About this map

The Lemhi Range rises steeply in the southwestern corner of this Idaho study, where the Salmon National Forest boundary protects the high-altitude watershed of the Nez Perce Creek. This high-desert landscape is defined by its vital water sources, including the namesake Purcell Spring, Warm Springs, and Cold Spring, which provide critical moisture to an otherwise arid terrain. The drainage patterns are clearly established by Texas Creek and Eighteenmile Cr as they move toward the broader Lemhi Valley.

A network of remote access routes such as Texas Creek Rd and Nat For Dev Rd 212 crisscross the valley floor, connecting the scattered springs and gulches. To the south, Nez Perce Lake sits tucked near the forest edge, while distinctive landforms like Mid Ridge and Big Dry Gulch shape the topography of the Lemhi County backcountry. The map illustrates a landscape of high-elevation transitions, from the mountain peaks to the alluvial fans of the valley.
