THIS SHIT FREAKS ME OUT-The Great Blue Hole, a mysterious, amazing and wonderful bit of nature thousands of years old. They are underwater sinkholes also called Vertical Caves. There are many different blue holes located around the world, but the best known is 'The Great Blue Hole" of BELIZE.
The Great Blue Hole by the livingmoon. Photo by David Doubilet: Located off the coast of Belize, the almost perfectly circular Great Blue Hole is a sinkhole which measures more than 300m across and 120m deep and is believed to have been formed as a limestone cave system during the last ice age when sea levels were much lower. As the ocean began to rise again the caves flooded, and the roof collapsed. #Great_Blue_Hole #Sinkhole
