1979 Map of Sagebrush Ridge

About this map

Sagebrush Ridge dominates the northern landscape of this interior Washington territory, where the arid uplands meet an intricate network of late-century irrigation infrastructure. The terrain is marked by the deep cut of Black Canyon and the natural bottleneck of The Gap, features that stand in contrast to the engineered water systems below. The southern portion of the sheet reveals the vital importance of water management in the Yakima Valley region, defined by the Roza Canal and Snipes Canal, which support localized agriculture and ranching operations like the Anderson Ranch. The map captures a transition from high-desert ridge lines to a developed valley floor, where several Gravel Pits and a Landing Strip indicate mid-century industrial activity and regional accessibility. A network of family-named thoroughfares, including Hamilton Road and Evans Road, provides a clear view of the rural settlement patterns established by the late 1970s.
