Our field staff found these projectile points within inches of each other on a gravel bar within a stream. The larger lanceolate spear point is likely a "Guilford flat base" point from the Middle Archaic Period (5200-6000 years ago). The smaller is broken near the top so a tougher ID. It appears to be a type of stemmed or notched projectile from the Early to Middle Archaic Period, so these were potentially made hundreds to thousands of years apart from each other. Both pieces are made of rhyolite from the Carolina Slate Belt region.
