About this map

The agricultural heart of the Upper Snake River Valley comes into focus through this late-1940s survey of the St. Anthony vicinity. Centered on the confluence of Henrys Fork and the Teton River, the map reveals an intricate network of gravity-fed irrigation canals, including the St. Anthony Canal, Last Chance Canal, and Egin Canal. These waterways define the Egin Bench, where the transition from river bottom to plateau supported a dense arrangement of family farms and small settlements like Wilford and Twin Groves.

Transportation and institutional life are anchored by the Union Pacific railroad and the Yellowstone Highway, which provided vital links for the regional economy. Beyond the municipal centers of Teton and Sugar City, notable landmarks include the Idaho Industrial Training School and the Fairgrounds on the outskirts of the county seat. This map captures the region at a peak of traditional agricultural development, prior to the large-scale reservoir projects that would later alter the local hydrology.
