Most ballast stone piles occur in about 18 feet of water, or less. In and around the stones will be encrusted bronze spikes or iron and bronze bolts. Look for objects that have straightness. On the ocean floor few things occur naturally straight. Most of the Spanish galleon stones are smooth and tend to be spherical, probably from the erosion that occurred in the european river beds from which they originated--but some are huge and irregular. So you will know they're ballast stones by the company they keep!
