Spruce Hill Works is a hilltop enclosure encompassing 140 acres. Originally, the roughly triangular-shaped stone wall featured openings located at the northernmost point, along the western wall, and at the southeast corner. This southern opening was an elaborate configuration of three openings crossing an isthmus 700 feet wide. The Spruce Hill Works does not include any mounds, but represents another kind of ceremonial space.
