Hangout in an Ancient Maya Cave
Relive the adventure from our live Google+ Hangout on Air with underwater archaeologist Guillermo de Anda, from a sacred Maya cave. More than 1,000 years ago, ancient Maya visited this cave for the sacred waters inside, building a large stone pyramid and carving a ladder that Guillermo and his team use to this day. Also joining were paleontologist Jørn Hurum and geo-archaeologist Beverly Goodman, as well as public participants in Texas and Manchester, England.
