The Great Blue Hole (Belize)

The Great Blue Hole in Belize is a massive, circular underwater sinkhole, about 1,000 feet wide and 410 feet deep. Located off the coast of Ambergris Caye, it was formed thousands of years ago during periods of rising sea levels, when limestone caves collapsed. Today, it's a popular site for divers who marvel at its clear blue water, stalactites, and interesting marine life. The Blue Hole's striking shape and depth make it a natural wonder and an important location for scientific study of geological and climatic history.
