1948 Map of Twin Buttes

About this map

The Santa Cruz River corridor south of Tucson is defined here by a network of large ranch holdings and mining activity during the late 1930s. Landmarks like Canoa Ranch and the San Ignacio de la Canoa land grant boundaries anchor the southern portion of the sheet, while the northern area is dominated by the San Xavier site and the sharp rise of Mineral Hill. The map documents a landscape of scattered family-named outposts such as McGee Ranch, which supported its own McGee Sch, and Esperanza Ranch, illustrating the remote settlement patterns of Pima County before post-war expansion.
