About this map

Mining operations and cattle ranching define this high-desert landscape along the international border in the late 1940s. The Patagonia Mountains dominate the western terrain, where a cluster of historic workings including the Worlds Fair Mine, Humboldt Mine, and Morning Glory Mine speak to the region's mineral wealth. Nearby, the settlements of Harshaw, Washington Camp, and Duquesne serve as focal points for local commerce and education, the latter featuring the Duquesne Sch.

To the south, the village of Lochiel sits directly against the United States Mexico boundary line, marked by Monument 121 and a Custom House. East of the mountains, the terrain softens into the San Rafael De La Zanja land grant, where the Santa Cruz River flows through a valley dotted with family rangelands like the Heady Ashburn Ranch and McPherson Ranch. This survey captures a moment when frontier ranching and industrial mining remained the primary drivers of the local economy.
