About this map

Thompson Pass serves as a critical high-altitude crossing along the Montana Idaho border, where the Bitterroot Range separates Shoshone and Sanders counties. The landscape is defined by the intersection of three major protected areas: the Kanisku National Forest, Lolo National Forest, and Coeur d'Alene National Forest. This high-country drainage system is marked by alpine features such as Revett Lake, the Blossom Lakes, and Pear Lake, which feed into steep canyons like Military Gulch and Bear Gulch.

Transportation through these summits relies on historic routes including State Hwy 4 and Prospect Creek Rd. The presence of several high passes, including Glidden Pass and Burke Summit, indicates the historical importance of this corridor for regional movement across the panhandle. The drainage of the Little N Fork S Fork Coeur d'Alene River highlights the complex hydrology of the Coeur d'Alene Mountains, providing a detailed look at the geographic spine of the northern Rockies.
