About this map

Sourdough Peak and its surrounding ridgelines dominate this portion of the Nez Perce National Forest in central Idaho. The landscape is defined by a dense network of high-elevation drainages including Johns Cr, Sourdough Cr, and the W Fork Twentymile Cr. Prominent terrain features such as Blue Ridge, Bull Elk Ridge, and Bear Grass Ridge reflect the high-country character of the region.

Evidence of recreational and forest management activity is centered at the Sourdough Saddle Campground, located near the peak itself. The map provides a detailed view of the complex topography between Baking Powder Mtn and Dome Hill, illustrating the intricate headwaters of streams like Aubion Cr and Open Cr. This survey documents the roadless and mountainous nature of the Nez Perce backcountry as it remained in the early 21st century.
