About this map

Mining operations and cattle ranching dominate this borderlands landscape, where the southern boundary of the Coronado National Forest meets the Arizona-Sonora international line. The western hills are densely populated with industrial sites such as the World Fair Mine, The Mowry Mine, and Belmont Mine, reflecting an era of intense mineral extraction near the settlements of Washington and Duquesne. These mining camps once supported hundreds of residents in the Patagonia Mountains before production slowed.

To the east, the terrain transitions into the wide valleys of the San Rafael de la Zanja land grant, home to the Cananea Land & Cattle Co. (Egans) Ranch and Lochiel. The Presence of a Camp of Troops and a double wire fence along the border highlights the strategic military and customs importance of the region in the early twentieth century. Family-named landmarks like Stevensons Ranch and Martins Ranch dot the headwaters of the Santa Cruz River, mapping a distinct geography of ranching life.
