1976 Map of Calipatria
USGS Topo · Published 1976About this map
The Salton Sea dominates the northwestern portion of this 1976 survey, its shoreline defined by the Salton Sea National Wildlife Refuge and the Imperial State Wildlife Area. This landscape in the Imperial Valley is a complex grid of intensive irrigation, where the Alamo River and New River flow toward the sea amidst a dense network of canals like the Westside Main Canal and Trifolium Canal. The map captures the agricultural and industrial character of the region, featuring Carbon Dioxide Wells, geothermal indicators like the Mud Pots, and extraction sites at Obsidian Butte and Rock Hill. Settlements such as Calipatria, Westmorland, and Niland serve as hubs along the Southern Pacific rail line, illustrating the mid-century dependence on both rail transport and managed water for desert reclamation.
