This used to be an old parking lot

With the help of a Native American monitors I found site material just below the surface

This site is not intact. It has been taken from another spot and dumped here.

After examing the stratum of site material, we observed small fragments of shell but no bone. Our best guess is that this site was removed from its original location and dumped here years ago to serve as dirt fill to build the parking lot. I bet that if the machines dug deeper, they would fin intact site material.
