Point on the left looks to be a Savannah River, not sure on the middle one, right piece looks to be an unfinished preform judgin` from the pic. I would think they are Archaic pieces. As far as tribe, we have no idea what these people called themselves, but they were there long before the Creeks moved into the area. I`d sure go back there after it rains and look some more.
Jaybird huh? We used to go there when I was a youngun. They had the first cement pond (swimmin` pool) I ever saw!
