2024 Map of Twin Peaks

USGS Topo · Published 2024

About this map

Frank Church-River of No Return Wilderness and the Challis National Forest dominate this high-elevation landscape along the boundary of Lemhi and Custer counties. The terrain is defined by dramatic peaks and deep drainages, centering on the eponymous Twin Peaks and nearby White Mountain. A network of backcountry routes, including the Sleeping Deer Road and Twin Peaks Rd, provide access to this roadless interior where water systems like Warm Spring Creek and Challis Creek originate. High-altitude water bodies such as Spruce Gulch Lake and Twin Cr Lakes are tucked into the steep topography. The presence of Pine Summit and Corkscrew Mtn suggests the difficult navigation required in this part of the Salmon River Mountains, where historical forest service access points like Nat For Dev Rd 86 connect the high ridges to the creek bottoms.
