Abstract

The Selway-Bitterroot Wilderness covers about 1.25 million acres in east-central Idaho and western Montana (fig. 1). The wilderness lies across the Bitterroot Range, which forms the boundary between Idaho and Montana, and includes large portions of the drainages of the Selway, Lochsa, and Bitterroot Rivers. Elevations range from 1,800 ft on the Selway River near the wilderness boundary to 10,157 ft at Trapper Peak in the Bitterroot Mountains. Cities within 50 min of the wilderness include Missoula, Hamilton, and Salmon on the east, and Orofino and Grangeville on the west. Access to trailheads near the edge of the wilderness is limited to dirt roads.
