Dredging goes on at a limestone quarry that is also the location of the Haile 7G paleontological dig site. The dig site is the location of the Florida Museum of Natural History's "Tapir Challenge," which I joined as a volunteer on December 6, 2006. More about the "Tapir Challenge" is at:

(Close up the space before "6372" I can't seem to do it here.)
The water shown in this video is part of the Florida aquifer.
