glassier House is a characteristic, two-story, brick ranch house with a cross
gable roof, probably built around the beginning of the 20th century. It is one of a
handful of substantial brick ranch houses from that era that occupy the midvalley.
The home’s origins are unclear. Eagle County records trace ownership of the
homesite to W.L. Girdner in 1912. No further records could be found, however,
the house was central to the 530-acre Glassier Ranch. Multiple generations of
the family lived in the house until its last resident, Freda Glassier, died in 2009.
Historic newspaper accounts indicate bricks were being produced in Emma, and
used in construction in Aspen and Leadville in the early 1900s. The construction
of “commodious” brick houses in the greater Emma area also made news.
The Glassier House has the classic front gable and side-wing configuration that
can be seen throughout the valley in many forms. In addition, it has elegant
details such as the projecting bay in the front gable, segmental arched windows
and decorative brackets along the gable end that give the house an element of
refinement.
Two one-story additions were added, probably in the 1950s, to improve the
home's functionality and house the home's only bathrooms. Much of the
historic fabric of the original house remains and despite considerable deferred
maintenance, it would be feasible to restore the home.
One of the two additions to the Glassier House is visible in this view of the
rear of the structure, as is work to shore up the roof.

The Rio Grande Trail runs through the property,
connecting upvalley to Basalt and downvalley to
Carbondale. The Rio Grande is a year-round, multi-
use, paved trail that sees over 40,000 users annually
on this section. A soft-surface trail parallels the Rio
Grande Trail from the Hooks Spur parking area to the
boundary of Glassier Open Space. The Rio Grande
Trail is seasonally closed between Rock Bottom Ranch
and Catherine Store Road from Nov. 30th through
April 30th for the protection of wintering wildlife.
Wildlife Protection / Seasonal Closure
In order to protect wildlife, dogs are not permitted on
the Glassier property, unless specifically allowed in an
agricultural lease for agricultural purposes. A seasonal
closure is in effect to protect wintering wildlife.
2.8 RECREATION
2.8.1 TRAILS– MOUNTAIN BIKING, HIKING/RUNNING AND EQUESTRIAN USE
Recreational trail development and improved access
to public lands on the Crown was a significant focus of
the 2015 plan. The Crown is a destination for a variety
of recreationalists, including hikers, bikers, motorized
users, equestrians and hunters. The Glassier trails, in
conjunction with additional trail development on the
Crown, have greatly increased the trail offerings in the
midvalley.
Glassier Open Space opened to recreational use in
May 2015 with access along the existing ranch road to
the Crown available for use. The current Glassier Trails
were constructed in 2016 after careful planning with
input from hikers, bikers and equestrians. A multi-use
trail serving all non-motorized users traverses the
agricultural fields connecting from the Rio Grande
Trail to the toe of the red cliffs where two, user-
separated, natural-surface trails lead to the boundary
of the BLM land on the Crown. The trails flank the
two-track access road. The eastern trail was designed
to accommodate both foot and mountain bike travel
in both directions, while the western trail serves foot
A mountain biker rides through the sage and piñon-juniper landscape.

Trail Use
OST staff has been monitoring the amount and
types of use the Glassier Trails receive to help inform
management decisions and monitor for compliance
with the rules and regulations. While the Glassier
trails opened for use in August, 2016, the summer of
2017 was the first full season of use with popularity
of the trails further gaining interest after the parking
area at Hooks Spur and Hooks Lane was constructed.
Trail counters and camera counts fail to capture all
users; however, they provide useful insight into the
general trends and types of use. Over the six months
that the trails are open to the public, the bike/hike
trail use, which includes hike and bike visitors in
both directions, averaged almost 15,000 annual user
counts from 2017-2019. Equestrian trail use, which
includes hike and horse users in both directions,
averaged 374 total user counts for the same period.
In 2019, the average use per month was about 2,250
total users up from about 1,650 in 2017 (counted by
the Trafx trail counter). Together the counter data
and ranger observations show that visitation to the
property has increased over time.

All users counted in both directions. Note that 2019 had a very late
spring and the trails were not usable early in the season, which may
have influenced the number of users.
Glassier provides trails for a diversity of trail users, with trails for
equestrians, mountain bikes and hikers/trail runners.

