In the Caribbean Sea, 60 miles off the coast of Florida, there is a paradise known as the Bahamas. This is a place full of attractions; they draw millions of tourists each year. But these visitors aren’t here for sun or sand, though they may be in for a bit of a gamble. They’ve come to search for a lost world. They’re extreme explorers, astronauts of an inner space called blue holes.
Blue holes get their name from the dark blue of their depths. And, while they don’t look like much at the surface, what seems like a small pond can go thousands of feet down and spread out into a maze of underwater passages and tunnels. The mystery of their depths beckons the able and the foolhardy alike. On average, 20 divers die each year in caves like this.
But to these explorers, it’s worth the risk, because blue holes aren’t just spectacular, some preserve the past like a liquid time capsule. Diving them will take the explorers back thousands of years, where there are hints of an ancient, lost Bahamas.
What did this world look like then and who lived here? Now, an unprecedented expedition pairs expert cave divers with world-class scientists to find out.
