About this map

The Idaho Montana Boundary bisects this mid-1960s survey, delineating a high-altitude Divide where the Bitterroot Range separates the two states. This area is defined by its administrative complexity, where the Selway-Bitterroot Wilderness overlaps multiple jurisdictions, including the Bitterroot National Forest, Clearwater National Forest, and Nez Perce National Forest. The landscape is dotted with high mountain basins containing numerous small water bodies such as Tadpole Lake, Frog Lake, and Heinrich Lake.

High points including Blodgett Mountain, Shattuck Mountain, and Frog Peak dominate the topography, connected by primitive transit routes like the Pack Trail. Notable geological features such as Printz Ridge and the Big Flat indicate a landscape of sharp vertical relief. The map documents the drainage patterns of the region's headwaters, featuring Mill Creek, Blodgett Creek, and Sand Creek as they flow from the crest toward the valleys below.
