I visited the site for the first time last week. It struck me as being very similar to Fort Hill in Ohio. The main difference being the elaborate entry way created by earthworks at Old Stone Fort. Fort Hill lacks such a structure, perhaps because the entire site in Ohio is an isolated area where a creek cut through the neck of land connecting the area to a larger "plateau."
A small museum adjoins the site. You can camp and picnic on grounds across the Duck River from the hill fort and mounds.
Something is not right. This message is just to keep things from messing up down the road
