2018 Map of Tinajas Altas OE S

About this map

The international boundary between the United States and Mexico defines the northern edge of this arid landscape, where the USA E U Mexicanos border line cuts across the desert terrain. This map captures a strictly natural environment dominated by a complex network of dry washes and desert drainages. These hydrologic features create a delicate pattern across the sheet, illustrating how water moves through the basin during rare precipitation events. In this specific region, the absence of human settlements, roads, or structures highlights the environmental isolation at the southern reaches of the Yuma County desert, preserving the character of the land exactly as it was surveyed in the late 2010s.
