About this map

Mt Jefferson and the Eastern Centennial Mountains dominate this high-altitude landscape along the border of Montana and Idaho. The territory is defined by the Continental Divide, which traces a high ridge through the Beaverhead National Forest and Targhee National Forest. This high-country drainage system feeds into Red Rock Cr and the low-lying Centennial Valley, where the Red Rock Lakes National Wildlife Refuge provides a protected sanctuary in the Alaska Basin.

Logistics in this remote terrain are marked by established passes and springs essential for travel, including Snoo-weh Pass and Red Rock Pass. Hikers and surveyors can trace the Continental Divide National Scenic Trail as it winds through Hell Roaring Canyon and past Nemesis Mtn. High-elevation water sources like Blair Lake, Lillian Lake, and Horseman Spring highlight the critical water geography of these peaks.