Existing Conditions | Glassier Open Space Management Plan 46
• No boat launching.
• No parking on Hooks Spur Road.
• No winter recreation.
• Only open during daylight hours.
• Pack in, pack out.
• No hunting on Glassier Open Space.
• Non-motorized hunting access is allowed. Hunters
accessing the Crown on foot from Glassier Open
Space must keep weapons unloaded while on the
Glassier property.
• Weed-free feed required for horses at Glassier,
consistent with BLM requirements on the Crown.
Compliance with Rules and Regulations
Users generally respect the use restrictions and
seasonal closures that are intended to protect wildlife
and public safety. Rangers have had a consistent
presence at Glassier Open Space since 2015. They
have emphasized educational contacts and have
made gains in compliance over the last five years.
Violation of the dog prohibition remains a small, but
consistent problem. And while seasonal closures are
generally respected, there have been some violations
as the opening date nears in the spring. Observations
indicate increased use of ebikes and Onewheels;
both are motorized uses, which are prohibited on the
open space. These violations may be attributed to the
differences in regulations on the adjacent BLM lands.
2.8.2 FISHING ACCESS
A small portion of the Glassier property borders the
Roaring Fork River and fishing access is permitted
from May 16 to Nov. 30. Parking is provided at the
Hooks Spur lot (0.5 miles from the farmstead). Anglers
have pedestrian access through the farmstead area
to a primitive trail with access to the river. Once an
angler has reached the waterway, they must walk
within the course of the river. This river access point
receives relatively low usage.
Boat launching and commercially guided fishing are
not allowed. The nearest boat launch is approximately
0.75 miles upstream. Although not directly connected
to the Glassier property, the Town of Basalt owns
river property 0.25 miles upstream and the Forest
Service owns a significant river section 0.25 miles
downstream.
2.8.3 RULES AND REGULATIONS
The current rules and regulations for Glassier Open
Space include:
• No dogs allowed on the Glassier property, unless
specifically allowed in an agricultural lease for
agricultural purposes.
• No commercial use except for permitted
agricultural uses.
• No commercial fishing.
• No commercial use of Glassier Trail.
The trailhead kiosk outlines the rules and regulations for using the trails and educates the public about the agricultural practices taking place on the property.
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Glassier Open Space Management Plan | Existing Conditions 47
Educational, environmental and agricultural tours,
and the sale of agricultural products produced on
site, can be accommodated on a case-by-case basis,
separate from the aforementioned special-use
requirements, and are coordinated with the lessees
and Pitkin County. Such uses are not considered
commercial uses.
Over the last five years, special events have been
limited to non-profit use of the trails. Aspen Cycling
Club was issued a special-use permit in 2018 through
2020 for an annual race utilizing Glassier Open
Space as part of its summer race series. Roaring Fork
Cycling was issued a permit in 2018 through 2020 for
season-long youth cycling programs. Aspen Valley Ski
and Snowboard Club secured a permit in 2020 for
season-long dry-land training at Glassier Open Space,
including mountain biking and trail running.
2.9 COMMERCIAL USE AND SPECIAL EVENTS
2.9.1 Commercial Use
No commercial use is permitted at Glassier Open
Space or the Hooks Spur parking area. This includes
but is not limited to: film or photo shoots, for-profit
race events, commercial guiding, etc.
2.9.2 Special-Use Permits/Events
Per the 2015 Management Plan, any event involving
more than 15 people is required to obtain a Special
Use Permit from Pitkin County Open Space and
Trails and comply with Eagle County’s special event
regulations. Up to two events are allowed per year.
The trails remain open to the public during events and
no event infrastructure is allowed on Glassier Open
Space.

Planning Process and Public Comments | Glassier Open Space Management Plan 48
3.1 PLANNING PROCESS
Staff spent the summer of 2020 meeting with
partners and gathering data on existing conditions.
The initial round of public comment was open for the
month of August and was focused on what the public
likes, what they would to see change, and specific
questions regarding the house and farmstead area.
Staff reviewed the 2015 plan, the existing conditions
and public and partner comments to develop the
draft management plan update. The draft update was
presented to the Open Space and Trails Board for
review and comment on Oct. 1st, 2020. Public input
on the draft plan was collected from Oct. 2nd through
Nov. 6th.
3.2 PARTNER COMMENTS
Colorado Parks and Wildlife (CPW) – Staff reached
out to Colorado Parks and Wildlife to gather input
for the planning process and met on-site with CPW’s
District Wildlife Manager, Area Wildlife Manager,
and Habitat Coordinator. CPW staff reviewed how
wildlife needs are being met and options to further
support various wildlife species. CPW staff noted the
high wildlife use of the property as an indication of
its value, especially for ungulates in the non-summer
months, and recommended maintaining the seasonal
closure to recreation and the year-round prohibition
of dogs on the property. CPW staff were supportive of
changing the seasonal closure date to align with the
current RFTA closure of the Rio Grande that runs Nov
30-Apr 30, citing clarity for the public, effectiveness
of aligned closure dates for wildlife protection, and
some flexibility in anomalous years. CPW watches
snow depths, weather conditions and forage
availability each winter and will continue to advise
OST on adjustments to the seasonal closure dates
to extend the closure in high snow years. CPW staff
also commented on the low forage value for cattle
or wildlife on the agricultural lease areas closest to
the road, and indicated they may be willing partners
on a land management plan that seeks to improve
the value of pasture area. CPW recommended
against lifting the dusk-to-dawn closure to protect
the nocturnal wildlife usage for small mammals, deer
and elk. The draft plan has been revised to reflect
maintaining the dusk-to-dawn closure.
Eagle County – OST staff discussed multiple topics
with Eagle County staff including: enforcement,
funding partnership, plan adoption and management.
At this time, Eagle County does not have a specific
historic preservation fund, but the case can be made
to help fund worthy projects from the Open Space
or General Funds. Eagle County staff will work with
their Boards on the adoption of the 2020 Glassier
Management Plan.
Town of Basalt - OST staff presented the draft plan to
the Parks, Open Space and Trails (POST) Committee at
their Oct. 14th meeting. The POST Committee voted
to endorse the plan and appreciated the uniqueness
of the site and its ability to support multiple
community goals. They are in favor of spending funds
wisely to preserve the historic farmstead as a way
to provide housing for either an on-site manager or
lease holder and requested the addition of bike racks
near the trailheads.
Basalt planning staff submitted additional comments
in support of the plan and emphasized the
importance of more direct actions to address climate
change and encourage ecologically responsible
farming practices. Town staff is supportive of restoring
the historic home if financially feasible, and would
prefer the housing be tied to agricultural activities or
a caretaker of the property.
Bureau of Land Management - BLM staff provided
email comments regarding their management of
the Crown, which reinforced their management
focus described in the agency's Special Resource
Management Area Plan (summarized in Section 3.4.6).
They confirmed they would be open to partnering on
habitat improvement projects that span our property
boundaries, such as oak mastication or controlled
burns, and that they have the authorization within the
Resource Management Plan to extend the April 15th
opening of the Crown to mechanized use per CPW's
seasonal recommendations. BLM staff clarified the
current grazing permit holders, which inform who has
motorized access through Glassier Open Space and
during what times of year their permits are active.
Roaring Fork Valley Horse Council – The Horse
Council submitted a survey comment expressing
their love for Glassier, their desire for a Western
Heritage Museum and a request that the Open Space
program consider the museum as a potential use

