The Southern Pacific railroad corridor defines the development of this desert landscape, anchored by the small station at Acolita. Surveyed in the early 1950s, the terrain is characterized by the high peaks of the Chocolate Mountains and the Chuckwalla Mountains, separated by the broad drainage of Mammoth Wash. Extensive sections of the map are partitioned by the Naval Reservation Boundary, indicating the mid-century military presence in the Imperial Valley region.
