The "Dean's Blue Hole" are deepest hole in the world and specifically in the western Gulf of Clarence Town on Long Island,


 It was discovered researchers that the reason behind the genesis dates back to the groundwater, which was conducted under the ice, which led to a period of time to corrosion layers of limestone, which was taking place above it, and after that the sea level rose filled with this hole with water to become one of the deepest drilling in the world.
Scientists say that it has also formed in the ice age, when sea level was less than 100 to 120 meters from this time.























This crater has been named this name to contrast dark blue in color depths, and the light blue color on the surface.
