Des Plaines crater

The Des Plaines crater or Des Plaines disturbance is recognized as an impact crater in Cook County, Illinois, United States.

It is located beneath the eastern part of the city of Des Plaines, which is a suburb of Chicago.

[4] The crater is buried beneath 75 to 200 feet (23–60 m) of glacial till and can only be seen as a series of faults and deformations in well logs and seismic surveys.

[3] Subsurface strata of Cambrian through Pennsylvanian age has been faulted and tilted by the event.

[5] The upfaulted central portion[5] and the presence of shatter cone structures support the impact origin.
