1965 Map of Picacho SW

USGS Topo · Published 1973

About this map

The Colorado River snakes along the boundary between Imperial Co and Yuma Co, defining the arid borderlands between California and Arizona in the mid-1960s. This survey illustrates the river's dynamic hydrological environment, where the main channel is flanked by a complex network of backwaters like Adobe Lake, Nortons Lake, and Taylor Lake. The transition between the Picacho State Recreation Area and the Imperial National Wildlife Refuge marks a landscape of preservation and rugged isolation.
