The Decaturville crater, also referred to as the Decaturville Dome, is an impact crater in Missouri, United States, and is one of the 38th parallel structures.
It is 6 km in diameter and the age is estimated to be less than 300 million years (Permian or younger). The crater is exposed at the surface.[1]
The effect that this impact had on the surrounding bedrock can be seen in a roadcut that runs along highway 5 about 16 miles north of Lebanon.
