About this map

Snake River canyon walls and the irrigated floor of Pasadena Valley define this mid-century portrait of Elmore County. The landscape preserves layers of western transit history, from the visible tracks of the Oregon Trail winding across the southern plateau to the Union Pacific railroad line following the river's path. Local settlement is anchored by the Pasadena Valley Sch, while the arid surroundings are punctuated by essential water sources like Bancroft Springs and Pilgrim Spr.

High desert topography is prominent, with landmarks such as Sugar Bowl and Black Mesa rising above the valley floor. The map highlights the intersection of early pioneer routes and modern ranching, specifically at the Pilgrim Stage Sta Historic Site. From the depths of Frog Hollow to the broad expanse of Jolley Flat, the survey records a transition from traditional stage stations to an established agricultural community supported by complex canal systems.
