2020 Map of Pasadena Valley

About this map

Snake River canyon walls and the surrounding high desert plateaus define this region of Elmore County, where agricultural irrigation networks branch out from the river. The map illustrates a complex system of water management, including the King Hill Lateral, Basin Lateral, and Y Canal, which support the farms and ranches in Pasadena Valley and Swiss Valley. These man-made waterways contrast with the natural drainage of King Hill Cr and Deer Gulch. Large topographical features such as Black Mesa and the Sugar Bowl rise above the valley floor, while natural water sources like Bancroft Springs and Pilgrim Spring are tucked into the drainages. Evidence of human movement and land use is found in the network of local ranch roads, including Old Hwy 30 and Old Oregon Trl, which follow the natural contours of the land.
