2023 Map of Powderhorn Gulch

USGS Topo · Published 2023

About this map

Salmon National Forest defines the eastern reaches of this high-elevation terrain, where steep drainages like Perk Canyon and Dry Canyon descend toward the valley floor. The landscape is characterized by a series of significant watercourses, including Eighteenmile Creek and Clear Creek, which cut through the western slopes. Central to the geography is Center Ridge, a prominent landform that separates the southern drainage of Divide Creek from the northern gulches. Access to this area is maintained through a network of rugged thoroughfares such as Bull Cr Rd and Eighteen Mile Rd, reflecting the remote and topographical nature of this part of Lemhi County. The map provides a detailed look at the drainage patterns of Tenmile Creek and the eponymous Powderhorn Gulch, illustrating the complex hydrology of the region.
