About this map

The Beaverhead Mountains and Bitterroot Mountains form a massive natural boundary along the Montana and Idaho border, anchoring a landscape of high-altitude basins and significant water management projects. At the southern edge of the survey, the National Reactor Testing Station occupies a portion of the Snake River Plain, marking the era's emerging atomic energy footprint. To the north, engineering feats like the Clark Canyon Dam and Lima Reservoir illustrate mid-century efforts to harness the Red Rock River for regional irrigation and power.

Industrial and agricultural history is visible in the scattered sites of the Nicholia Mine and Tin Cup Mine, as well as the specialized Sheep Experimental Station near Dubois. Transport routes are dominated by the Union Pacific railroad and the north-south corridors of U.S. 91 and U.S. 93. Notable peaks like Borah Peak and Poison Peak define the skyline above remote settlements such as Leadore, Lima, and Goldburg.
