1979 Map of Cumero Mtn

About this map

Coronado National Forest dominates this borderlands landscape, where the jagged peaks of the San Luis Mountains overlook the international boundary between the United States and Mexico. The rugged terrain is marked by essential water infrastructure required for ranching and mining in the desert, including the Marijuana Tank and Cantina Reservoir. Small-scale industrial history is evident at the Sandwash Mill and a nearby Prospect, while the Garcia Ranch and an adjacent Cem signify the localized settlement and family history of this remote Pima County corridor. The map details a network of canyons and washes, such as Coches Canyon and Arrieta Wash, which served as natural conduits through the high desert during the late 1970s.
