There are a number of water filled sink holes, called blue holes, around the world. They are usually around 300 feet in depth. The deepest, at a depth of 663 feet, is Dean’s Blue Hole in a bay of Long Island, Bahamas. The hole is a near circle at the surface with a diameter of over 100 feet at some points. The hole widens to a diameter of over 300 feet around at a depth of just over 60 feet. The deep column of water is a deep blue when looking down the hole itself. There is more to see in the area than just a beautiful hole in the ocean floor.
The depth of Dean’s Blue Hole makes it a popular location for free divers. A platform can sometimes be seen over the hole to provide a stable base for the diver or divers. The platform may also be home to cameras and crew if the dive is being documented for television or an informative documentary. Naturally formed shelves inside the hole make for leisurely resting places for the divers to sit and enjoy their submerged view.
Nearby is Turtle Cove. It features a variety of colorful coral and various types of sea life. Many native species like parrot fish, butterfly fish, and blue damsels can be seen swimming amongst the reefs. There have also been sightings of non-native lionfish. Larger denizens of the oceans, such as dolphins and sharks, have been known to enjoy the waters of Long Island. Sea turtles make appearances as well.
The natural forces that formed Dean’s Blue Hole didn’t stop there. They have also created other, smaller blue holes around the island. Other natural features include tall stone arches and underwater pinnacles. These features also include inland caves that are home to different species of bats.
