Area 120 covers the Powder River Basin country south of Buffalo and west of Kaycee—classic central Wyoming sage prairie, broken creek country, and the foothills climbing toward the Bighorn front. Elevations run from about 4,500 feet on the basin floor to 6,500 feet on the higher benches and breaks. The country is rolling sage and bunchgrass prairie with eroded creek-side breaks, scattered ponderosa pine on the higher ridges, and cottonwood ribbons along the Powder River and its tributaries. The Hole-in-the-Wall country in the southern reach—where Butch Cassidy's Wild Bunch holed up—is a recognizable regional landmark. Coal-bed methane and oil-and-gas development is widespread; pumpjacks and lease roads are part of the landscape. BLM, state trust, and significant private ranch share the country with extensive HMA and Walk-In access. I-25 frames the east; county and lease roads thread the basin. Buffalo and Kaycee are the local supply towns; Casper is the larger metro hub south. Cell service is fair on I-25 and reasonable in the developed gas fields. Antelope rifle in October is the bread-and-butter; the open sage holds strong pronghorn density and the broken creek country is where the mature bucks live. Mule deer in the breaks and pine-edge country; whitetail in the river bottoms. Wind blows hard, energy traffic is constant, and the country is bigger than it looks driving I-25.
