Crooked Creek crater

Crooked Creek is an impact crater in Crawford County, Missouri, United States.

It is 4.3 mi in diameter and the age is estimated to be 320 ± 80 million years (Mississippian). The crater is exposed to the surface.

This is one of the 38th parallel structures, a series of circular depressions stretching across the central United States, thought to possibly be the result of a serial impact.
