About this map

Diamond Peak dominates this high-altitude landscape within the Lemhi Range, marking a dramatic topographical intersection where the Targhee National Forest and Challis National Forest meet. The terrain is defined by a series of steep drainages and erosional features, including the sprawling Sawmill Canyon and Bighorn Canyon. These canyons feed toward the Birch Creek Valley to the east, illustrating the complex watershed system of the region with named tributaries such as N-Fork Pass Cr and Badger Cr.

Access to this remote interior is documented via primitive routes like Sawmill Canyon Rd and Ramshorn Rd. The map provides a precise look at the 2013 boundary lines between Lemhi and Butte counties, showing how the jurisdictional divide follows the high ridges. This survey is particularly useful for those studying the intersection of federal forest lands and the natural geological formations that define the eastern Idaho wilderness.
