Dean's Blue Hole
Dean's Blue Hole - is the deepest now known blue hole in the world. The hole is located in the bay west of the town of Clarence Town Long Island Island, Bahamas. Its depth is 202 m
Most blue holes and failures account for a maximum depth of 110 meters, but Dean's Blue Hole deepens more than 200 meters, which makes it exceptional. On the surface it looks almost circular with a diameter of 25 to 35 meters. After a descent of 20 meters mouth of the cave significantly expands up to 100 meters in diameter.
The so-called blue holes in stark contrast dark blue deep water with a light blue shallow water around them. They were formed during the last ice age, when sea level was 100-120 meters lower than at present. These holes are formed deep groundwater, which gradually dissolved the limestone, while the ceiling of these voids are not attacked. Later, the sea level rose and filled them with water.
Dean's Blue Hole has become a popular destination for scuba diving and snorkeling. In 2012 at the World Championships in freediving participant from New Zealand William Trabridzh set a world record by diving without equipment to a depth 121 meters in the deepest blue hole.
