1954 Map of Little Picacho Peak

USGS Topo · Published 1955

About this map

The Chocolate Mountains dominate this arid landscape along the California-Arizona border, a region defined by sharp ridgelines and deep drainage channels in the mid-1950s. The eastern edge of the survey captures the vital interface between the desert and the Colorado River, where the Imperial Reservoir and Ferguson Lake provide a stark contrast to the surrounding parched terrain. This area is managed as part of the Imperial National Wildlife Refuge, preserving a critical riparian corridor.
