Mastodon State Historic Site is a publicly owned, 431acre archaeological and paleontological site with recreational features in Imperial, Missouri, maintained by the Missouri Department of Natural Resources, preserving the Kimmswick Bone Bed. Bones of mastodons and other now-extinct animals were first found here in the early 19th century. The area gained fame as one of the most extensive Pleistocene ice age deposits in the country and attracted scientific interest worldwide.The site was purchased by the state in 1976 following an effort to preserve it from destruction with the construction of Interstate 55. Archaeological history was made at the site in 1979 when scientists excavated a stone spear point made by hunters of the Clovis culture (14,000–10,000 years ago) in direct association with mastodon bones. This was the first solid evidence of the coexistence of people and these giant prehistoric beasts. The Kimmswick Bone Bed was added to the National Register of Historic Places in 1980.Activities and amenitiesA museum tells the natural and cultural story of the oldest American Indian site one can visit in the state's park system. A full-size replica of a mastodon skeleton highlights the exhibits. A picnic area, hiking trails, and a special-use campground offer chances to explore the land where the lives of Native Americans and mastodons once intertwined.Mastodon State Historic Site is just one of the many highlights you can arrange to see using our international travel planner, Imperial Edition.

We stopped only to go to the museum and not to do any of the outside things. The museum needs some sprucing up, but the information is interesting! The guide is overly excited to show you around which... more »

This is probably our new favorite place to hike! We did the Limestone Hill Trail. It was only about 1.5 miles and only had a short bit of up-hill - it was definitely a nice, easy hike! There aren't any look outs or any special views. But the walk is so simple and pleasant that it doesn't matter! There's also a playground and a shorter paved loop!

Short little hike is great for my young children. The visitor center has a great display of Paleolithic animals and humans to which my 2 year old describes very well as, "WOW!".

Very neat for us and kids. Family friendly and very educational. Nice hiking trails, no strollers

Loved hiking here! The trail is a good length for a short afternoon hike. Bring bug spray! There's a couple of water spots that breed mosquitoes, so be prepared. Other than that, I had a lot of fun - I'll be back :)
