Just putting this up for research purposes. The Ais Indians salvaged many of the treasure ships that wrecked along SE Florida from 1500-1625. To date little has been found. I suspect much (if not all) of it lies at the bottom of Fisheating Creek (where they had another mound complex), sacrificed to the moon and sun gods.
