Dean's Blue Hole

Canadian free-diving champion William Winram descends into Dean’s Blue Hole during the 2009 Vertical Blue competition. Winram is competing in the free immersion event, in which a diver pulls himself down and back up to the surface using a guide line. He set a Canadian and Pan-American record of 90 meters (296 feet) during the dive.
