Borax was discovered on the nearby surface of Searles Lake by John Searles in 1862. With his brother, Dennis, he formed the San Bernardino Borax Mining Company in 1873 and operated it until 1897. The chemicals in Searles Lake, which include borax, potash, soda ash, salt cake, and lithium, were deposited here by the runoff waters from melting ice age glaciers. John Searles' discovery has proved to be the world's richest chemical storehouse, containing half the natural elements known to man.

Many of these plaques have since been recast or their texts revised. The California Historical Landmarks program and its current texts are maintained by the California Office of Historic Preservation. California Office of Historic Preservation ↗
