About this map

The Yuma Proving Ground dominates the western half of this arid landscape, its boundary cutting through the eastern foothills of the Chocolate Mountains. This 1986 provisional survey documents a region defined by military and conservation land use, where the expansive Castle Dome Plain meets the rugged terrain of the Kofa National Wildlife Refuge. The drainage of Indian Wash snakes through the valley floor, revealing a desert environment modified by selective human activity. Evidence of mineral exploration appears in isolated Prospects and a specific Mine Shaft, while more modern infrastructure is noted via a Radio Tower and a Gravel Pit. A Check Dam along the wash highlights water management efforts in this dry corridor on the border of La Paz and Yuma counties.
