Lost California Treasure

Butler's Buried Cache

During the Gold Rush, a prospector named Butler operated an incredibly rich placer claim on a bend of the Mokelumne River that yielded up to fifty thousand dollars daily. Distrustful of banks and under pressure from litigation over legacy shares of the claim, Butler buried his daily gold surpluses near the riverbed. After his sudden death from fever, administrators found his bank deposits, but his associates confirmed his substantial daily surplus gold remained hidden near the claim. In 1963, the construction of Camanche Dam inundated the entire town of Lancha Plana and Butler's claim under deep water and silt.