for the Glassier House. The council indicated it is
proud to partner with OST and the BLM on routes
for horseback riders and hikers and that its members
look forward to a trail connection between Glassier
and Nancy’s Path, though they raised concerns
regarding the difficulty of the trail for horses and their
riders. Their comments on the draft plan requested
an additional beginner/intermediate meadow trail
around the perimeter of the Glassier property. While
staff discussed this possibility, it is not compatible
with the agricultural and irrigation requirements of
the lease areas and would have to cross a number of
lateral irrigation ditches.
Roaring Fork Mountain Bike Association – RFMBA
submitted a survey comment requesting directional
mountain bike trail routes on Glassier, and specifically
to consider opening the equestrian trail to uphill
mountain bike traffic. If this is not possible, an
additional route was requested to facilitate the
separation of directional uses, as has been successful
in other areas of the Crown. RFMBA requested
continued monitoring of the types of use on the
Glassier trails and that the possibility for additional or
directional trails be considered in the future.
Rocky Mountain Farmers Union – The Roaring Fork
Chapter of the Rocky Mountain Farmers Union was
contacted and an email was sent by the president to
all members so they could participate individually in
the public process.

Planning Process and Public Comments | Glassier Open Space Management Plan 50
Natural Resources Conservation Service (NRCS) –
Staff met on site with the NRCS soil conservationist
to discuss feasible options to improve the agricultural
and wildlife values of the property. Among the ideas
discussed were federal funding opportunities for
irrigation and habitat improvements, capacity of
the NRCS to partner on improvements, and lessons
learned from neighboring properties. NRCS staff said
they would be happy to participate and assist the
county and lessee with improvements.
Neighbors – Staff reached out to neighbors of Glassier
Open Space to make sure they were aware of the
planning process and knew how to participate.
Staff received direct emails containing a variety of
comments. A major theme seemed to be care and
concern for the protection of wildlife, including
the river habitat. Comments regarding irrigation
were split between support for continued flood
irrigation versus advocating for irrigation efficiency
projects. Concerns were expressed about limiting
agricultural practices to those that are compatible
with a residential area. Some appreciated the current
rules prohibiting ebikes/motorized use/dogs and
the separation of trail users, while others expressed
concern about overuse on the Crown. In regard to
trail use, many neighbors voiced support following
the release of the draft plan for maintaining the dusk-
to-dawn closure to protect wildlife and were wary
of changing the closure date. Many said they do not
want to see the house occupied, but a few did say the
house should be managed/lived in by a private entity,
or that multiple farm lessees should have the ability
to access and utilize the farmstead area.
3.3 PUBLIC COMMENTS
INITIAL PUBLIC INPUT: Staff gathered initial public
comments via an online survey that was open and
promoted to the public during the month of August. A
total of 272 responses* to the 5-question survey were
received. The survey asked participants what they
love about Glassier Open Space, what they would
like to see changed, about their level of support for
investing OST funds in restoring the Glassier House,
and their ideas for activating the farmstead area.
Most of the different user types were represented
in the survey responses, including neighbors, hikers/
runners, mountain bikers, equestrians and wildlife
watchers, though it is acknowledged that many enjoy
the open space in multiple ways. The feedback also
represents a variety of age groups and visitors from
throughout the Roaring Fork Valley, though almost 50
percent of respondents indicated they reside in the
midvalley area of Basalt, El Jebel, Willits and Emma.
Full results are included as Appendix A.
What people love about Glassier Open Space:
In general, those who responded to the survey
expressed genuine appreciation for the Open Space
and Trails and the multiple purposes it serves. Many
people commented on the proximity/convenience/
ease of access to the midvalley population centers.
People praised the beauty and views, open space,
wildlife, heritage elements of the site and the
importance of agricultural preservation. Many
appreciated that multiple uses are working together
on one site. They appreciate the well-designed
and well-maintained trails that provide access/
connectivity to the Crown. A handful of respondents
appreciate that the trails accommodate a variety of
abilities and that user groups have separate trails,
enhancing the trail experience and safety. Glassier
Open Space is a well-loved community asset serving
users throughout the Roaring Fork Valley.
What respondents would like to see changed: A
theme among responses was the concern about the
overuse of the area and congestion on the trails,
and the potential impacts on wildlife as well as
safety/quality of the trail user experience. There was
interest – primarily from mountain bike respondents
– in more trail development and/or redesignation
to facilitate directional trails. There was, however,
also support both from mountain bikers and other
users to preserve the existing two-way trail network
with separated uses as currently designed. Some
respondents proposed limiting foot travel to the two-
track road or equestrian/foot trail and redesignating
the current bike/hike trail as a mountain bike-only
trail. People noted the benefit of the current system’s
ability to accommodate multiple user groups or
rides of different lengths with the ability to go both
up and down. Additional comments indicated an
interest in aligning closure dates with the Rio Grande
Trail and the Crown to avoid confusion, adding/
improving signage, and adding roll-over cattle guards
as an alternative to gates. There were also a handful
of responses both for and against the current dog
restriction.
Other desired improvements for the property that
survey respondents expressed included improving
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Glassier Open Space Management Plan | Planning Process and Public Comments 51
agricultural activities and the viability of small farms/
local food production. Providing on-site housing
was expressed as a need, as were improvements
to irrigation and agricultural infrastructure (such as
ditches and barns).
Glassier House Potential Restoration: The majority
(51%) of those who responded to the initial
survey were either very supportive or somewhat
supportive of expending funds to restore the Glassier
House, while 15% were either somewhat or very
unsupportive of spending funds on restoration.
Respondents grappled with the benefits versus the
substantial expense associated with restoring an
historic structure. Many conditioned their support
for using the house for either housing or another
public use on first understanding the cost. Among
many proposed uses of the farmstead and Glassier
House, a theme among responses that supported
having housing on site also said the tenant should
be a steward or caretaker of the land (such as an
agricultural lease holder) or someone responsible
for overseeing the property, including the potential
for a county employee or other allied conservation
professions. There were sentiments that this property
is an important part of the valley’s culture and that
housing for farmers on the land is essential for their
long-term success. There were also respondents who
were not in favor of using the home or having housing
on the property, or did not feel that open space funds
should be used in this way.
Future Use of the Farmstead: There were a number
of creative suggestions on how to activate or better
utilize the farmstead area, which encompasses the
Glassier House and surrounding lands between
the Roaring Fork River and Hooks Spur Road.
Comments ranged from investing in on-site housing
and infrastructure for lessees, to ideas to increase
public use/access to the site with interventions as
minimal as walking trails through the farmstead and
farm dinners, to community garden plots, museums,
animal husbandry and educational facilities. A
significant theme in the responses was support for
leasing the land for local food production/community-
supported agriculture, with some additional
thoughts and ideas for partnerships with existing
agricultural non-profits or local farmers, encouraging
opportunities for education/youth engagement, and
growing food for schools or at-risk populations.

