The site covers over 2,500 acres and features hiking trails that allow visitors to explore the mounds and learn about their historical significance. The monument is not only important for its archaeological value but also for its natural beauty. It encompasses diverse landscapes, including forests, prairies, and river bluffs, providing habitats for various wildlife. The site is managed by the National Park Service, which aims to protect and interpret the cultural and natural resources for future generations.
