About this map

Mount Jefferson stands as the prominent height in this 2014 survey, marking a significant point along the Continental Divide where the borders of Montana and Idaho converge. This high-altitude landscape is defined by the massive crest of the Eastern Centennial Mountains, separating the drainages of the Beaverhead National Forest to the north from the Targhee National Forest to the south.

The map reveals a network of vital mountain passages, including Red Rock Pass and Snoo-weh Pass, which have served as critical transition points between the Centennial Valley and the high basins. Water features are abundant despite the elevation, with named sources like Keg Spring, Fruin Spring, and Horsemint Spring feeding into Hell Roaring Cr and Red Rock Cr. Remote landmarks such as Alaska Basin and Nemesis Mtn illustrate the complex topography of the Rock Creek Basin area, providing a precise look at the drainage patterns and land boundaries of Beaverhead and Fremont counties.