*As staff reviewed survey comments, it became apparent that one user was filling out multiple surveys and representing themselves as elected officials and local government representatives, among other false identities. After clarifying with those whose identities appeared to have been used (they confirmed they had not filled out the survey), and after conversations with the county attorney’s office, it was decided these survey responses would be removed from the results and not included as a valid submissions. In the future, all survey responses will require a functioning email address and staff hopes this unfortunate and illegal situation is not repeated. Additionally, it should be noted that some respondents answered both the survey and emailed their comments to staff. While email comments are accepted and have been included, staff has identified those who also submitted survey responses.

Planning Process and Public Comments | Glassier Open Space Management Plan 52
Two outreach days were held in October where staff was on site at the
parking area to provide a summary of the draft plan's action items,
answer questions and collect input from the public.
DRAFT PLAN COMMENTS: The draft plan was
available for review and promoted through OST's
email newsletter, the Glassier contact list, and social
media promotions to encourage the public to submit
their feedback from Oct. 2nd through Nov. 6th. Staff
received almost 100 survey comments on the draft
plan. In addition, staff spent two days in October at
the Hooks Spur parking area talking to over 40 visitors
about the draft and collecting their input. Those
who were using the Glassier Open Space or who live
nearby were appreciative of the open space and trail
opportunities provided and grateful to have the trail
system within the mid-valley.
There were a number of respondents who were
supportive of keeping Glassier available to livestock
farmers and noted the infrastructure requirements,
on-site housing, as well as the ability to have on-
farm sales as important elements for a successful
operation. There was general support for allowing
limited on-site housing tied to an agricultural lease
area or caretaker of the property.
Regarding the trail actions, responses were mixed
on the revised closure dates and the draft plan's
direction to remove the dusk-to-dawn closure with
many requesting that the closure be maintained.
Many noted the benefits of reducing confusion by
aligning the closure dates with neighboring lands;
however, there remains concern for the need to
protect wildlife. Many of those who identified
themselves as mountain bikers continued to advocate
for the implementation of a directional trail system.
Complete responses are included in Appendix B.

Glassier Open Space Management Plan | Management Actions 53
4. MANAGEMENT ACTIONS
The following management actions have been drafted
based on the existing conditions analysis and partner
and public comments. Some of the action items can
be implemented following plan adoption; others
require additional planning, engagement and design.
The Glassier Management Plan is on a five year
update schedule pursuant to the conservation
easements encumbering the property. Often
action items, studies, monitoring intervals, and/or
implementation steps can be longer than 5 years.
Taking time to understand a property, its relationship
to its surrounding environment and allowing time
for the community to become familiar with it, will
ultimately lead to better management decisions and
allow for continuing adaptive management overtime.
4.1 BIODIVERSITY AND AGRICULTURAL LAND MANAGEMENT ACTION ITEMS
Glassier Open Space embodies an important
opportunity, where innovative agricultural practices
can dovetail with biodiversity and natural resource
enhancements. The path forward to integrate
economically sustainable agriculture, more efficient
use of water, better utilization of open space property,
and improved wildlife habitat will take thought, time
and strong partnerships. The action items below are
all important pieces to achieving this objective to
meet the needs of both farming/ranching and the
local ecosystem.
4.1.1 MAINTAIN SEASONAL CLOSURE WITH AMENDED DATES
The seasonal closure of Glassier Open Space to all
modes of travel will be maintained. The fall closure
will continue to go into effect on Nov. 30th, while
the opening date in the spring will be amended to
April 30th. The goal is for the Glassier closure dates to
align more closely with those established by adjacent
land managers to ensure effective closures. Based
on current climate conditions, observed wildlife use
and input from CPW, the April 30th opening date still
meets the needs of wintering wildlife, in particular
offering deer and elk undisturbed access to high
quality forage in the early spring. This amendment
will minimize confusion for trail users by aligning with
the opening date for the adjacent Rio Grande Trail,
which is seasonally closed from just downvalley of the
The seasonal closure protects wintering wildlife such as
these mule deer, photographed before the Dec. 1 closure.
The gate at the entrance trail is locked during the
seasonal closure.

