Edit
Area 107 covers the dramatic western escarpment of the Bighorn Mountains around Hyattville and the Medicine Lodge area, climbing from the Bighorn Basin floor up to the Bighorn high country. Elevations run from about 4,500 feet on the basin benches to over 10,000 feet on the high Bighorn ridges. The escarpment is steep and dramatic—the Bighorns rise abruptly out of the basin and the country gains 5,000+ feet of elevation in a few miles. Vegetation stratifies hard: sage and bunchgrass on the lower benches, mountain mahogany and juniper on the rocky shoulders, transitioning through Douglas fir and limber pine into lodgepole and spruce-fir on the upper slopes, with alpine country on the highest ridges. Medicine Lodge State Archaeological Site preserves significant petroglyph and pictograph panels and is worth a visit. Paint Rock Creek and Medicine Lodge Creek drain the country.
Bighorn NF covers the upper country, with BLM and significant private ranch in the foothills. Forest roads off US-16 provide access; the Hyattville-area county roads climb into the foothills. Hyattville is tiny—a post office and not much else; Worland is the full-service supply town and Manderson is closer. Cell service drops fast. Quality elk in the upper timber for those who draw, mule deer in the mahogany breaks and lower forest, antelope on the basin benches. The country is overlooked and pressure stays low.

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.
