History - Deep Sea Detectives Secret Underwater Caves

Within the Island of Cozumel in Mexico, there winds a 6-mile underwater cave system named Cueva Quebrada. Almost a mile from any entrance lies a significant cache of Mayan artifacts, a burial mound, found in 1991 by cave explorers Jeff Bozanic and Steve Ormeroid. How did the Mayans place these objects a mile back into the cave system? Deep Sea Detective John Chatterton trains to become a cave diver and use the newest technology for a deep and treacherous dive to solve the mystery.
