1988 Map of Thompson Pass

About this map

Thompson Pass marks the high point of the Bitterroot Range crossing on this 1980s-era topographic survey, which documents the rugged border between the Shoshone and Sanders counties. The landscape is defined by its intense alpine topography and mining heritage, evidenced by numerous Prospect and Prospects scattered across the Coeur d'Alene, Kaniksu, and Lolo national forests. This area serves as a critical watershed, where the headwaters of the Little North Fork South Fork Coeur d'Alene River begin their journey west into Idaho. Distinctive high-altitude basins hold Revett Lake, Blossom Lakes, and the paired Upper Glidden Lake and Lower Glidden Lake, providing a clear look at the glacial geography along the Idaho-Montana state line before modern development altered these remote access points.
