About this map

The Continental Divide serves as the high boundary between Idaho and Montana in this mid-century survey of the Beaverhead Mountains. This landscape is defined by the broad Birch Creek Valley and the steep eastern face of the Lemhi Range, where the mining history of the region is evident at the Hahn (Site) and various Prospects scattered through the canyons. The presence of Kilns and the Old RR Grade Trail suggests the area's industrial past, likely supporting the smelting operations once active in the vicinity of Nicholia.

A network of springs, such as Slaughterhouse Spring and Cool Kiln Spr, provided essential water in this high-altitude environment. Transport through the region follows established corridors like the Lemhi Union Road and crosses Gilmore Summit. The map also delineates the extensive boundaries of the Challis National Forest, Targhee National Forest, and Salmon National Forest, highlighting the area's transition into protected wilderness.
