1965 Map of Little Picacho Peak

USGS Topo · Published 1966

About this map

Little Picacho Peak stands as the primary landmark in this desert landscape, overlooking an intricate network of drainage channels that define the arid terrain of Imperial County. The eastern edge of the map follows the Colorado River corridor, where the Imperial National Wildlife Refuge encompasses the waters of Ferguson Lake. This 1965 survey reveals a terrain shaped by both natural erosion and human extraction, with numerous prospects and the Hess Mine located near the headwaters of various washes. The network of seasonal watercourses, including Senator Wash, Marcus Wash, and Mission Wash, dictates the movement across the land, often paralleled by unnamed jeep trails used by mineral explorers. The presence of Gravel Pits in the southeast corner near the river reflects the ongoing infrastructure and industrial activity necessary for managing the border region's resources during the mid-1960s.
