This large earthwork complex contains a low embankment forming a small circle and an irregular circle and a square, all connected and enclosing about 121 acres. Within the enclosure is a large elliptical mound, three smaller conjoined mounds, several small mounds, and several structure outlines found through excavations. It is estimated that the large mound was originally 240 feet long, 160 feet wide, and 30 feet high.
