1962 Map of Lem Peak

About this map

Lem Peak towers over the surrounding landscape of the Salmon National Forest, marking a high point in this 1962 field-checked survey of Lemhi County. The map provides a look at the historical geography of the region, notably tracing the Old Indian Treaty Boundary as it cuts across the northern ridges near Lang Ridge and First Basin. The terrain is defined by a dense network of drainages and basins, where Basin Creek flows toward Hayden Basin and the high-altitude Buck Lakes rest below the summit.
