Amazing Facts About What’s At The Bottom Of The Great Blue Hole In Belize

The Great Blue Hole is the world’s largest sinkhole located off of the coast of Belize. It was made famous in 1971 by undersea explorer Jacques Cousteau when he first visited it to chart its depths. Cousteau declared it one of the top five scuba diving spots in the world and came to the conclusion that the phenomenon was created thousands of years ago when rising ocean levels led to the series of caves to become flooded. Recently, a team of scientists, including billionaire Richard Branson made an expedition to the bottom. Check out their findings and other fascinating facts about the Great Blue Hole.

In December 2018, a team was assembled to embark on a journey to the bottom of the Blue Hole to see if they could make any further discoveries. Among the team was billionaire Richard Branson and Fabien Cousteau, the grandson of Jacques Cousteau, the man who put the hole on the map in the early 1970s.

Using two submarines, they were able to collect footage of their descent and even created the first-ever 3D map of the cavern’s interior. Chief Pilot Erika Bergman explained "We did our complete 360 sonar map and that map is now almost complete. It looks really cool, it’s this mesh-layered, sonar scan of the entire thousand-foot diameter hole."
