Cadiz Lake dominates this desert landscape in the eastern Mojave, where industrial salt extraction intersects with shifting sands. The map details the massive footprint of the lake bed and its surrounding Cadiz Valley, an area characterized by drainage patterns like Watson Wash and Browns Wash. A striking feature of the early 21st-century terrain is the Salt Evaporation Rd, which leads to a series of distinct evaporation ponds carved into the salt crust. To the northeast, the Cadiz Dunes provide a stark contrast to the flat, mineral-rich expanse of the dry lake basin. This survey documents the intersection of natural desert geomorphology and large-scale industrial mineral recovery during a period of ongoing resource development in San Bernardino County.
