Browns Canyon is one of the last pristine canyons in Colorado. My river company runs thousands of people down the Arkansas River and their eyes light up as they can still see the evidence of mountain lions and big horn sheep roaming up and down the canyon.

Browns Canyon is topographically and ecologically one unit of wild land divided in its administration between the BLM and the Pike-San Isabel National Forest. The BLM has recommended the westerly portion of the area for wilderness designation. In its RARE II process, the Forest Service did not recommend the Aspen Ridge unit for designation, but in viewing the proposed wilderness as a whole, it becomes clear that Aspen Ridge is an area with outstanding wild qualities. This opinion is shared by an overwhelming majority of citizens who commented during the two agencies' wilderness study processes.
Streams have cut
steep gulches through the pinkish granite and metamorphic rock
of the area. Pinyon-juniper forest dominates the arid lands in
Browns Canyon along the Arkansas River. The vegetation changes
dramatically as elevation increases, giving way to Douglas fir,
ponderosa pine, and the stands of aspen for which Aspen Ridge is
named. Aspen Ridge at 10,000 feet affords magnificent views of
the 13,000 and 14,000-foot peaks of the Sawatch Range to the
The area is an
important wintering ground for deer and elk, according to the
Colorado Division of Wildlife. Twenty bighorn sheep were
reintroduced into Browns Canyon in 1980, with an additional 20
in both 1982 and 1985. It is estimated that there is currently a
herd of 135 bighorns whose range includes Browns Canyon and
portions of Aspen Ridge. Other mammals found within the area
include mountain lions, black bears, bobcats, foxes, coyotes,
pine martens and many smaller animals. Eight species of raptors
have been sighted in the area, including golden
eagles, prairie falcons, and great-horned owls.
Browns Canyon of the
Arkansas River is widely known among whitewater boating
enthusiasts. It is the busiest stretch of the river, totaling
more than 90,000 user-days annually, according to figures
compiled by BLM. Protection of the wild country surrounding the
river canyon will be appreciated by these visitors and the
tourist industry which they support. Hunting, hiking, fishing,
and backpacking are among the other numerous recreational
pursuits possible in the area.
Timber is not a valuable commercial resource of Browns
Canyon. The trees of the higher Aspen Ridge unit are mainly
ponderosa pine and Douglas fir in spotty stands. Topography and
low volumes per acre limit commercial opportunity. There have
been no past timber sales in Aspen Ridge and none are planned
for the future. The lower unit, Browns Canyon, contains only low
value pinyon-juniper woodlands in extremely rugged terrain.
Browns Canyon contains portions of several allotments. Very little grazing occurs within the proposed wilderness due to rugged terrain and lack of forage. The Forest Service manages most of Aspen Ridge with a wildlife emphasis but allows limited livestock grazing on the remainder.
There is no potential for oil and gas resources within the proposed wilderness owing to the igneous nature of the geologic strata.
The GEM mineral
evaluation of Browns Canyon by BLM reports that the area has
little or no mineralization of commercial value. There are
currently no active patented or unpatented mining claims within
Browns Canyon. Aspen Ridge contains several unpatented mining
claims covering a limestone/dolomite deposit, probably for
fluorspar. The limited size of the deposit and commonness of the
limestone, as well as its location on the edge and outside of
the unit, make for little wilderness conflict. Four patented
mining claims, totaling approximately 50 acres, exist within
Aspen Ridge along its eastern border. These are all inactive
with no vehicular access.
The boundaries of Browns Canyon do not include the Arkansas River owing to the railroad on the east bank of the river. The area is largely a headwaters area containing several ephemeral streams.
The wilderness area proposed by citizens includes both the BLM's Browns Canyon WSA and the major portion of San Isabel National Forest's Aspen Ridge Roadless Area. Citizens' proposed boundaries for Browns Canyon extend south along the Arkansas River's east bank to incorporate additional BLM lands in Railroad Gulch.
Citizens' proposed wilderness boundaries for the Aspen Ridge portion of the unit necessitate the closure for about three miles of the historic Turret Stage Route. This route is closed to vehicles at the BLM land boundary and has been mapped as closed by the Forest Service in the past. The closure of this vehicle route is necessary in order to retain the integrity of the wilderness. The closure point for the road would be north of the access required by cabin owners at Green Mountain, thereby meeting their need for access.
