2021 Map of Tinajas Altas OE S

About this map

The international border between the Usa Mx dominates the northern edge of this arid landscape in Yuma County. This remote desert terrain is defined by a complex network of ephemeral washes and drainage patterns that stretch across the quadrangle, illustrating the natural hydrological flow of the southwestern desert. The map, produced from 2019 imagery and recent topographic data, serves as a contemporary record of this unpopulated region along the boundary line. While modern in its data collection, the sheet reveals a landscape that remains largely unchanged by infrastructure, preserving the raw physical geography of the Arizona-Mexico borderlands.
