  • Description:

    The Mary Ann was the first vessel to be registered in the "Dominion of Canada" on July 1 1867. Thought to have been resting in the Graveyard of Ships off the coast of Thunder Bay, the Mary Ann was discovered by two members of SOS Superior Chapter when they were going to dive a different wreck. A happy error of a hundred meters or less led to the descent onto the previously unknown Mary Ann. More overall details will be uploaded as to size, depth, etc
