Two more large roadless areas remained in the Bighorns as of 1992. It is unknown whether these areas have since been reduced in size by road-building and other development. Both areas straddle the Montana-Wyoming state line, in the northern part of the range. One area, north of U.S. Route 14A and containing the headwaters of the Little Bighorn River, is 155,000 acres of National Forest land. This little-known region features subalpine terrain cut by steep canyons. Pronghorn inhabit the area, as it includes a portion of the Great Plains. What little human use it receives is from hunters and fishermen. The second roadless area is located mainly on the Crow Indian Reservation in Montana; its 144,000 acres also includes 34,000 acres of Devil's Canyon on the Bighorn N.F. in Wyoming. In this part of the range, semidesert prairie is cut by steep canyons leading to Yellowtail Reservoir, and high, Douglas-fir cloaked ridges top out at over 9,000'. Colorful rock formations are common. Rocky Mountain juniper and limber pine are scattered on lower elevations, and wildlife includes pronghorn, rattlesnake, golden eagle, ferruginous hawk, and mule deer. The Crow Indians manage a wild bison herd on this portion of the Bighorns. The Crow lands are a sacred area, and thus are off-limits to non-tribal members.
