Great Blue Hole
From Wikipedia, the free encyclopedia
The Great Blue Hole is a large underwater sinkhole off of the coast of Belize. It lies at near center of Lighthouse Reef, a small atoll 60 miles from the mainland and Belize City. The hole is almost perfectly circular, over 1,000 feet across and 400 feet deep. It was 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.
[edit] Discovery
This site was made famous by Jacques-Yves Cousteau who declared it one of the top ten scuba diving sites in the world. In 1971 he brought his ship, the Calypso to the hole to chart its depths.
