2018 Map of Red Hill SW

About this map

The Chocolate Mountains dominate the northern landscape of this California desert region, where seasonal drainage patterns define the local geography. Significant desert conduits such as McAllister Wash, Indian Wash, and Los Angeles Wash intersect the arid terrain, illustrating how water historically moved across the basin toward the south. The southern edge of the quadrangle marks the border between La Paz and Yuma counties, a transition signaled by the shift from the Colorado Desert into the Lower Colorado River Valley ecosystem.
