The Lewis and Clark National Historic Trail follows the high ridgelines of the Bitterroot Mountains in this 1990s revision, tracing a path through the heart of Clearwater National Forest. This remote backcountry landscape is defined by its dramatic drainage systems, where Cayuse Creek and its numerous tributaries like Potato Creek and Gravey Creek carve through the Idaho wilderness. Evidence of forest management and backcountry travel is visible through a network of established paths, including the North Fork Powell Trail and the Ranger District Trail. Notable high points like Moccasin Peak, Lunde Peak, and the distinctively named Devils Chair serve as natural landmarks. Further south, the map identifies specific backcountry sites such as Saddle Camp and Howard Camp, providing critical spatial context for the area's recreational and administrative history within the Clearwater and Idaho county borderlands near Horseshoe Lake.
