**Fort Hill State Memorial Located in Southern Ohio just a few miles away from Serpent Mound is a nature preserve containing one of the best preserved Indian hilltop enclosures in North America. The Hopewell Indians (100 B.C.-A.D. 500) constructed the 1 1/2 mile long earthwork hilltop enclosure as well as at least two ceremonial buildings and probably a village in the Brush creek Valley. Lying at the western edge of the Allegheny Plateau, immediately south of the glacial boundary, this hilly area contains an impressive diversity of bedrock, soils, flora, and fauna. There are 11 miles of hiking trails at the 1,200 acre preserve as well as a picnic area. This picture is a doorway of an older sandstone building in the picnic area. ** 20% of my profit on all Fort Hill related prints will be donated to the Fort Hill Historical Preservation.
