Rancho de la Osa and the international border crossing at Sasabe define this desert landscape in the late 1990s. The map illustrates a transborder community where settlements like Chihuahua and El Sasabe sit just south of the line, while the Buenos Aires National Wildlife Refuge occupies the northern flats. The terrain is dominated by the Sierra Pozo Verde, with the Pozo Verde Mts providing a sharp contrast to the drainage of the Arroyo del Sasabe. Grounded in ranching and border commerce, the map identifies specific local sites including the U.S. Customs post, a rural Cemetery, and several smaller outposts like Aduana and Garcia Ranch. The presence of an Aqueduct and scattered water features like La Osa Tank underscore the critical role of water management in this arid environment.
