1986 Map of Tweed Mine

About this map

The Chocolate Mountains dominate this 1980s landscape, a region defined by its intersection of military operations and historical extraction. Most of the territory falls within the Yuma Proving Ground, where the Military Reservation Boundary delineates a vast expanse of desert terrain used for testing. For those tracing the history of desert mining, the map provides precise locations for the Tweed Mine, an isolated Mine Shaft, and numerous unnamed Prospect and Prospects sites. The drainage patterns of the Tyson Wash, Mohave Wash, and Gould Wash reveal the erosional forces shaping this arid corner of La Paz and Yuma counties. This provisional edition preserves the industrial and tactical geography of the area just as modern mapping technologies were beginning to refine these remote desert coordinates.
