USGS Topo · Published 2003

About this map

Chocolate Mountain Aerial Gunnery Range dominates this landscape in Imperial County, reflecting a mid-20th century transition from traditional mining to military training. The map shows the Camp Dunlap (Site) near the Coachella Canal, a location that evolved from a World War II Marine Corps base into a seasonal settlement area. Infrastructure like the East Highline Canal and Siphon points to the vital irrigation engineering required to manage water in this arid environment.
