1958 Map of Campini Mesa

About this map

The international border between the United States and Mexico forms the southern boundary of this high-desert survey, where the peaks of the Coronado National Forest meet the flat expanse of Campini Mesa. In the late 1950s, this landscape was defined by isolated livestock operations and the seasonal drainage of deep canyons. The map records several named cattle operations, including Bercich Ranch and Lone Mountain Ranch, which were essential to the region's ranching economy. The complex topography is carved by a network of dry washes and canyons, such as Sunnyside Canyon and School Canyon, while Joaquin Creek provides a rare indication of water flow. The presence of the Black Tail Canyon Spring and a remote Water Tank highlight the critical nature of water resources for sustaining life and industry along this remote stretch of the Arizona-Sonora borderlands.
