About this map

The Santa Rita Mountains define this landscape, where mining activity once centered around the Helvetia townsite. By the early 1980s, the area remained a network of historic claims and operational remains, including the Helvetia Cem and numerous named prospects like the Bulldozer Mine and Gunsight Mine. The northern half of the map is dominated by the Santa Rita Experimental Range and Wildlife Area, illustrating a transition from extractive industry to land management and conservation.

To the south, the terrain descends toward Greaterville, another notable node of local activity near the Coronado National Forest boundary. Deep drainages such as Box Canyon and Sawmill Canyon cut through the high desert, leading to essential water sources like Shamrod Spring and Enzenberg Well. The concentration of sites like the Florida Work Center and the Radio Facility suggests the area's continued importance for forestry and communications infrastructure during this period.
