August 1997 - Bathtub Spring is a little spring on the Suwannee River, now overlooked by a large house. This was my second major cave map, and it was drawn all by hand. Michael Poucher assisted with the survey, and Brett Hemphill tried to follow me to the end of the line, with a single y valve aluminum 40 tank. We have not been back. A total of 1030 feet was explored and surveyed. Original map is available through the NSS-CDS.
