About this map

The Santa Rita Experimental Range and its network of observation towers dominate the central landscape of this Pima County survey. To the north, the Bombing and Gunnery Range extends across the desert floor, featuring a prominent landing strip and markers for a military reservation boundary. The western edge of the map is anchored by the Santa Cruz River, where the Southern Pacific railroad parallels the Tucson-Nogales Highway, connecting the agricultural and rail hubs of Sahuarita and Continental.

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.
