About this map

The newly engineered Blackfoot River Reservoir dominates this landscape in the years following its 1914 completion, held back by the Blackfoot Dam in the north. This survey, conducted between 1910 and 1914, captures a transitional period for the high-altitude ranching country of eastern Idaho. Small outposts and family-owned properties such as Perkins Ranch, Clements Ranch, and Doutts Ranch are scattered across the terrain, indicating a sparse but established pastoral economy.

Transport through the valley relies on historic routes like the Soda Springs Road and Bray Road, with the Blackfoot Bridge providing a critical crossing point south of the reservoir. To the east, the Aspen Range rises sharply, while the volcanic dome of China Hat stands as a prominent landmark on the valley floor. Water sources are vital here, from the steady flow of the Blackfoot River to smaller landmarks like Chub Springs and Warm Spring, which provided essential resources for early settlers and their livestock.
