The international boundary between United States of America Estados Unidos Mexicanos and Arizona Sonora cuts diagonally across this 1996 survey, defining a landscape shaped by conservation and military use. Much of the northern terrain is occupied by the Cabeza Prieta National Wildlife Refuge and the Cabeza Prieta Wilderness, areas preserved for their distinct desert ecosystems. To the north, the boundary of the Barry M. Goldwater Air Force Range indicates the region's role in national defense. The intermittent watercourse of Sonoita meanders through the southern portion of the quadrangle, highlighting the scarce but vital riparian patterns in this arid borderland. This map captures the intersection of sovereign borders and expansive federal land management in Pima County.
