Lost California Treasure

Wreck of the SS City of Rio de Janeiro

Known as the 'Titanic of the Golden Gate,' this passenger steamship sank in 1901 after striking a rocky ledge near Fort Point in a dense fog. Rumors immediately spread that the ship was carrying a secret shipment of silver bullion and gold coins destined for China, valued up to $6 million. In 2014, NOAA used sonar and remotely operated vehicles to locate the collapsed hull under 287 feet of water and heavy silt, but no treasure has ever been recovered.
