Woodwille Karst Plain Project – Jarrod Jablonski and Casey McKinlay - entered Turner Sink in the Leon Sinks and after 20 hours came out in Wakulla Springs. Dive itself took 6.5 hours, 14 hours were necessary for decompression after diving 90 m deep. There was no possibility to come to the surface in between – thus this was truly astounding accomplishment with very complex support system.
Thus there were connected several large cave systems and the largest underwater cave system in United States was discovered. Since then researchers have managed to extend the knowledge and now the known total length of passages is fantastic: 51,483 m!
By far not all is explored yet. Not too far is Chip’s Hole – more than 5 km long cave system and several more cave systems.
