The Quedah Merchant, a ship captured by the pirate (or was it privateer?) Captain Kidd has been found untouched in ten feet of water off Catalina Island in the Dominican Republic. "When I first looked down and saw it, I couldn't believe everybody missed it for 300 years," said Charles Beeker, a scuba-diving archaeologist who teaches at Indiana University. "I've been on thousands of wrecks and this is one of the first where it's been untouched by looters." The site will be turned into a national park. Captain Kidd sailed the entire length of the East Coast of the United States. It is rumoured that he buried treasure on several beaches between the Carolinas & Cape Cod.

Here's the story of the wreck.
