The Great Blue Hole, found near the center of Lighthouse Reef off the coast of Belize, is one of nature"s most incredible creations. The massive marine sinkhole, 1,043 feet across and 407 feet deep, was formed during the last ice age when a limestone cave system collapsed and rising sea levels flooded the area, leaving behind a striking natural wonder.
