1979 Map of Cumero Mtn

About this map

San Luis Mountains and the international border between the United States and Mexico define this high-desert landscape in the late 1970s. The topography is dominated by the jagged rise of Cumero Mtn and Lesna Peak, where water sources are the critical markers of human presence. Named water features like Marihuana Tank, Slick Rock Tank, and Alamito Tank are scattered throughout the Coronado National Forest, illustrating the necessity of water management in this arid cattle-country environment. Traces of ranching life and early habitation appear at the Garcia Ranch, which is accompanied by a nearby Cem (cemetery). Evidence of mineral exploration persists at a small Prospect near Cerro del Fresnal, while a network of jeep trails connects isolated points like Coches Windmill and the Cantina Reservoir near the border of Pima County.
