1956 Map of Plaster City NW

About this map

The Fish Creek Mountains dominate the western horizon of this 1950s Imperial County landscape, where the steep desert topography meets the vast expanse of the West Mesa. This transition from high peaks to alluvial plains is defined by the broad Carrizo Wash, which drains the canyon systems toward the southeast. The map reveals a region heavily utilized for military and industrial purposes during the mid-century, most notably by the Carrizo Naval Impact Area Reservation and a separate Naval Reservation further south.
