1936 Map of American Falls

About this map

American Falls Reservoir dominates the landscape of this 1930s Idaho survey, created by the U.S. Bureau of Reclamation and the Geological Survey to document the newly harnessed Snake River. The American Falls Dam stands as the focal point of local engineering, supporting a growing regional infrastructure that includes the State Fish Hatchery and the Agricultural Experiment Sta near Aberdeen. Transportation through the high plains is defined by the Union Pacific railroad and the Old Oregon Trail Highway, which trace the southern contours of the water.
