1948 Map of Idaho Falls North

About this map

The Snake River carves through this late 1940s landscape, serving as the central artery for a complex network of irrigation that defines local agriculture. This survey captures Idaho Falls during a period of post-war expansion, with the city limits reaching toward the Idaho Falls Municipal Airport and the Municipal Golf Course. The density of the canal system, including the Great Western Canal and Osgood Canal, illustrates the intensive transformation of the high desert into productive farmland. Smaller outlying settlements like Coltman, Payne, and Osgood anchor the rural sections, supported by local institutions such as the Coltman Ward Church and Fairview School. The infrastructure of the era is clearly visible, from the Idaho Falls Municipal Power Plant along the river to the Union Pacific tracks and the Yellowstone Highway facilitating regional transport and trade.
