About this map

Oracle Junction sits at the nexus of a desert landscape defined by high-elevation drainage systems and the transition between Pinal and Pima counties in the late 1980s. This survey illustrates the intricate network of washes and gulches that channel water through Falcon Valley, including Suizo Wash and Big Wash, which serve as vital topographic markers in this arid environment. The map captures the infrastructure of the era, from a dedicated Roadside Park near the junction to the scattered ranching and utility features like the Small Hill Reservoir and numerous holding tanks.

Industrial and natural history converge south of The Cordones, where a singular Mine Shaft and various Gravel Pits are noted alongside the peaks of the Tortolita Mountains. The settlement at Catalina is shown with its developing street grid, while the presence of the Indian Town Reservoir and Sausaulito Creek near the southern boundary highlights the specific water management patterns essential to this portion of the Arizona desert.
