About this map

Ryan Peak and the surrounding high country of the Boulder Mountains dominate this high-elevation landscape along the boundary of Custer and Blaine counties. This terrain serves as a significant hydrological divide, where the headwaters of the East Fork Salmon River flow north, while the North Fork Big Wood River and North Fork Big Lost River drain to the south and east.

The presence of Lost Mine Canyon suggests a history of mineral exploration in these summits, which include notable heights like Glassford Peak and Kent Peak. Protected largely by the Sawtooth National Forest and Challis National Forest, the area is accessed via the Sawtooth National Forest Trailhead, reflecting a landscape defined by deep drainages such as Cougar Canyon and Grave Canyon rather than permanent settlements.
