In Florida’s panhandle, site of Wakulla Springs’ mysterious waters, Wild Chronicles host Boyd Matson puts his life on the line. Boyd dives into this underwater labyrinth of caves, a Swiss cheese of tunnels and flowing springs, where it’s all too easy to get lost.

Join Boyd and the team attempting to generate the world’s first digital, three-dimensional map of an underwater cave system.

  1. Cave diving is sometimes called the "world's most dangerous sport." How many divers have died in Florida's underwater labyrinth?

    • Answer

      More than 300 people have died while cave-diving in Florida.

  2. How much does Boyd's gear weigh?

    • Answer

      Boyd drags 125 pounds of gear to Ginnie Springs, a less dangerous spot for cave-diving than Wakulla Springs.

  3. How do Mark and Jill, the cave divers, collect data for the 3D map?

    • Answer

      Mark and Jill descend with a large piece of equipment that pings the walls of the spring with sonar. This sonar data helps create an accurate, three-dimensional map of Wakulla Springs.
