About this map

The Continental Divide serves as a natural and political boundary on this map, marking the border between Idaho and Montana where Idaho Co and Montana’s Ravalli Co meet. This high-altitude landscape is defined by its extensive network of mountain lakes and steep drainages, managed across the Lolo National Forest, Clearwater National Forest, and Bitterroot National Forest. Several prominent summits anchor the terrain, including Saint Joseph Peak, Bass Peak, and the Heavenly Twins.

Water plays a central role in the geography of this quadrangle, with numerous high-country basins feeding into Kootenai Creek, Bass Creek, and S Fork Lolo Creek. From Moose Lake in the northwest to Saint Mary Lake in the southeast, the map documents a series of glacial lakes including North Kootenai Lake, Middle Fork Lakes, and Grimes Lake. Significant mountain crossings are also identified, such as Stormy Pass near the southern border, which provides passage between the drainages of S Fork Storm Creek and Beaver Creek.
