1948 Map of Idaho Falls South

About this map

The Snake River corridor south of Idaho Falls is defined by a sophisticated gravity-fed irrigation network that transformed the high desert into a productive agricultural valley. A dense web of canals, including the Great Western Canal, Porter Canal, and Idaho Canal, fans out across the landscape, illustrating the region's total reliance on water engineering for its development. The settlement pattern follows this infrastructure, with local landmarks like New Sweden Sch and Stanton Sch serving dispersed farming families.
