Olancha was established by Minnard Farley, who came to the area in 1860 and discovered silver ore in the nearby Coso Range.

The remains of a stone wall from this mill still exists and has been designated as a California Historical Site.The first post office at Olancha opened in 1870.
On August 11, 1969, Manson Family members Charles "Tex" Watson and Dianne "Snake" Lake settled down in Olancha two days after Watson had stabbed Sharon Tate to death. Here, Watson bought a newspaper revealing that it still was a mystery who committed the Manson murders and confessed to Lake: "I killed her, Charlie ordered me to do so, it was fun". This fact was witnessed by Lake during the Watson trial in 1971. Lake was shortly put into custody in Independence after complaints from Olancha residents for swimming nude. After a few weeks, the two of them left Olancha for the final Manson hideout in Death Valley.
