About this map

The international border between the United States of America and Mexico anchors this 1994 survey, capturing the binational character of the Arizona-Sonora frontier. The landscape is defined by the high elevations of the Huachuca Mountains and the Patagonia Mountains, where mining history is preserved at sites like Washington Camp, Duquesne, and the Morning Glory Mine. In the valleys, the Santa Cruz River and San Pedro River provide vital corridors for settlement, supporting communities from Nogales to the small border outpost of Lochiel.

Large land grants such as the Luis Maria Baca Float No 3 and San Rafael De La Zanja indicate early Spanish and Mexican colonial influence on property boundaries. The northern reaches of the map are dominated by the Fort Huachuca Military Reservation, while the western edge reveals the development of Rio Rico and Calabasas. Researchers can also identify the industrial legacy of the region via the Old RR Grade and numerous scattered shafts like the Blue Eagle Mine.
