Early woodland pottery was the first pottery and is usually very thick and lacks ornamentation. Your piece is awful fancy for the early stuff. Are you sure that's limestone and not crushed mussel shell? Maybe it is EW...I'm not positive. Gary
Could be middle woodland; it is Candy Creek phase and it is limestone with the classic small holes where leaching has occurred. Candy Creek had quartzite temper (no leaching) and limestone temper (with leaching).
