A Navy tug, missing since 1921, has been found near the Farallones Islands, about thirty miles west of San Francisco, California.
The USS Conestoga disappeared after leaving San Francisco on 25 March 1921, en route to American Samoa. The disappearance sparked an air and sea search, but the tug and its crew were declared lost in June of that year. Investigators believe the Conestoga sank as it tried to reach a protected cove to escape heavy winds and rough seas.

Rico says it's not the only wreck on the Farallones...
