High Bank Works
High Bank Works consists of multiple earthen features spread over 197 acres on a terrace above the Scioto River. A circle and octagon, each measuring approximately 1,000 feet in diameter, are major features of this site. On the interior of the octagon were eight small mounds that correspond to the eight intersecting points of the outer walls. Six of the intersecting points form gateways, and one to the north forms an entrance into the large circle. The large circle has one gateway to the east and is opposite a smaller circular enclosure 250 feet in diameter.
Beyond the southern most point of the octagon were two small circles, each 300 feet in diameter, with single gateways. They were connected to the larger forms by two nearly parallel embankments extending southwest for almost 2,000 feet. Three small conjoined enclosures were located at the far end of the parallel embankments.
