Mastodon State Historic Site preserves an Ice Age bone bed
Near Imperial, a state historic site preserves the Kimmswick Bone Bed, where Ice Age mastodon remains and early human artifacts were found together, a nationally significant site.
Mastodon State Historic Site near Imperial preserves the Kimmswick Bone Bed, a place where the bones of Ice Age mastodons were found, and where evidence of early (Clovis-culture) human presence was documented alongside them. The site includes a museum and is a tangible link to Missouri’s deep prehistory. Missouri State Parks interprets it and is the authoritative source for what was found and what it means. For a visitor or new resident it is an unusual and genuinely significant stop, connecting Jefferson County to the last Ice Age and the earliest people in the region.
