2021 Map of Red Hill SW

About this map

The Chocolate Mountains dominate the northwestern corner of this landscape, which is defined by a series of broad, braided drainage systems moving southwest through the desert. These extensive alluvial networks, including McAllister Wash and Indian Wash, reveal the natural hydrology of the lower Colorado River region before it meets the La Paz and Yuma county line. The presence of routes like Red Cloud Rd and the Painted Desert Trl suggests a history of localized desert travel and access to the interior of the mountains, while Los Angeles Wash cuts through the southeastern quadrant. This 2021 update maintains the Public Land Survey System grids, such as t4s r21w, which frame the sparsely populated but geographically complex terrain.
