Edit
Area 66 covers the country south of Lander between the southern Wind River Range foothills and the Red Desert—a dramatic transition zone where the granite of the Winds gives way to the sage-steppe basin country running south toward the Continental Divide. Elevations run from about 6,000 feet in the basin to over 10,000 feet on the higher Wind River foothills and the granite escarpments around South Pass and Atlantic City. The country is varied: sage and bunchgrass on the basin benches, mountain mahogany and aspen on the foothill breaks, lodgepole and spruce-fir on the higher Wind River ridges, and the legendary granite outcrop country around the Sweetwater Rocks and South Pass. The Sweetwater River cuts through with cottonwood bottoms; Beaver Creek and Twin Creek drain the foothills. BLM dominates the lower country, Shoshone NF covers the higher Wind River flanks, and significant private ranch fills in the foothills and along the Sweetwater. WY-28 (the South Pass Highway) and US-287 frame the access; the dirt road network out toward Atlantic City and South Pass is extensive but rough. Lander is the supply town—gas, the Lander Bar, real grocery, the City Park—and Atlantic City is the historic mining ghost-town with one tavern and a lot of character. Cell service drops past town. Mixed-species hunting is the hallmark: elk in the timbered foothills (some held over from feedground influence), mule deer in the mahogany breaks and aspen pockets, antelope on the open sage. The country glasses for miles.

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.
