1988 Map of Oracle Junction

USGS Topo · Published 1989

About this map

Oracle Junction serves as the focal point of this late 1980s landscape at the boundary of Pinal and Pima counties. The area is defined by a complex drainage system flowing through Falcon Valley, where numerous washes like Big Wash and Suizo Wash cross the desert floor between the Falcon Divide and The Cordones. The settlement of Catalina shows established street grids in the southern portion of the sheet, reflecting the suburban expansion into the desert north of Tucson. High-tension infrastructure is prominent throughout, marked by transmission lines and a Substation.
