The international boundary between the United States of America Estados Unidos Mexicanos cuts diagonally across this desert landscape southeast of Yuma. This 2018 survey illustrates a starkly linear frontier defined by the presence of Border Rd, which runs parallel to the national divide. The terrain is characterized by subtle topographic contours and the grid-based sections of the Public Land Survey System, including portions of t11s r23w and t11s r22w. Connectivity in this borderland is limited to a few arterial routes like Ave 3e, reflecting the specialized nature of the region's geography. The map provides a clear look at the intersection of international policy and physical landscape in the far southwestern corner of Arizona.
