This park is named after the little-understood Copper Culture people; so named because we have little more information about them other than their use of the metal. The park boasts a few varied trails that stretch throughout the area. A few trails go through what is though to be a massive mass burial pit of the Copper Culture that could be older than 5000 years! It was sobering to consider but also fascinating. The trail led to a very nice spot along the river. Unfortunately, I don't believe camping was allowed on site, which is why I removed a star. Definitely a good and interesting spot for the history buff or for a nice day trip.
