The Manatee Springs Springshed is visible in both maps and was delineated in 2004.
Thanks to cave divers (Cindy Butler, Brett Hemphill, Annette Long, Mark Long, John Mosely, Andrew Pitkin, Mike Poucher, Sandra Poucher, Charlie Roberson, Bob Schulte, Marius Frei, Mark Singer, Matt Vinzant), 31,200 feet of the Manatee Springs cave system have been surveyed and documented. The cave system becomes visible when zoomed in on the Location map above.
