HD 515 covers the Pryor Mountains in southern Montana along the Wyoming border—an isolated, dramatic limestone-and-dolomite range that rises out of the Bighorn Basin like a fossilized whaleback and feels nothing like the rest of the state. Elevations run from about 3,500 feet on the Bighorn River bottom and the surrounding desert basins to 8,786 feet on East Pryor Mountain, the range high point. The Pryors are unique—a desert-mountain ecosystem with Mojave-feeling juniper-and-mountain mahogany lower slopes, dramatic limestone ice caves and natural ice arches, prehistoric pictograph sites, and a high-elevation top that holds Douglas fir parkland and alpine meadow. Bighorn Canyon National Recreation Area cuts the east side of the range with the Bighorn River reservoir. Mule deer use the timber-juniper transition; mountain lions are abundant; the famous Pryor Mountain wild horses (a small herd of historically distinct mustangs) range the high country—a national rangeland-management debate in slow motion. BLM, Custer Gallatin NF, and the Crow Indian Reservation share the country. Crow tribal land is closed to non-tribal hunters without specific permits—read the FWP HD 515 maps and the reservation boundary very carefully. Access is from MT-310 (the Pryor Mountain road from Bridger over the range and on into Wyoming), the East Pryor Road, and the Crooked Creek and Sage Creek BLM tracts. Bridger has gas and basics; Edgar is tiny; Lovell WY at the south end has services. Cell service is gone in the range. The country is hot in early season and remote—plan for desert conditions even in elk season. The Pryors get less hunting attention than they deserve, in part because of the access complexity, in part because the country looks unwelcoming. The animals are real, the country is unforgettable.
