The Great Blue Hole

The Great Blue Hole is a mystery to all of us. It was formed during quaternary glaciation while sea levels were much lower, the formation started over 153 000 years ago. For the people who do not know what the blue hole is, it is a massive sink hole in the middle of the ocean and it is located in the Atlantic ocean and the Carribean sea. It was made number 1 on the list of "the ten most amazing places on earth" in 2012. It became famous when it was declared as one of the top 10 scuba diving places in 1970. It is quite a popular tourist attraction for scuba divers to experience but there are only two places allowed to dive in the North and South areas of the hole. Yet, you can snorkel just around the perimeter of the hole. The hole is 1000 feet across and 460 feet deep. It is also located off the coast of Belize. A british diver came up with the actual name of  "The Blue Hole"which used to be known as "The Great Berrier Reef".
