Divers have found the "holy grail" of shipwrecks. It was a 1780 British warship, called the HMS Ontario. It's being claimed that it's "the oldest confirmed shipwreck and the only fully-intact British warship to have ever been found in the North American Great Lakes." It's nearly intact. There are even two windows that aren't broken.
