Edit
Area 104 covers the country around Powell in the northern Bighorn Basin—heavily agricultural country running between the Shoshone River and the Wyoming-Montana line, with the Heart Mountain area on the western edge and irrigated farmland dominating most of the unit. Elevations run from about 4,200 feet along the Shoshone to 5,500 feet on the surrounding sage benches. The country is mostly irrigated ag: sugar beets, malt barley, alfalfa, dry beans, and corn on the wheel-line and pivot ground, with cottonwood-and-willow bottoms along the Shoshone and the irrigation canals and dry sage benches between the cultivated fields. The Heart Mountain WWII Japanese-American internment site is preserved on the western edge—the country has more history than the empty horizon suggests. Polecat Bench and the surrounding badlands break the cultivated monotony in places.
Mostly private ag and ranch ground with thin scatters of BLM and state. The HMA and Walk-In programs open critical access on private—without them this is a tough unit to hunt because the public ground is genuinely sparse. US-14A and county roads thread the country. Powell is the supply town—gas, motels, real grocery, the Northwest College campus—and Cody is 30 minutes west for any larger needs. Cell service is fair throughout. Whitetail dominate the river bottoms and irrigated edges; antelope work the open sage and stubble fields; mule deer use the badland breaks. The country is genuinely good for whitetail by Wyoming standards.

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.
