Mastodon State Historic Site, Paleontological excavation site in Imperial, Missouri, United States
The Kimmswick Bone Bed contains numerous Pleistocene ice age deposits with mastodon bones and other extinct animal remains within its 425-acre grounds.
Scientists discovered a stone spear point from the Clovis culture in 1979, confirming interaction between humans and mastodons between 14,000 and 10,000 years ago.
The museum displays a full-size mastodon skeleton replica, ancient artifacts, and fossils that represent the earliest documented Native American location in Missouri's park system.
The site features three different hiking trails ranging from 0.5 to 2.25 miles in length, plus picnic areas and a special-use campground for organized groups.
The Kimmswick Bone Bed represents one of the largest Pleistocene deposits in the United States, containing extensive collections of mastodon and prehistoric animal remains.
