About this map

Sonoita serves as the primary cross-border anchor in this late 20th-century survey of the Sonoran frontier. The international boundary bisects the arid landscape, separating the southern edge of Organ Pipe Cactus National Monument in Arizona from the complex network of Mexican settlements and ranchos. To the north, the Sonoyta Valley and isolated landmarks like Gachado Well indicate the reliance on water sources in this desert environment. South of the border, the terrain shifts dramatically into the high peaks of the Sierra Cubabi. The map details a transition from American conservation land to a populated Mexican agricultural and residential landscape, including smaller communities such as Hombres Blancos, Adolfo Lopez Mateos, and Emancipación Obregonista, many of which are linked by unimproved roads and trails across the rugged desert floor.
