Longest Underwater Cave in North America Mapped
On December 15, 2007, divers Casey McKinlay and Jarrod Jablonski completed a traverse from Turner Sink to Wakulla Springs, covering a distance of nearly 36,000 feet, or 6.8 miles. This is a world-record long underwater dive on air! The traverse took approximately 7 hours at depths up to 300 feet, followed by 15 hours of decompression. The connection of the two cave systems resulted in the longest mapped underwater cave in the United States and the fourth longest in the world, totaling 169,000 feet or 32 miles! Further exploration is only limited by current technology and the lack of additional known cave entrances.
