About this map

The Santa Cruz River valley near the Arizona-Mexico border serves as a historic corridor of settlement and preservation in this 1981 survey. At the heart of the map lies the Tubac Presidio State Historical Park, marking the site of the oldest European settlement in Arizona. Further south along the river, the Tumacacori National Monument protects the Spanish colonial mission site near Tumacacori. The landscape is a mix of agricultural river bottom and the rising slopes of the Tumacacori Mountains to the west, where many family-named landmarks such as Kenyon Ranch and El Canto Ranch are situated.

The influence of early 20th-century public works is visible through features like the CCC Dam, while the ruins of Camp Loco suggest more transient habitation in the backcountry. Transportation is defined by the Southern Pacific railroad and the modern highway system, including the Tubac Interchange, which connects these historic sites to the broader region. The eastern portion is dominated by the massive Baca Float No 3 land grant boundary, illustrating the complex history of private and public land ownership in Santa Cruz County.
