The two shell middens excavated by Smithsonian workers, Wedel's Sites 1 and 2, were also located within this occupation zone and were undoubtedly the two largest and probably most important concentrations of midden along the two mile stretch. Wedel's Site 1 is at the approximate midpoint of the two mile stretch adjacent to a major drainage, while Site 2 was at the extreme eastern end of the stretch on a long, narrow sand bar.
