Almost a century ago, the USS Conestoga sailed from San Francisco Bay and vanished with 56 men on board. Last year, we and the U.S. Navy announced that we had discovered the wreck and solved the mystery: the shipwreck now rests within the waters of Greater Farallones National Marine Sanctuary. Hear Conestoga's amazing story in our video, and find out more at sanctuaries.noaa.gov/conestoga.
