1986 Map of Red Hill SW
USGS Topo · Published 1986About this map
The Chocolate Mountains dominate the western landscape of this mid-1980s topographic record, where the arid terrain meets the vital waters of the Colorado River. The map documents a significant intersection of military and conservation land use, with the vast Yuma Proving Ground covering much of the central and eastern portions. Along the river corridor, the Imperial National Wildlife Refuge protects the riparian ecosystem, including Mc Allister Lake and shoreline features like Mesquite Point and Palo Verde Point.
