Highbanks Metropolitan Park Mounds I and II
The Highbanks Metropolitan Park Mounds I and II are two archaeological sites located within Highbanks Metro Park in the central part of the U.S. state of Ohio. The park is in southernmost Delaware County on the east bank of the Olentangy River. The subconical mounds are believed to have been built by the Adena culture.
Also located in the park is a semi-elliptical embankment, the Highbank Park Works, which consists of four three-foot-high sections bordered by a shallow ditch. It is thought to have been constructed sometime between 800 and 1300 CE by members of the Cole culture.
The site was surveyed by Ephraim George Squier and Edwin Hamilton Davis in 1846. They discuss the site in their 1848 book, Ancient Monuments of the Mississippi Valley.
