About this map

The North Trigo Peaks and South Trigo Peaks dominate this arid landscape in La Paz County, where the desert floor is carved by an extensive network of ephemeral drainage systems. These desert washes, including the prominent Weaver Wash and Petes Wash, illustrate the complex natural irrigation and erosion patterns typical of the Lower Colorado River Valley region. Human presence in this environment is primarily defined by the southeastern corner's intersection with the Yuma Proving Ground, a military installation that necessitates controlled access in this part of the Sonoran Desert.

Water security in this parched terrain is evidenced by specific collection points like Mohave Tanks and White Tanks, which historically served as vital resources for travelers and wildlife. Navigation through the area is largely confined to Cibola Rd, which threads between the drainage basins of Mohave Wash and Mule Wash. This map provides a look at the geographic isolation and military land use that characterizes this borderland territory in the early 21st century.
