1939 Map of Twin Buttes

About this map

The Sierrita Mountains dominate this landscape south of Tucson, showing a region defined by cattle ranching and early mining at the end of the 1930s. Settled outposts like Pino Blanco Ranch and Batamote Ranch are scattered throughout the desert foothills, while the Santa Cruz River valley provides a corridor for transport and larger holdings like Canoa Ranch. The Southern Pacific railroad parallels the river through Canoa, marking the primary artery for the local economy. In the northern reaches, the San Xavier mission and nearby Mineral Hill reveal the complex history of religious and extractive development. This survey documents a transitional era where traditional ranching life, centered around features like McGee Sch, coexisted with industrial interests at the Twin Buttes settlement.
