1942 Map of Oro Blanco

USGS Topo · Published 1968

About this map

Mining operations and ranching outposts define this rugged corner of the Arizona Sonora border during the early 1940s. The landscape is dominated by the San Luis Mts and Cobre Ridge, where a network of canyons like Agua Cercada Canyon and Warsaw Canyon provided the challenging setting for the region's extraction industry. The map captures the settlement of Oro Blanco and several ranching sites, including Garcia Ranch and Tres Bellotas Ranch, which serve as evidence of early 20th-century habitation in this arid terrain.
