Koehn Lake and the nearby ghost town of Saltdale have a rich history intertwined with the salt industry in California. Koehn Lake, situated in the Fremont Valley of the Mojave Desert in eastern Kern County, California, is a dry and seasonally endorheic lake, occasionally becoming a closed basin without outflow. The lake is approximately 5 miles long and 3 miles wide at its widest point.
Saltdale, founded in 1915, owes its origins to the salt harvesting operations from Koehn Dry Lake. The town had a post office operating from 1916 to 1950. The history of salt production in the area began in earnest in 1914 with the operations of the Consolidated Salt Company. This was further expanded with the involvement of the Fremont Salt Company from 1919 to 1927, which also utilized solar evaporation of surface brine for salt production.
The salt industry in this region has undergone several changes in ownership and production methods over the years. In the early 20th century, salt production fluctuated considerably, largely dependent on rainfall and storm runoff to supply water for brine formation. Modern techniques involve pumping brine from wells and channeling it to ponds for evaporation, a process that takes about four months to form approximately 6 inches of salt.
Saltdale, during its peak, had a diverse community, including managers, skilled workers, and their families, as well as common laborers, often Latino Catholics. The town had facilities like a company store, a post office, a school, and a service station. Saltdale’s school, under the guidance of notable teachers, played a significant role in community life, including efforts towards “Americanization” by encouraging English language use and cultural integration.
However, Saltdale faced challenges due to its remote location and the fluctuations in the salt industry. The town experienced isolation, difficulties in accessing law enforcement and medical care, and was impacted by the economic conditions of the time, including the Great Depression.
The decline of Saltdale was marked by the eventual abandonment of the town by the 1970s. The salt operations also evolved, with less need for manpower due to modernization. Today, Saltdale stands as a ghost town, with the remnants of its past slowly eroding away in the salty landscape.
Koehn Lake, apart from its salt mining history, has also been used for various other purposes. At its northern end, there are evaporation ponds from the salt mining operation, and the rail siding at the former townsite of Saltdale has been used for offloading explosives. The area around the lake has also been used for testing by the Reaction Research Society and for a desert test track by Honda Motors. In 2014, it was notably the area where Virgin Galactic’s experimental spaceship disintegrated.
The history of Koehn Lake and Saltdale provides a unique glimpse into the industrial and community life of early 20th-century California, highlighting the challenges and adaptations of a community built around a natural resource.