Management Actions | Glassier Open Space Management Plan 54
Buckhorn Trail and Catherine Store Road from Nov.
30th through April 30th (see Map 2). RFTA opens the
southernmost gate at Rock Bottom Ranch on April
15th to prevent users from being stuck within the
Rio Grande Trail seasonal closure area. The Glassier
closure will align with the main closure dates per
CPW's recommendations.
The adjacent BLM Crown area is subject to a winter
closure to mechanized use from Dec. 1st through
April 15th. The BLM may extend the opening date in
a given year based on conditions. OST will continue
to work with partners to align these dates, working
with guidance provided by CPW to amend opening
dates on Glassier and the Crown if warranted
based on seasonal conditions (e.g. snow depth,
temperatures, access to forage) to benefit wildlife
coming out of winter.
4.1.2 LEASE AREA MANAGEMENT
4.1.2.a - Redefined Lease Areas
- In 2015, Glassier Open Space was divided into
six agricultural lease parcels of various acreages
described in Existing Conditions Section 2.5:
Agricultural Lease Areas. Two large parcels (Lease A,
44.5 acres; and Lease B, 94.2 acres) were identified
based on historic/active use and an existing boundary
fence. Four small parcels (Lease C, 10.3 acres; Lease
D, 3.5 acres; Lease E, 0.6 acres; and Lease F, 3 acres)
were identified and developed based on historic use,
existing fences, existing break features, proximity to
the Glassier home and public comment indicating
interest in small-acreage lease areas.
Over the past five years, Leases C and D have not
been utilized; they will be taken out of the agricultural
lease portfolio. Agricultural producers familiar with
the property say the soil is really thin in the areas
and it was not worthwhile to put time into irrigating.
Lease C was previously a junked car lot and only
grazed in the fall and never hayed, Lease D was used
as a dry lot for horses. The animals would pasture in
the fall after the area was sub-irrigated and green and
then horses were fed over winter until spring.
The boundary of Lease B has been adjusted to
encompass the agriculturally viable and irrigated
area. The areas removed from the lease portfolio
will be evaluated as specified in Action Item 4.1.3:
Agriculture and Biodiversity Conservation Partnership,
but may be opened to fall grazing for Lease B
depending on conditions. There are no changes
planned for Lease A, E and F.
Limited storage for lessees is available in the large
metal storage building depending on availability and
need. On-site storage of mechanical equipment and
agricultural material is limited and clustered within
and around the existing structures.
4.1.2.b - Agricultural Lease Priorities
- Lease areas B and F have either been terminated
or reached their lease termination date, while lease
area A expires at the end of 2021. Lease E is currently
leased through Dec. 31, 2024. A Request for Proposals
will be released to obtain an appropriate lessee for
each area upon plan adoption or at the end of the
existing lease agreements.
OST will select lessees using the Pitkin County
Agricultural Lease Bid Process. In addition to the
evaluation criteria listed in the Process, lessees
proposing organic or natural food production without
the need of pesticides or herbicides, and local
agricultural suppliers, will be given priority.
Lessees proposing an agricultural operation involving
livestock are responsible for maintaining fencing to
control their animals and for any temporary cross
fencing.
During the leasing process, OST will work with
individual lessees on appropriate on-site farm sales /
food production, which will be included in each lease
agreement.
Fences in various states of disrepair across the property will

