1990 Map of Ajo South

About this map

The New Cornelia Mine dominates the northern landscape of this region, a massive open-pit operation defined by its extensive Mine Dump, Concentrator Hill, and the South Dam Tailings Pond. This industrial footprint sits immediately south of Ajo, where the Curley Sch serves as a central landmark for the town's residential core. Beyond the mine's edge, the terrain shifts abruptly into the jagged peaks of the Little Ajo Mountains, featuring distinctive formations like Locomotive Rock and the high summit of Black Mountain. To the east and south, the topography flattens into The Ajo Valley, a desert expanse marked by ephemeral watercourses such as Cuerda de Leña and Gunsight Wash. The presence of numerous Check Dams and livestock watering points like Eberling Tank reveals the efforts to manage scarce water resources in this arid Pima County environment.
