The Yakima River carves through this mid-1960s landscape, defining a fertile valley bounded by the Rattlesnake Hills to the north and Snipes Mountain at its center. This era shows an intricate irrigation network managed by the Bureau of Reclamation, featuring the Sunnyside Canal, Roza Canal, and Snipes Canal, which transformed the arid terrain into a productive agricultural hub. The settlement pattern follows these water lines and the Northern Pacific railroad, connecting towns like Granger, Zillah, and Sunnyside.
