About this map

Diamond Peak and the high ridgelines of the Lemhi Range dominate this mid-century survey of the Challis National Forest and Salmon National Forest. The landscape is a study in verticality and water management, where numerous drainages like Badger Creek and Eightmile Canyon Creek descend from the summits toward the valley floor. Evidence of the region's mining history is scattered throughout the canyons, notably at the Badger Mine and the Valley View Mine, alongside several unnamed prospects and tunnels that point to early 20th-century exploration.

Lower elevations near the Big Lost River show the thin footprint of human activity at the small settlement of Clyde. Essential infrastructure of the era, such as a Gaging Sta and a small Cem, are situated along the roads that skirt the mountain base. The transition from the high peaks of Bell Mountain down to the alluvial flats of Sunny Bar illustrates a classic Basin and Range environment before the advent of modern development.
