The international border between the United States of America and Estados Unidos Mexicanos cuts diagonally across this desert landscape, marking the southern edge of the Yuma County wilderness. The topography is dominated by the jagged elevations of the Cabeza Prieta Mountains and the Tule Mountains, which rise sharply from the arid floor. In an environment defined by extreme aridity, essential water sources are clearly identified, including Buckhorn Tank and Tule Tank. These features represent critical survival points for travelers and local fauna in the borderlands. The map provides a precise layout of the Public Land Survey System grid, including townships t13s r15w and t14s r15w, illustrating how geopolitical boundaries were imposed over this ancient, stark terrain.
