2013 Map of Cape Horn Lakes

About this map

Challis National Forest and Boise National Forest meet in this high-elevation landscape, where the headwaters of the Middle Fork Salmon River begin to take shape. The terrain is defined by a dense network of alpine water bodies, including Langer Lake, Island Lake, and the remote Cape Horn Lakes. The intersection of Marsh Creek and Beaver Creek provides a focal point for backcountry recreation, marked by established sites such as the Beaver Creek Campground and Lola Creek Campground. Historically significant transit and pack points are evident at the Marsh Creek Transfer Camp, while peaks like Ruffneck Peak and Cape Horn Mtn overlook the numerous drainages that feed the Salmon River system. The map also delineates the boundary between Valley and Custer counties, tracing the crests and creek beds that separate these two wilderness-rich regions.
