This park includes a very well done museum which includes amazing prehistoric Indian artifacts, like effigies of falcons, beavers, and other animals, as well as tools the Hopewell Indians used. The ranger in charge of it showed us a 20-minute documentary to introduce us to the Hopewell culture and their mounds, which was very well done. The mounds are very well preserved, and include excellent signs with explanations. There is also a store where you can buy books, videos, and other interesting materials to help you better understand the Hopewell culture. A must see for children and adults.
