1997 Map of Lost Trail Pass

USGS Topo · Published 2002

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.
