but before, let me tell you 1st bout special hole *the hole which is so special for me haha….. Blue holes formed during past ice ages, when sea level was as much as 100–120 metres (330–390 ft) lower than at present. And when the ice ages was end then ice was melted and that’s when the sea level rises and the cave covered with sea water up to the Blue Hole was formed.
and here is The deepest blue hole in the world—at 202 metres (663 ft)—is Dean’s Blue Hole, located in a bay west of Clarence Town on Long Island, Bahamas.
