About this map

Large-scale industrial copper extraction defines the landscape south of Tucson, where the Mission Mine and Pima Mine dominate the northern terrain. This 1981 survey reveals an intricate network of Mine Dumps, Tailings Ponds, and a high-capacity Conveyor system supporting the local mining economy. The map preserves the locations of numerous smaller historical claims, including the Swastika Mine, Paymaster Mine, and Senator Morgan Mine, which are scattered among the foothills of Helmet Peak and Mineral Hill.

Cultural landmarks are sparse but significant, featuring the settlement at San Xavier and the isolated Ruby Star Ranch. Transportation is anchored by Mission Road and the Southern Pacific railroad, which serve the industrial corridor. Local history and genealogy are documented through the presence of the Twin Buttes Cem and smaller sites like the Demetrie area, providing a precise record of human habitation and land use in this desert mining district.
