1954 Map of Salton Sea

USGS Topo · Published 1954

About this map

The Salton Sea dominates the southwestern corner of this mid-century landscape, surrounded by an intensive network of irrigation canals and agricultural settlements. The northern reaches of the Imperial Valley are clearly defined by the New River and Alamo River, where towns like Niland, Calipatria, and Westmoreland serve as hubs for the surrounding farm country. East of the sea, the terrain transitions into a series of arid ranges, including the Chocolate Mountains and Chuckwalla Mountains, which are punctuated by isolated mining operations such as the Eagle Mountain Mine and Paymaster Mine. Along the eastern border, the Colorado River serves as the state boundary with Arizona, sustaining the Colorado River Indian Reservation and the riverfront community of Blythe. This survey captures the region's mid-century reliance on managed water systems and mineral extraction, showing the early boundaries of Joshua Tree National Monument before its later expansion.
