About this map

The Snake River corridor anchors this mid-century look at eastern Idaho, where irrigation networks like the Idaho Canal and Aberdeen Canal enabled the growth of Idaho Falls and Blackfoot. This era is defined by the stark contrast between the fertile river valley and the expansive volcanic landscapes of Craters of the Moon National Monument. The map documents a significant industrial and scientific period, notably featuring Atomic City on the lava plains.

Mineral extraction in the high country is well-represented by the White Knob Mine and Empire Mine in the north, while the Union Pacific railroad lines link agricultural centers such as Shelley and Arco. For genealogists, the map preserves the locations of early religious and social hubs, including St Marys Mission and the Fort Hall Indian Reservation. The terrain is punctuated by distinctive volcanic features like Big Southern Butte and the oddly named Invisible Mountain, alongside early water management sites like the Mackay Reservoir and American Falls Reservoir.
