About this map

The Snake River defines this landscape, where a sophisticated network of irrigation canals supports agricultural expansion south of Idaho Falls. Engineering feats such as Dam 4672 and Dam 4654 manage the river's flow, feeding the Great Western Canal and Porter Canal to transform the arid surroundings. This 1948 survey shows the city's southward growth, anchored by institutional landmarks like the LDS Temple, Sacred Heart Hospital, and the sprawling Tautphaus Park.

Tracing the Union Pacific rail line reveals the placement of essential community structures, including the New Sweden Sch and the Riverdale Sch (Aban'd). The rural outskirts are marked by small family and community anchors such as the New Sweden Cemetery and Fielding Memorial Cem, illustrating the early 20th-century settlement patterns of Bonneville and Bingham counties before modern suburban development obscured these original property lines and school districts.
