Blue Hole, Lighthouse Reef, Belize

Approximately 60 miles (100 kilometers) from Belize City, the almost perfectly circular Blue Hole is more than 1,000 feet (305 meters) across and some 400 feet (123 meters) deep.

The hole is the opening to what was a dry cave system during the Ice Age. When the ice melted and the sea level rose, the caves were flooded, creating what is now a magnet for intrepid divers.

Impressive as this blue hole is, its not the deepest. The deepest (known) can be found to the north of Long island, at turtle bay in the Bahamas. The Dean's Hole is 663 foot deep but sadly the GE resolution of this area is low res :(
