Mastodon State Historic Site contains the Kimmswick Bone Bed, a paleontological site listed on the National Register of Historic Places. Archaeological excavations established that Paleo-Indians hunted the American mastodon and other animals here during the ice age. The museum displays ancient artifacts, fossils and a mastodon skeleton replica. The museum and exhibits may be toured for a nominal fee. The 425-acre site is open for day-use activities, such as picnicking and hiking.
