1938 Map of Borah Peak

USGS Topo · Published 1938

About this map

Borah Peak dominates the high country of the Lost River Range in this mid-1930s survey of Custer and Lemhi counties. The landscape transitions from the jagged heights of Leatherman Peak and Dickey Peak down to the expansive Thousand Springs Valley, where the Big Lost River and Thousand Springs define the local hydrology. The area is characterized by a network of high-altitude passes such as Doublespring Pass and Horseheaven Pass, connecting the valley floor to the remote interior of the Salmon National Forest.
