2011 Map of Red Hill SW

About this map

Yuma Proving Ground occupies the southern portion of this desert landscape, where the administrative boundaries of the military installation intersect with a network of desert washes and unpaved access roads. The hydrology is dominated by ephemeral systems including McAllister Wash and Indian Wash, which drain the arid terrain from the northwest to the southeast. Transportation through this remote section of Imperial County relies on a series of rudimentary routes, most notably Palo Verde Point Rd, Red Cloud Rd, and Indian Wash Rd. These roads provide the primary points of reference for navigating the alluvial fans and drainage patterns that characterize the area's geography during the early twenty-first century.
