About this map

Clark Ridge and the Continental Divide define this high-elevation meeting point of three national forests and two states in the late 1990s. The map centers on the critical mountain passes of Lost Trail Pass, Chief Joseph Pass, and Gibbons Pass, which have served as essential conduits for travel across the Montana and Idaho border for centuries. The convergence of the Bitterroot, Salmon, and Beaverhead National Forests underscores the area's significance as a federally managed wilderness corridor.

Evidence of early exploration and Native American movement is preserved through the Lewis and Clark National Historic Trail and the Nez Perce (Ne-Me-Poo) National Historic Trail. While the landscape is dominated by drainages like the North Fork Salmon River and East Fork Camp Creek, small-scale resource extraction is noted at several prospects along the ridges. The survey also traces the modern Continental Divide Scenic Trail as it winds through high points like Saddle Mountain.
