1905 Map of Patagonia

About this map

Santa Rita Mountains and the Empire Mountains dominate this early 20th-century landscape, which was surveyed when mining and cattle ranching drove the regional economy. The map identifies numerous active operations and claims, including the Total Wreck Mine, Cuprite Mine, and the Helena Mine near Helvetia. A network of family-owned ranching estates, such as Empire Ranch and Lopez's Ranch, are scattered throughout the valleys and foothills, illustrating the settlement patterns of the Arizona Territory just years before statehood. Historical military and transit landmarks appear, including the site of Old Ft Crittenden and the Southern Pacific RR corridor through Sonoita. The inclusion of the Santa Rita Experimental Range and facilities like the Montosa Mill highlight the area's dual role as a center for both mineral extraction and emerging land management research.
