By Unknown author -, Public Domain,



"ARGONAUT AND KENNEDY MINES - Argonaut Mine, discovered 1850, and Kennedy Mine, discovered 1856, played dramatic roles in the economic development of California, producing $105,268,760 in gold. Kennedy Mine has a vertical shaft of 5,912 feet, the deepest in the United States. The Argonaut was the scene of the Mother Lode's most tragic mine disaster-on August 27, 1922, 48 miners were trapped in a fire at the 3,500-foot level - few survived. Both mines closed in 1942." - California Historic Landmark No.786
