About this map

The vast industrial basin of Searles Lake dominates this 1970s landscape, defined by a specialized chemical and mineral extraction infrastructure. The map details an extensive network of Salt Wells, a complex Aqueduct system, and large processing areas including the Salt Evaporator and smaller Salt Evaporators. These features illustrate the intensive salt and soda harvesting operations within the Searles Valley (Depression), where water management and industrial waste, such as the Industrial Waste Pond, are central to the terrain's utility.

Technological history is visible through the Dismantled Monorail and an Old Railroad Grade that traverse the eastern dry lake bed. To the southeast, the boundary of the Naval Weapons Center meets the edge of China Lake, marking a transition from industrial salt production to military use. Other local landmarks like the Landing Field and various Ruins suggest a history of remote desert habitation and logistical support for these desert industries.
