2017 Map of Saint Joseph Peak

About this map

Saint Joseph Peak and Bass Peak anchor the high-altitude topography of the Bitterroot Mountains along the jagged border where Montana meets Idaho. This high-country terrain is defined by its dramatic drainage networks, with numerous alpine water bodies like Sweeney Lake, Bass Lake, and Storm Lake feeding the headwaters of the Bitterroot River watershed. The map illustrates a complex of protected lands, including the Lolo National Forest, Bitterroot National Forest, and Clearwater National Forest, showing how these vast tracts of wilderness converge. Significant mountain crossings like Stormy Pass and prominent summits such as the Heavenly Twins mark the skyline, while several forks of Kootenai Creek carve through the deep glacial valleys. This survey captures the pristine character of the northern Rockies, documenting the precise boundary between Idaho County and Ravalli County as it follows the continental divide.
