1990 Map of Engesser Pass

USGS Topo · Published 1990

About this map

The Kofa Mountains dominate this 1990 survey, representing a landscape where mineral extraction and wildlife conservation intersect. The map documents the Engesser Mine, alongside various Adit and Mine Shafts markings, indicating a history of prospecting in the high desert. Much of the territory falls within the Kofa National Wildlife Refuge, where the preservation of native habitat is contrasted by the eastern border of the Yuma Proving Ground. Notable landmarks like Courthouse Mountain and Black Dome provide vertical relief above the broad Palomas Plain and King Valley. Vital water sources in this arid environment are scarce, with Frenchman Tank serving as a primary named catch basin for the region. This provisional edition was updated from aerial photography taken in 1985 and field-checked in 1987, capturing the remote infrastructure of Yuma County.
