Edit
Area 108 covers the central high country of the Bighorn Mountains—the heart of the range including the eastern flank of Cloud Peak Wilderness, the Powder River Pass country, and the high timber and meadow belt straddling the crest. Elevations run from about 7,000 feet on the lower forest benches to over 12,000 feet on Cloud Peak (13,171, the highest point in the Bighorns) and the surrounding alpine country. The Cloud Peak Wilderness covers about 189,000 acres of glaciated high country: cirques, alpine lakes (more than 250 of them), boulder fields, persistent snowfields, and timbered drainages full of lodgepole pine, Engelmann spruce, and subalpine fir. Below the wilderness boundary, the high parks and meadows hold elk through the rut and after, and the lodgepole-spruce-fir mosaic provides classic Rocky Mountain elk habitat.
Bighorn National Forest and the Cloud Peak Wilderness dominate. US-16 over Powder River Pass is the paved spine; forest roads off it reach trailheads. Buffalo, Ten Sleep, and Sheridan are the supply towns. Cell service drops past town. Pack-in for the wilderness core; truck-camp hunting works for the lower timber and meadow country. Quality elk and mule deer, with bighorn sheep on the high cliffs. Snow shuts the high country and Powder River Pass by mid-October most years. The Bighorns at altitude are weather of their own—plan for winter conditions.

Recent Trophy Scores · 2020–2025
Trophy score data is tracked by county, so the overlap with GMU boundaries is approximate. These numbers tell you whether the area is capable of growing big animals — they do not indicate public vs. private land. Big elk can come from anywhere; most elk in the lower 48 trace back to Yellowstone stock that was transplanted west after the species was nearly extirpated in the early 1900s.
