But I really wanted to post a link to a very interesting site at MIT concerning Maritime Archeology.
15,000 years and before that, so much of earth's water was locked up in ice that the sea level was 400 feet or more BELOW present day's sea level. The ruins of cities have already been found off of both coasts of India at depths that would have been dry land 20,000 years ago, stone pyrmids just off the coast Japan (Okinawa) and I wouldn't be surprised if there weren't cities out in the bottom of the Caribean or out in the mid Atalantic.
Where does one read about that?

Will you be so kind and post this link again. I just saw it and it does not work anymore. Thanks.
