After a lifetime of service with the Royal Canadian Navy, the 112 meter HMCS Columbia was sunk as an artificial reef in 1996 on the inside of Maud Island. Sitting out of the main currents, the Columbia is an excellent dive when the currents are running through the nearby Seymour Narrows. Although much of the wreck sits below 20 meters deep, the marine life is still finding the hull a comfortable home. Poking your head into stairwells on the top deck will come face to face with a large Cabezon or Ling Cod that has taken up residence. The hull is often covered with Swimming Scallops and Grey Brittle Stars. If you stare down the barrel of one of the deck cannons, you will find a Quillback Rockfish hiding from predators. Check out the deck vents that go to the engine room for Giant Pacific Octopus.
