The United States-Mexico border defines the southern reach of this Pima County landscape, where the high ridges of the Baboquivari Mountains meet the desert floor. In this arid environment, human activity and survival are tied to the collection of water, evidenced by a network of named sites such as Coyote Tank, Saguaro Tank, and Antonio Tank scattered across the district. Small settlements like Kom Kug, Sapano Vaya, and Newfield are positioned along the lower elevations, while Buenos Aires sits near the international line.
