Mastodon State Historic Site

1050 Charles J Becker Dr., Imperial, MO 63052 - United States




Mastodon State Historic Site contains an important archaeological and paleontological site – the Kimmswick Bone Bed. Here, scientists discovered the first solid evidence of the coexistence of humans and the American mastodon in eastern North America. Today, visitors can learn about this discovery and how the landscape of Missouri looked in pre-historic time. The site features a museum with an interpretive video, displays of ancient artifacts and fossils, and an impressive mastodon skeleton replica.


The museum includes displays, artifacts, exhibits and an interpretive video that reveal the secrets of the Kimmswick Bone Bed and help visitors understand the significance of the site. The impressive mastodon skeleton replica is a sight not easily forgotten. View a video that interprets the historic site. It is started every half hour during museum hours, with the last showing beginning 30 minutes prior to closing time.
