1957 Map of Twin Buttes

About this map

The San Xavier Del Bac Mission lands and the rugged peaks of the Sierra Sierrita anchor this mid-century portrait of southern Arizona. The landscape is defined by a ranching and mining economy, where vast holdings like Canoa Ranch, Ruby-Star Ranch, and McGee Ranch are interspersed among significant copper operations. The industrial footprint of the Pima Mine and Banner Mine is clearly visible, including the Pima Mine Tailings Pond near Mineral Hill. The eastern portion of the map follows the corridor of the Santa Cruz River and the Southern Pacific railroad, illustrating the primary transportation arteries through the San Ignacio de la Canoa land grant. Numerous washes, such as Demetrie Wash and Esperanza Wash, carve through the terrain toward the river valley, marking the natural drainage patterns of this arid region.
