About this map

The Snake River carves a winding path through the basalt and sagebrush landscape of Elmore County, defining the agricultural and topographical character of this southern Idaho region. Irrigation infrastructure is central to the area's development, evidenced by the sophisticated network of the Basin Lateral, King Hill Lateral, and the Y Canal that feed the surrounding flats and valleys. The settlement of Pasadena Valley sits within this irrigated corridor, supported by a grid of rural roads such as S Carnahan Rd and Frog Hollow Rd.

Beyond the green valley floors, the terrain rises sharply to the expansive Black Mesa and distinctive volcanic landmarks like the Sugar Bowl. These higher elevations, including Jolley Flat and Swiss Valley, contrast with the riparian zones near Bancroft Springs and Pilgrim Spring. The map also captures the path of Old Hwy 30, tracing the historical transit routes that preceded modern interstate travel through the Snake River canyon.
