About this map

The international border between the United States and Mexico cuts diagonally across this 2014 survey, marking a stark division in the arid landscape. The northern portion of the quadrangle is dominated by volcanic features and desert basins, including the edge of the Pinacate Lava Flow and the wide Pinacate Valley. These geological formations provide a clear view of the transition from the high relief of Monument Bluff into the expansive sands of the Tule Desert.

This survey serves as a modern record of the borderlands where Arizona meets Sonora. The landscape is defined by its topographic extremes, from the scorched remnants of ancient lava fields to the alluvial fans and drainage patterns that characterize this reach of the Sonoran desert. Researchers can trace the path of the international boundary as it passes through sections of t15s r12w and t15s r13w.
