About this map

The international boundary between United States Mexico and Arizona Sonora defines this 1979 survey of the southern Pima County borderlands. The small settlement of Sasabe serves as the focal point, characterized by its U S Customs station and its position as a gateway between nations. The landscape is a desert expanse of washes and arroyos, including the Arroyo del Sasabe, which drains the terrain near the foothills of the Pozo Verde Mtns.

Evidence of established ranching life is visible through family-named landmarks like Garcia Ranch and the historic Rancho de la Osa. The map details the vital water infrastructure necessary for survival in this arid environment, specifically naming La Osa Tank and various scattered wells. Route 286 provides the primary transit artery, connecting these isolated ranching outposts and the border community to the north.
