About this map

The Continental Divide zigzags across this high-altitude landscape, defining the rugged border between Idaho and Montana in the late 1950s. Mining activity is prominent throughout the Lemhi Range, with operations such as the Copper Queen Mine, Maryland Mine, and Tinkers Mine clustered near Leadore. The region is a patchwork of federal lands, including the Salmon National Forest, Challis National Forest, and Targhee National Forest, showcasing a complex system of resource management through various ranger stations like Mahogany and Bell Mountain.

Transportation corridors follow the natural valleys, with the Union Pacific Railroad and U. S. 91 paralleling the Beaver Creek drainage toward the pass at Monida. In the lower elevations to the southeast, the agricultural and scientific landscape appears around Dubois, featuring the Sheep Experimental Station and the waters of Mud Lake. Prominent summits like Borah Peak and Leatherman Peak dominate the western horizon, anchoring the topography of the Lost River Range.
