About this map

The Snake River and its intricate canal systems define the agricultural heart of this Eastern Idaho region during the late 1970s. This survey details the complex water management network essential to the valley, including the Aberdeen Canal, Peoples Canal, and Reservation Canal. To the west, the landscape shifts abruptly into the volcanic terrain of Hells Half Acre and the expansive Idaho National Engineering Laboratory site, where the small settlement of Atomic City sits on the edge of the basalt flows.

Industrial and institutional landmarks anchor the settlements, from the large Gay Mine in the east to the State Hospital South in Blackfoot. The Fort Hall Indian Reservation encompasses much of the southern portion of the map, where the Portneuf River meets the American Falls Reservoir. Along the Union Pacific rail line, established agricultural hubs like Shelley, Firth, and Basalt mark the historic transport corridor through the valley.
