Blacktail Mountains dominate the northern landscape of this Beaverhead County region, where high-altitude drainages carve a complex network of canyons and creeks. This 2020 survey documents the intersection of several significant watercourses, including the headwaters of Beech Cr and Crooked Cr, which define the local topography. The map illustrates a high-country environment where narrow corridors like Ashbough Canyon, Riley Canyon, and Jake Canyon provide natural passages through the terrain.
