About this map

Little Picacho Peak stands as the dominant landmark in this arid stretch of Imperial County, California, where the landscape is defined by an intricate network of desert drainages. The eastern edge of the quadrangle is bordered by the Imperial National Wildlife Refuge, marking the transition toward the Colorado River corridor. The interior is largely accessible only by a system of Jeep Trails that wind through the topography, connecting remote mining interests and geological features.

Evidence of small-scale mineral exploration and resource extraction is scattered throughout the region, most notably at the Hess Mine and various Prospects located near Copper Basin. Large desert washes, including Marcus Wash, Ferguson Wash, and Senator Wash, cut through the elevation, illustrating the natural drainage patterns that have shaped this environment. These features provide essential context for researchers and geologists interested in the mid-20th-century desert landscape and its sparse but persistent industrial footprint.
