Unit 15

Key features for orientation: Black Mountain and Yarmony Mountain provide glassing vantage points for the rolling terrain, while Gore Mountain anchors the eastern divide. Eagle Rock Lakes and Lagunita Lake mark reliable water and are good navigation references. Wheeler Basin and Long Park are major open areas worth knowing—they're natural travel corridors.

Lynx Pass and Yellow Jacket Pass are saddles connecting different drainage systems. Creek drainages like Wheeler Creek, Raspberry Creek, and Clear Creek are valuable navigation tools and often hold water. These landmarks help break the rolling terrain into manageable sections for hunting strategy.

Elevations span roughly 6,700 to 10,800 feet, with most terrain in the 8,000 to 9,500-foot band—solid elk and deer country. Dense forest covers the unit, primarily spruce-fir and subalpine types typical of the Gore Range interface, with ponderosa patches on lower exposures. Open parks like Long Park, Buffalo Park, and Deadman Park provide critical meadow habitat and travel corridors through the timber.

The rolling topography means forest grades into parks and back again frequently, creating edges that hold animals. Terrain is high enough to support year-round elk and mule deer, with pronghorn in the lower, more open sections.

Over 500 miles of roads thread through the unit, providing fair access without being heavily roaded. State Bridge and Copper Spur roads put hunters in from the south, while routes from Trapper and McCoy access from the north and west. The rolling terrain and dense forest naturally compartmentalize pressure—hunters tend to concentrate near major roads and parking areas rather than penetrating far into the rolling park-and-timber country.

This means that moderate pressure near access points gives way to lighter use farther in, especially on the steeper eastern portions near the Gore divide. Roads are passable but can be rough; conditions in early fall and late spring matter.

GMU 15 spans the high country of Routt, Grand, and Eagle counties, bounded north by U.S. 40, east by the Gore Range divide and Muddy Creek drainage, south by the Colorado River, and west by Colorado 131. State Bridge and the small communities of Copper Spur and McCoy serve as access points from the valley floor. The unit encompasses rolling upper-elevation terrain rather than dramatic alpine peaks, making it intermediate terrain for hunters accustomed to either lower-country or true high-elevation work. The surrounding landscape transitions from the more open country west of the unit into steeper drainages and higher ridges eastward.

Water sources are scattered and seasonal despite the drainages that define the unit. Major creeks including Wheeler, Clear, Raspberry, and Toponas flow through timbered valleys and are generally reliable through fall, but spring-fed sources vary by year and location. Eagle Rock Lakes, Lagunita Lake, and the reservoirs (Crowner, Hadley, Yarmany, Chambers) provide known water, though some reservoirs are seasonal.

Springs like Kayser Spring, Split Trough Spring, and Iron Spring exist but aren't always reliable late season. The Colorado River forms the southern boundary but isn't easily accessible for most hunters in the unit. Water management is important—know your creeks and plan access to lakes or springs before hunting specific areas.

Elk are the primary draw, with mule deer and white-tailed deer throughout. Early season favors high parks and timberline areas—glass Long Park and Buffalo Park from ridges and work the edges where timber meets meadow. During rut, bulls move through the rolling terrain connecting parks; Lynx Pass, Yellow Jacket Pass, and ridge saddles are natural gathering points.

Late season pushes elk lower and toward the Colorado River bottom, making the lower creek drainages productive. Mule deer use the rolling timber and parks year-round; glassing ridges morning and evening works well. Pronghorn habitat exists in lower, more open sections west and south.

Moose and bear are possible but secondary. Success requires patience working specific parks and understanding how the rolling terrain channels animal movement.
