Cadiz Valley and its distinctive dry-lake topography dominate this portion of the Mojave Desert in San Bernardino County. The landscape is defined by the stark industrial infrastructure of brine harvesting, most notably the network of the Salt Evaporator Plan Rd which services the large evaporation ponds used for mineral extraction. To the southwest, the terrain rises toward Calumet Mountain, marking the transition from the flat basin floor to more elevated ground. Ephemeral drainage patterns are traced by Watson Wash in the northwest and Browns Wash in the northeast, illustrating how water occasionally moves through this arid environment. This survey captures a specialized industrial landscape where natural geology and salt production intersect in a remote corner of California.
