1978 Map of Devils Teeth Rapids

About this map

The Salmon River carves a deep path through the wilderness of central Idaho, marking a distinct boundary between the Bitterroot National Forest and the Payette National Forest. This 1978 survey highlights the treacherous water features that define this reach, most notably the Devils Teeth Rapids and Little Devils Teeth Rapids. The landscape is dominated by steep terrain and named ridgelines such as Thirsty Ridge and Prospect Ridge, with the river serving as the primary corridor of movement through the Idaho Primitive Area. Human presence is minimal, recorded primarily as isolated points like the Patrol Cabin and the Campsite Corey Bar near Black Canyon. The network of Pack Trails winding through Basin and past Grass Mountain indicates the area's use for backcountry patrol and recreation during the late 1970s, well before modern infrastructure reached these interior breaks.
