Ituna, Former Luxury Steam Yacht, Discovered 95 Years after Loss

On March 13, 1920, the 34-year-old Ituna was en route from San Francisco to Reedsport, Oregon when a gale hit and split its seams. While 12 of its 14 crew members escaped, two went down with the vessel when it sank in a matter of minutes. Now, the Office of National Marine Sanctuaries and its partners have used a remotely operated vehicle and an autonomous underwater vehicle to collect high-definition video footage, still images and side scan sonar data of this historic ship.
