10. Mastodon State Historic Site

Sure, it’s not a "true" State Park, but Mastodon IS a designated Missouri historic site, and it’s definitely worth checking out. This area is a significant archeological and paleontological site that preserves the Kimmswick Bone Bed, where the fossilized bones of mastodons were discovered in the early 19th century. This is also the site where archaeologists uncovered the famous Clovis-point spears that greatly influenced the way we understand the life and spread of culture in prehistoric eras.

At Mastodon State Historic Site, there is a museum that offers TONS of information about the history of this area, including stories of the culture of the oldest Native American site in the entire state! The Museum also has incredible exhibits featuring the full skeletons of mastodons and other now-extinct creatures that once called this area home. There are also recreational activities offered here, including a lovely picnic area and three hiking trails to explore. The two-mile Limestone Hill Trail is quite rugged, with steep climbs through rough terrain, but the views of the Sekman Valley from the top of the bluff are absolutely worth the extra effort. The shorter Wildflower Trail (0.4 miles) is easier (yet still rated moderate), takes you down a wooden staircase to the Kimmswick Bone Beds where the first fossil discoveries were made. Interpretive information along the way help paint a beautiful picture of what life was like here thousands of years ago!
