2024 Map of Sourdough Peak

About this map

Sourdough Peak and the high ridges of Idaho County define this landscape within the Nez Perce National Forest. The map detail captures the remote headwaters of numerous drainages, including Johns Creek and Sourdough Creek, flowing through the protected expanse of the Gospel-Hump Wilderness. Significant topographical landmarks such as Baking Powder Mtn, Blue Ridge, and Dome Hill illustrate the complex verticality of this region. Human presence is sparse, marked primarily by the winding Sourdough Rd and several creek-side survey sections. This map provides a detailed view of the natural water systems that feed the larger river networks, from Taylor Creek in the southeast to Snoose Creek in the northwest, offering a precise look at these drainages before they exit the wilderness boundaries.
