Abstract: Salt works of the Salton Basin
Purpose: These data are intended for geographic display and analysis.
Supplemental_Information:
Long before there was a Salton Sea, there was salt in the basin. The floor of the basin, which is an extension of the Gulf of California, is almost 275 feet below sea level. The salt deposits, first discovered in 1853, alternated between a salt marsh and a bed of dry salt as weather conditions and inflow from the Colorado changed. Although the salt deposits were well known and utilized by local Native Americans, it wasn't until 1884 that commercial production began. The New Liverpool Salt Company began operations on the north end of the basin scraping the salt crust with plows. The rock salt deposit covered 1,000 acres and produced 2,000 tons of salt a year. The operation consisted of plows guided by local Cahuilla Indians that cut a wide shallow furrow in the crust. The salt piled in ridges on either side of the furrow and was raked into piles and transported to mills. Each plow could harvest 700 tons of salt a day. At the mill, the salt was reduced in size by breakers where it was then ground, cleaned, graded, and sacked. The salt was used by factories, dairies, druggists, and for table use and sold for $6 to $36 per ton depending on grade. In 1905, flooding destroyed the New Liverpool Salt Works. There was no other attempt at salt production in the basin until 1919 when The Mullet Island Paint Company produced a small amount of salt from hot springs. In 1934 the Mullet Island Development Company obtained salt from salty wells in the basin. The Mullet Island Salt Works of the Reeder Salt Company operated three evaporation ponds from 1940 to 1942 on land leased from the Imperial Irrigation District, which supplied salt for local icing and refrigeration cars. From 1927 to 1930 Seth Hartley operated four concentration ponds near Mecca and experimented with solar evaporation ponds near Caleb. In 1935 Seth and Chester Hartley opened The Imperial Salt Company, the biggest of the salt operations, on land leased from the Imperial Irrigation District near Frink. It was bought by the Western Salt Company in 1942. Before closing in 1947 it reported the production of 16,000 tons of salt per year from 175 acres of evaporation ponds.
