George, I know diving is the subject here, but the results of your dives seem really fascinating. Not the penetrations, but what you see where man once walked. Are you, or is anyone in your group, writing anything about lowered sea levels. Specifically what Florida may have looked like 10,000 years ago or even 20,000 years ago, and how the topography of that time may have appeared. I tend to think of man as moving to high ground for safety, but Florida may have been a vast plain with caves 200 ft. down in sinks being the best shelter. While saber-toothed tigers roamed above.
