But there are more than just fossils to be found at Fort Drum! Look at this piece --- one of Eddie's favorites. It is a fossil clam that has been partially disolved away and then partially filled in with AMAZING calcite crystals. I have seen fossil clams with calcite in them before, but never such big clams and especially not such big calcites! And look at the COLOR! People are actually faceting broken pieces of this calcite it has such good color.
