2020 Map of Cape Horn Lakes

About this map

The Middle Fork Salmon River carves through the northwestern corner of this high-elevation terrain, part of a protected wilderness corridor at the border of Valley and Custer counties. This landscape is defined by its extensive network of glacial tarns and alpine basins, including the clustered Mable Lakes, Lola Lakes, and Finger Lakes. The topography rises to prominent summits such as Ruffneck Peak and Cape Horn Mtn, while the interior is drained by a complex system of waterways like Marsh Creek and Beaver Creek. Human impact is represented primarily by isolated forest routes such as Seafoam Rd and the Lola Creek Campground Rd. The mapping of the Middle Fork Salmon Wild and Scenic River corridor highlights the transition between the Boise and Challis national forests, documenting a preserved backcountry environment in the early twenty-first century.
