Great Blue Hole, Belize
This IKONOS image, acquired on 08 December 2012, shows the Great Blue Hole, a near perfect circle off the coast of the Belize mainland. It is a submarine sinkhole surrounded by the shallow waters of the Lighthouse Reef Atoll, a small atoll 43 miles from the mainland.
The hole is over 984 feet across and 407 feet deep. The Great Blue Hole, which became a World Heritage Site in 1997, 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).