4.1.2.c - Fall Grazing and Vegetation
Management for Forage Enhancement -
For the benefit of wildlife, lease area B shall be
maintained to support transitional wildlife habitat
and a minimum of 50% of the land area will not be
grazed or have the vegetation cut or removed beyond
Sept. 1st to allow forage to be present for wildlife. The
lessee will be required to continue watering the lease
area after last cutting of hay. The goal is to allow for
about a month to 1.5 months of regrowth that serves
as high-quality forage for ungulates in the autumn as
they prepare for winter.
4.1.3 AGRICULTURE AND BIODIVERSITY
CONSERVATION PARTNERSHIP
Staff will work with partners to develop a long-
term, holistic plan that focuses on both agricultural
efficiencies and biodiversity improvement projects.
The plan will focus mainly on the agricultural area(s)
historically utilized by producers, evaluating where
OST can evolve current management practices to
both benefit lessees and improve wildlife habitat. As
part of the partnership and plan development, data
will need to be collected to help inform conversations
around irrigation practices, soil health and habitat
needs.
In addition to organizing interested partners, staff will
investigate grant opportunities, including (but not
limited to): NRCS, CPW's Habitat Protection Program
(HPP), Regional Conservation Partnership Program
(RCPP) and Environmental Quality Incentives Program
(EQIP).
Topics that will need to be discussed and evaluated
include (but are not limited to):
Hydrological Investigation – Examine current wet
areas across the property, determine their current
habitat and pasture values, evaluate impacts if
there was to be a shift in irrigation regimes, explore
mitigation alternatives if there are impacts, identify
innovative water operations to maintain irrigated
areas and allow for improved forage and wildlife
habitat.
Pasture Land Improvements – Assess options to
maintain and/or improve agricultural production.
Identify other opportunities to improve soil health
through land uses practices and/or compost
amendments.
Habitat Improvements – Determine which wildlife
species to serve, the target plant communities, and if
there is opportunity to provide a wildlife movement
corridor between upland areas and the river.
Potential partners include: NRCS, Eagle County,
agricultural lease holders, CPW, Home Supply Ditch,
and neighbors who may be interested in similar goals.
Start Date: 2021
Glassier Open Space encompasses a mosaic of
piñon-juniper, sagebrush and Gambel oak native plant communities.
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Glassier Open Space Management Plan | Management Actions 57
4.1.4 INTERIM PASTURE LAND IMPROVEMENTS
Former Lease Area C was the zone of car storage and
junkyard when Glassier Open Space was acquired.
Significant clean up and weed management has
occurred since the acquisition, but the site still needs
a focused attention to encourage desirable vegetation
growth. This area was specifically removed from the
agricultural leasing portfolio in order to focus on
productivity improvements. This area will be part
of the Agriculture and Biodiversity Conservation
Partnership described above but, in the interim,
staff will explore seeding with cool season grasses,
irrigation, and grazing disturbances as means to
stimulate productive vegetation growth.
4.1.5 DEVELOP POLICY FOR MICRO LEASE AREAS FOR POLLINATORS
OST staff will develop a policy to lease or sub-lease
small areas of Open Space and Trails properties to
support pollinator / honey production.
4.1.6 NATIVE PLANT COMMUNITIES
Upland shrublands will continue to be evaluated for
health and OST will work with adjacent landowners,
including the BLM, to implement any needed
interventions. These may include cheatgrass control
and oak treatments in areas of overly mature Gambel
oak to improve age-class diversity and reduce fire
fuels.
Riparian areas along the Roaring Fork River will be
evaluated to identify any needed interventions to
maintain habitat functionality. This may include
assessments of reed canarygrass extent, regeneration
of native trees and shrubs, and options for in-stream
habitat improvements.
4.1.7 WEED CONTROL
Addressing the abundance of noxious weeds and
invasive plants at Glassier is a long-term effort.
Clarification is provided here to define responsibilities
between OST and lessees. All agricultural lessees
are responsible for managing Colorado List A and B
noxious weeds within lease boundaries, per lease
agreements. OST is responsible for List A and B
species outside of the lease areas, including the
farmstead area until it is leased to a third party, and
within 3 feet to either side of OST-designated trails.
Flood irrigation on the agricultural fields.
Invasive cheatgrass (a Colorado List C noxious
weed) is a challenge in any future management
scenario. Its presence increases fire danger, as it is
highly flammable, and controlling cheatgrass is a
priority. OST will work with partners (lessees, BLM,
consultants) to address the cheatgrass present along
the trails, in the upland areas, in the agricultural lease
areas and around the farmstead. Results from OST’s
study of cheatgrass control in the Crystal River Valley
may inform actions to be taken at Glassier. OST will
monitor for effectiveness of any treatment and adapt
management practices accordingly.
4.1.8 OLD FENCE REMOVAL
Many sections of fence on Glassier Open Space
are no longer utilized and are in various states of
disrepair. Removal would facilitate ease of movement
for wildlife and clean up the property. OST will work
with partners and volunteers to conduct fence pull
projects.
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Management Actions | Glassier Open Space Management Plan 58
for agricultural producers or county/OST staff –
individuals who have a responsibility to the land.
Outlined below is the approach for exploring the next
steps at the Glassier farmstead. In order to facilitate
management of the site, the first step would be a
discussion about housing. Once a housing direction is
determined, it will help inform the decision regarding
the associated lease area management. If at any
point it is determined that the cost of rehabilitating
the home for residential use is too great or there
are other unforeseen challenges that make utilizing
the home infeasible, alternatives can be explored.
These may include a long-term lease of the house to
a third party (who can rehabilitate and then inhabit
the house) or leaving the home in a state of arrested
decay. An arrested-decay approach means no attempt
would be made to improve the home, other than
stabilizing it for safety. It would be allowed to be
reclaimed by nature over time, while remaining a site
of historic interest.
4.2 FARMSTEAD ACTION ITEMS
Planning for open space properties with existing
structures continues to be one of the more difficult,
but potentially enriching aspects of management.
Structures can help facilitate agricultural use and
having a resident on site, taking care of a property
and acting as its eyes and ears, can provide a level
of attention that brings a property to life and allows
it to flourish. The initial challenges (cost of structure
rehabilitation, new construction, leasing process, etc.)
need to be evaluated against the long-term goals for
the property and the Open Space program’s capacity.
Most respondents to the initial public survey were
supportive of spending money to help restore the
Glassier House, although the initial survey questions
did not include a dollar amount. The open-ended
survey question about activating the farmstead
included many requests for publicly accessible
agriculture, as well as support for having residents
on site. A variety of ideas were presented regarding
partnering with local non-profits or becoming a site
for expanded operations of existing entities in the
area. Suggestions also included providing housing
Glassier farmstead.
DocuSign Envelope ID: BF14B2AD-F480-442C-9091-F7D187535DCD
Glassier Open Space Management Plan | Management Actions 59
4.2.3 FARMSTEAD LEASE PROCESS
Until a decision is made regarding on-site housing,
lease areas E and F will be leased through the Pitkin
County Agricultural Lease process on an interim basis
for up to 5 years or until a determination is made
regarding farmstead activation. See section 2.4.7 for
more details on the Pitkin County Agricultural Lease
process.
4.2.4 OPEN SPACE RESTORATION PROJECT STAGING
Regardless of leasing decisions, a small portion of
the farmstead will be designated for staging of Open
Space and Trails restoration projects. These include,
but are not limited to:
• Storage: Cool, dry place for seed mixes, fence
materials, irrigation components, mulch, straw,
fertilizer, erosion-control matting and pumps, as
well as potential storage of larger equipment such
as a hydroseeder and strawblower.
• Plant staging: Place to store willows as they grow
out roots, and house container plantings intended
for restoration projects if timing doesn’t align
between delivery and installation.
• Large equipment storage/cleaning area.
4.2.1 GLASSIER FARMSTEAD ACTIVATION
To successfully activate and manage the Glassier
Open Space farmstead, a residential tenant who is
a steward or caretaker of the surrounding land is
needed. OST staff will work with partners who are
interested in the potential of future housing and/
or preservation to evaluate the options for on-
site housing. These include, but are not limited to:
restoration of the existing farmhouse, modified
rehabilitation of the existing farmhouse, separate
additional dwelling unit(s), and/or replacing the
home with new construction. Staff will also research
and identify funding partnerships and/or release a
“request for concepts.”
The purpose of the “request for concepts” would be
to determine the level of interest from community
members or groups for an extended lease of the
Glassier farmstead. Understanding the level of
interest would help guide the decision-making
process regarding housing. Additional priority will
be given to concepts that have a community benefit
(for example: providing local food for school lunch
programs, food pantries, senior programs, etc.).
Priority will also be given to concepts representing
a minority population, including persons with
disabilities.
All of this information would be brought back for an
Open Space and Trails Board discussion. If there is
no apparent partner or interested lessee, the board
could move forward with a focus on providing OST
staff/partner housing and then leasing areas E and F
separately. The board could also decide to lease the
farmstead long term to a third party, or do nothing.
4.2.2 FARM STRUCTURE REHABILITATION
There are a few structures visible from Hooks
Spur Road that are an important part of the scenic
viewplane and have potential to serve a useful
agricultural purpose. In addition to the housing
evaluation, staff will work with the county’s historic
preservation officer to determine the options for
structure stabilization – the barn and the chicken
coop being the two most visible potential projects.
This information will be presented to the Open
Space and Trails Board for a discussion as it relates
to the program’s overall mission, and with regard to
potential interest from other partners or lessees.

