About this map

Patagonia Lake State Park and the surrounding high desert terrain dominate this early 1980s survey of southern Arizona. The landscape is defined by a complex network of canyons including Fresno Canyon, Cumero Canyon, and Providencia Canyon, which channel toward the Santa Cruz River in the south. The map documents a transition from the agricultural and ranching history of the Circle Z Ranch and T 4 Ranch to the industrial legacy of the Patagonia Mountains.

Mineral exploration is evident throughout the eastern slopes, where numerous claims such as the Three R Mine, European Mine, and Flux Mine are recorded. This era also highlights regional infrastructure with the Nogales International Airport and its Airway Beacon positioned north of Kino Springs. Local community roots are anchored by the Santa Cruz School and the historical land grant boundary of Baca Float No. 3, offering a detailed view of property and land use before late-century development intensified.
