That is a very nice grouping of artifacts from a time period that is commonly misidentified. When I get back from this business trip I'll post a frame of Caborn-Welborn material from Southern Indiana. It was also a contemporary to the Ft. Ancient and went just a little bit later(to 1720 or so.)
What I think is fascinating about those groups (Ft. Ancient, Oneota, Caborn-Welborn, Monogahela, Oliver Phase, Springhills, etc.) is that they were really kind of the last wild Native Americans in the Midwest. With in a generation or so they were assimiliated, killed, or push west by other Native groups (as well as non- Native groups) that were moving in from the East.
