Great Blue Hole is a large submarine sinkhole off the coast of Belize
The Great Blue Hole is a large submarine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef a small atoll 70 km (43 mi) from the mainland and Belize City. The hole is circular in shape over 300 m (984 ft) across and 124 m (407 ft) deep. It was formed during several episodes of quaternary glaciation when sea levels were much lower. Analysis of stalactites found in Great Blue Hole shows that formation took place 153000 66000 60000 and 15000 years ago. As the ocean began to rise again the cave was flooded. The Great Blue Hole is a part of the larger Belize Barrier Reef Reserve System a World Heritage Site of the United Nations Educational Scientific and Cultural Organization (UNESCO).
