1979 Map of Cerro Colorado

About this map

Mining operations and ranching outposts define this arid landscape in Pima County, captured during a period of active land use in the late 1970s. The Cerro Colorado Mountains and Las Guijas Mountains dominate the terrain, where numerous small-scale mining sites like the Liberty Mine and Silver Hill Mine are scattered across the slopes. Water management is central to survival here, evidenced by a network of catchments such as Rincon Tank and Bolas Blancas Wash, along with an Aqueduct system cutting through the valley floor.
