More points from Rhode Island

Reader Joshua H. writes:

I found these points recently at Rome point in North Kingstown, Rhode Island. I think I found a clovis or angostura point made from quartzite as well as a broken quartz meadowood point, Cobbs triangular made from purple red rhyolite and koens crispin point made from argillite.  All found far from the water where the river systems meet the sea in the wash out where the tidal pools meet the highest point of the beach.  Any help would be appreciated.
