2017 Map of Diamond Peak

About this map

Diamond Peak dominates the southern landscape of this 2017 survey, marking a high point within the Lemhi Range at the intersection of significant public lands. The terrain is defined by a dense network of drainages and canyons, including Sawmill Canyon and Rocky Canyon, which reveal the complex topography where the Targhee National Forest and Challis National Forest meet. The map documents the boundary between Lemhi and Butte Counties, following the ridgeline through areas such as Little Sawmill Canyon and Kaufman Gulch. Water features like Badger Cr and N Fork Pass Cr flow through the eastern slopes toward the Birch Creek Valley. This record of the high country provides a precise view of the federal land divisions and the named geographic features that have guided travelers and land managers through this part of Idaho for generations.
