Unit S77

Key landmarks for navigation and glassing include Green Mountain, Sheep Mountain, and Yarmony Mountain—high points offering long-range visibility into multiple drainages. Gore Canyon itself provides the geographic anchor point. McCord Pass and Gore Pass serve as significant saddles and natural travel corridors.

High-elevation lakes including Twin Lakes, Blue Lake, and Gutzler Lakes mark basin locations and water sources. Piney Ridge and Hartman Divide help orient hunters within the rolling high terrain. Use these features as reference points for planning glassing routes and understanding sheep distribution across drainages.

This is upper-elevation alpine and subalpine terrain ranging from mid-8000s to just under 11,700 feet. Sheep country exists here in steep-sided valleys, rolling ridge systems, and scattered cirque basins with transition zones between dense forest and open tundra. The unit transitions from timbered lower drainages into exposed ridges and peaks where bighorn occupy rocky slopes and alpine meadows.

Coniferous forest dominates lower sections, thinning considerably as elevation increases—expect dense pockets of spruce-fir giving way to wind-scoured ridges where sheep congregate.

Connected road infrastructure via Colorado 134, U.S. 40, Colorado 9, and Colorado 131 means multiple entry points and established trailhead access. Approximately 449 miles of road exists within or bordering the unit, providing fair connectivity to different sections. State Bridge, McCoy, and smaller communities offer staging options.

The rolling complexity and vast ridgeline distance means pressure spreads thin; hunters can find solitude by moving into basin systems and off main drainages. Road access suggests moderate hunter pressure, but sheep terrain's inherent remoteness and climbing difficulty naturally limits actual hunter density.

S77 occupies the Gore Canyon drainage system spanning parts of Grand, Eagle, Summit, and Routt counties. Colorado 134 marks the north boundary, while U.S. 40 and Colorado 9 define the eastern edge along the Blue River corridor. The southern boundary follows Elliott Creek, Hoagland Reservoir, and the Arapaho-White River National Forest edge through Eagles Nest Wilderness, with Colorado 131 closing the unit on the west near State Bridge.

The landscape sits between major highway access points and established mountain towns, placing it in semi-accessible high country.

Despite the 'Limited' water badge, this is sheep country with scattered but reliable water sources critical to the hunt. Major drainages include Beaver Creek, Trail Creek, Sheephorn Creek, Three Licks Creek, and Cottonwood Creek—these valleys provide travel corridors and access into high basins. Springs scattered across higher elevations include Cottonwood Mesa, Mather, Kayser, and Iron Springs.

High-elevation lakes and reservoirs dot the unit; Twin Lakes, Blue Lake, and scattered ponds provide reliability above treeline. Water scarcity at lower elevations makes higher basins key congregation zones for sheep, especially late season.

S77 is exclusively bighorn sheep habitat. Success depends on locating sheep on distant ridges and high basins using optics from strategic vantage points. Spring conditions concentrate sheep around reliable water and emerging vegetation in basins and saddle areas.

Summer finds sheep ranging across high ridges where escape terrain dominates; glass above treeline and along ridge systems. Early-season hunting focuses on high basins and cirques. The terrain's rolling complexity and elevation changes demand physical conditioning and patience—locate sheep through methodical glassing, then plan stalk routes accounting for wind and visible escape terrain.

Water sources and known sheep concentration areas should be prioritized glassing locations.
