1958 Map of Sahuarita

Genealogists and local historians can trace the early ranching footprint through family names like Johnson Ranch and Mt Fagan Ranch, or locate mining history near Helvetia, where shafts, tunnels, and a Cem are recorded. In the southeastern corner, the terrain transitions into the Coronado National Forest, where the settlement of Greaterville sits near deep drainages like Enzenberg Canyon and Box Canyon. This map preserves the transition from traditional land grants, such as the San Ignacio De La Canoa Grant Boundary, to modern federal research and defense installations.
