Looking to take a trip to where something big happened? Try Mastodon State Historic Site. The site is the home of the Kimmswick Bone Bed, one of the most famous and extensive Pleistocene ice age deposits of fossils, including a number of bones of giant mastodons. Interpretative trails and picnic sites dot the landscape and a museum tells the natural and cultural story of the Clovis culture, which existed in the area between 10,000 and 14,000 years ago.