4.3 RECREATION
Providing recreational access to adjacent public lands
was one of the important open space values identified
when Pitkin County partnered in the purchase of the
Glassier Open Space properties. Significant resources
over the first couple of years of ownership were
dedicated to the construction of trails connecting
to the Crown and associated amenities such as the
signage and parking area.
The public comments collected to inform this
management plan update express appreciation for
the trail experience, the ease of access within the
midvalley and the safety provided by separating
user groups. There were also requests for additional
trails or directional trail configurations on Glassier
Open Space, as well as support for maintaining the
existing experience without significant changes.
Careful consideration was given during the trail
design process to create an enjoyable trail experience
for both climbing and descending on bike, foot and
horse. The design utilized existing vegetation to
screen the trails and minimize their visual impacts
and maximize views from the trail over the valley.
The sustainable design maintained slopes to support
native revegetation. Little additional space for new
trail connections to the Crown exist that would also
respect the above-mentioned objectives. Open Space
and Trails also has a responsibility to support multiple
uses, which are currently accommodated at Glassier
Open Space.
Improvements to recreation over the next 5-year
period focus on minor tweaks to the current trail
system, the addition of an anticipated foot and horse
trail connection and better alignment of the seasonal
closures with the BLM.
4.3.1 BIKE/HIKE AND EQUESTRIAN/HIKE TRAILS TO THE CROWN
The primary recreational focus of Glassier Open
Space is the two natural-surface trails that connect to
the Crown. To enhance safety and improve the trail
experience, separated trails have been developed
for mountain bikes and equestrians; hikers/runners
can choose either of the two trails. Bike, equestrian
and pedestrian users are all allowed to use the two-
track road. These trails will be maintained under
their current designations, subject to the seasonal
closures, and rules and regulations for Glassier Open
Space. Both trails allow for uphill and downhill travel
and require users to travel at appropriate speeds
to safely pass. Other than regular maintenance as
warranted, no specific improvements, directional
trails or restrictions are called for at this time. Any
trail work should maintain the current trail character
and experience.
4.3.2 NANCY’S PATH CONNECTION
Open Space and Trails will work on identifying an
alignment through Glassier Open Space and adjacent
easements to create an equestrian and hiking trail
connection between Nancy’s Path and the Glassier
Open Space. The potential natural-surface trail for
equestrian and foot travel will be approximately one
mile in length and will facilitate a loop trail linking
Nancy’s Path, the Crown and the Glassier Equestrian/
Foot Trail. The trail will utilize Glassier Open Space
and the Emma Farms trail easement, acquired by
Aspen Valley Land Trust in 2015 for this purpose. The
easement does not allow for bicycle use or dogs,
which aligns with the use restrictions for Nancy’s
Path. Parking for Nancy’s Path is provided on the
easement held by OST on Happy Day Ranch. The BLM
has been working with the Roaring Fork Valley Horse
Council on improvements to the portion of Nancy’s
Path on BLM lands, however, the extended loop will
be an advanced or expert level horseback ride due to
the technical riding required on Nancy's Path.
Potential Partners: AVLT (easement holders); Emma
Farms (property owners); RFOV and Roaring Fork
Valley Horse Council; Happy Day Ranch and Emma
Farms property owners.
Start Date: Planning 2021, Construction 2022
Budget Implications: $40,000 - $55,000 (based on
$7-$10 per linear foot estimate; may require more
if additional infrastructure, culverts or bridges are
required).
4.3.3 IDENTIFY LOCATIONS TO ADD BENCHES AND BIKE RACKS
OST will evaluate the potential of adding a bench
and bike racks just above the Home Supply Ditch at
the start of the Bike/Hike and Equestrian/Hike trails
as well as a bench at a scenic overlook along the
trail(s). No memorial opportunities are available on
Glassier Open Space; however, there are memorial/
commemorative opportunities along the Rio Grande
Trail.

