The Snake River carves a deep path through this 1940s Idaho landscape, defining the agricultural and transport corridor of the region. The map details a sophisticated irrigation network essential for desert farming, featuring the King Hill Main Canal, the King Hill Lateral, and various flumes and siphons that draw water toward the fertile Pasadena Valley. High basalt plateaus like Black Mesa and Jolley Flat overlook the river canyon, while the Oregon Short Line (Union Pacific) railroad follows the river's northern bank. Local life is centered around the Pasadena Valley Sch, and the historical significance of the area is noted at the Pilgrim Stage Sta Historic Site near Big Pilgrim Gulch. This survey captures the mid-century infrastructure of Elmore County before modern expansion, from the springs at Bancroft Springs to the volcanic profile of the Sugar Bowl.
