This highly enjoyable 60 minute video, led by Wes Skiles and shown on PBS across the nation, is perhaps the finest explanation of the relation of karst to groundwater as supremely illustrated in the Floridian aquifer. Sensational cave diving combined with extremely effective conservation. All this and humor, too! 2003, Karst Productions. Water's Journey Special Edition DVD Includes the full documentary plus short film features, Expedition highlights and Florida Springs interactive Learning Site.