4.3.4 FISHING ACCESS
A small portion of the Glassier property borders the
Roaring Fork River and fishing access is permitted
outside of the seasonal closure dates. Parking is
provided at the Hooks Spur lot (0.5 miles from the
farmstead). Anglers have pedestrian access through
the farmstead area to a primitive trail with access to
the river. Once an angler has reached the waterway,
they must walk within the course of the river. Boat
launching and commercially guided fishing are not
allowed.
4.3.5 PROPERTY ACCESS/PARKING
The Hooks Spur parking area provides parking for trail
and river access. No parking is permitted along Hooks
Spur Road. The parking area is subject to Restrictive
Covenants (Reception No. 623905) prohibiting special
events, exterior lighting, temporary or permanent
structures over 500 square feet, and camping/
overnight parking. OST will evaluate the potential
of adding signage and improvements to delineate
equestrian trailer parking.
4.3.6 RULES AND REGULATIONS
The rules and regulations for public use specific to
Glassier Open Space have been working well and
support the open space values for the property. As
described in Action Item 4.1.1, the seasonal closure
dates have been amended to align more closely with
RFTA and BLM regulations. Additionally, the property
does not allow for motorized access including use by
e-bikes, one-wheels and other motorized modes.
Rules and regulations specific to Glassier open space
include:
• No dogs allowed on the Glassier property, unless
specifically allowed in an agricultural lease for
agricultural purposes.
• No commercial use except for permitted
agricultural uses.
• No commercial guiding, including fishing, boating
or trail use.
• No boat launching.
• No commercial use of Glassier Trails.
• No winter recreation. Seasonal closure in effect
from Dec 1st through April 30th.
• Trail closure from dusk to dawn.
• Pack in, pack out.
• No motorized use, including e-bike use, unless
specifically allowed in an agricultural access
agreement or lease.
• No parking on Hooks Spur Road.
• No overnight parking or camping at Hooks Spur
parking area.
• No hunting on Glassier Open Space.
• Non-motorized hunting access is allowed. Hunters
accessing the Crown on foot from Glassier Open
Space must keep weapons unloaded while on the
Glassier property.
• Weed-free feed required for horses at Glassier
Open Space, consistent with BLM requirements on
the Crown.
OST will continue to work with Eagle County to
support the enforcement capabilities of Open Space
and Trails Rangers.

4.4 COMMERCIAL USE AND SPECIAL EVENTS
4.4.1 COMMERCIAL USE
No permits will be issued for commercial uses at
Glassier Open Space or the Hooks Spur parking area;
this includes but is not limited to: film or photo
shoots, for-profit race events, commercial guiding,
etc. Commercial use on agricultural leases such as
farm sales or food production will be managed on a
case-by-case basis pursuant to the annual operating
plan associated with the agricultural lease area.
4.4.2 SPECIAL EVENTS
Any event involving more than 15 people is required
to obtain a Special Use Permit from Pitkin County
Open Space and Trails and comply with Eagle County’s
special event regulations. Up to two events are
allowed per year. The trails remain open to the public
during an event and no event infrastructure is allowed
on Glassier Open Space.
Educational, environmental and agricultural events/
tours can be accommodated on a case-by-case
basis, separate from the aforementioned special
event requirements, and will be coordinated with
the lessees and Pitkin County. Such uses are not
considered commercial uses.
4.5 OST FACILITIES AND MAINTENANCE
4.5.1 RECREATIONAL USE AND WILDLIFE MONITORING
Open Space and Trails will continue to monitor
recreational use in order to understand the amount
and types of use on the Glassier trails as well as
compliance with seasonal closures and other rules
and regulations. Staff will follow the methodology
established over the last few years and evolve
it as needed. This includes, but is not limited to,
trail use counts using Trafx counter data and two
motion-triggered wildlife cameras placed in different
locations.
4.5.2 PARKING LOT MAINTENANCE
OST maintains the Hooks Spur parking lot as needed,
including irrigation of the screening and vegetation.
The lot is not plowed in the winter.
4.5.3 WASTE FACILITIES
No trash receptacles, dog pots or bathroom facilities
are located on site or in the parking area. Visitors
have access to the seasonal port-a-potty and trash
receptacles provided by RFTA adjacent to the Hooks
Spur parking area and are responsible to pack out
what they pack in.
4.5.4 NOXIOUS WEED MANAGEMENT
Please refer to section 4.1.7: Weed Control.
4.5.5 WATER RIGHTS
Open Space and Trails will work with lease holders to
exercise Glassier Open Space water rights.
4.5.6 SIGNAGE
Per the 2015 management plan, a trailhead kiosk was
installed at the entrance gate along the Rio Grande
Trail and wayfinding signage leads users through the
agricultural lease areas to the user-separated routes
and onto the BLM lands. Signage was also placed to
identify private property and remind users to remain
on the designated trails. Any new signage must
follow the 2014 Pitkin County OST Signage Design
Guidelines. A second kiosk is currently designed
and planned for installation at the parking area
to supplement the existing kiosk at the property
boundary just off the Rio Grande Trail.
Additional needs include signage to identify the public
river access through the farmstead area, directing
anglers to the river, as well as identifying angler
parking at the Hooks Spur lot. OST will also work with
the Basalt Regional Heritage Society as a part of the
Rio Grande Node Plan to add interpretive signage at
the existing kiosk locations. The signage will help tell
The Hooks Spur parking lot.

the families that have contributed to conservation in
the Emma area.
4.5.7 GATES
With the current lessees, the two gates through the
agricultural fields have only been needed for a couple
of weeks in the spring and again in the fall; they have
otherwise been locked to the open position. If, in the
future, other agricultural operations require the gates
to be closed for more of the summer season, OST can
explore the use of roll-over cattle guards at the two
gate crossings in the lease areas to improve the trail
experience and minimize the potential for gates to
be left open. Staff has been working with RFMBA to
install a roll-over cattle guard at the boundary with
the BLM land (fall 2020) to minimize the number of
gate crossings and minimize the potential for gates to
be left open.
In the mean time, when gates are not needed to
contain livestock, staff will continue to work with
lease holders and lock them in the open position.
