Rattlesnake Hills dominate the northern landscape of this Yakima County region, where the terrain drops sharply into a complex network of irrigation infrastructure and agricultural tracts. This mid-1960s survey documents a highly managed water system essential to the arid Yakima Valley, featuring the Roza Aqueduct, Roza Canal, and Sunnyside Canal. These engineered waterways cut across the lower elevations, supported by a Pumping Station and a Siphon to move water through the valley.
