About this map

The Dragoon Mountains dominate the eastern half of this landscape, where the high ridges of the Coronado National Forest meet the desert floor. This area is defined by its deep cultural layers, most notably at Whitehouse Ruins and the archaeological significance of Council Rocks near the mouth of West Stronghold Canyon. These sites hint at a long history of habitation sheltered by the steep granite formations.

Infrastructure in the early 1970s is concentrated in the western lowlands, where the Southern Pacific railroad passes through the settlement of Tully. The map documents a rugged cattle-ranching and mining economy, evidenced by Horse Ranch and the presence of several Prospect sites and a Quarry. Water remains the primary concern for the inhabitants of this arid region, as shown by the network of scattered Jeep Trails connecting remote sites like Little Spring and Packard Tank across Slavin Wash.
