1905 Map of Nogales

About this map

The United States Mexico border defines the central axis of this military survey, tracing the international boundary between Arizona and Sonora. This advance sheet, compiled from field work by T.M. Bannon and others, details the early 20th-century ranching and mining infrastructure of the Santa Cruz region. The landscape is dominated by family-held lands such as Mariposa Ranch, Buenavista Ranch, and Estrada's Ranch, while industrial activity is evident at The Mowry Mine and the El Pilar Mine Co. south of the line. The Southern Pacific R. R. of Mexico provides the primary transport corridor, winding past Mascareñas Sta. and Sta. Agua Zarca as it follows the drainage of the Santa Cruz River. Numerous canyons and peaks, including Mt. Benedict and Cuchilla Pelona de Molera, define the rugged watershed of the Sonoran Desert borderlands.
