Potash wars (California)
The Potash wars were a series of conflicts over mineral rights that took place from 1910 to 1915 in the Searles Valley near Searles Lake, a dry lake (also called Slate Range Lake and Borax Lake), near the present-day town of Trona in San Bernardino County, California. The Potash wars gained national and international attention at the time due to the involvement of famous lawman Wyatt Earp and the importance of the valley's supply of potash, a term referring to various potassium salts widely used as crop fertilizers for which the Searles Valley was a major supplier in the 1910s.
