About this map

Challis National Forest dominates this high-elevation landscape in Custer County, characterized by prominent summits and the headwaters of numerous mountain streams. The namesake Twin Peaks serves as a primary landmark, featuring both the Twin Peaks Lookout and a nearby Lookout Cabin. The drainage pattern is well-defined by Challis Creek and Lodgepole Creek, which carve through the terrain beneath peaks such as Corkscrew Mountain and White Valley Mountain.

Access is provided by a network of forest roads including Twin Peaks Road and Challis Creek Road, facilitating movement through the complex topography of gulches like Spruce Gulch and Lang Gulch. The presence of Spruce Gulch Lake and various spring-fed tributaries like Warm Spring Creek highlights the importance of water resources in this portion of the Salmon River Mountains. The map also delineates the boundary between Lemhi and Custer counties along the northern high ridges.
