1958 Map of Idaho Falls

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.
