Just some stuff I've saved over the years. Wondering if it is anything. The arrowhead looking item was found at Lake George, New York. Everything else came from the Chesapeake Bay area in Calvert County Maryland.
Gator is the man for coastal finds. I'll tell you, I would have saved those finds too. The brown stone pieces may be concretions but I don't think they are. It looks like wear on one of those, at least, to me it does.
