1956 Map of Iris Wash

USGS Topo · Published 1957

About this map

The Chocolate Mountain Aerial Gunnery Range dominates this mid-century landscape in Imperial County, reflecting the transition of the California desert into a critical military training ground. This 1956 survey captures the Camp Dunlap Naval Reservation and the specific Camp Dunlap (Site), an area that would later become known as Slab City. The infrastructure of desert agriculture and water management is clearly marked along the western edge, where the Coachella Canal and East High Line Canal parallel the foot of the East Mesa.
