The Washington Post highlighted a University of Cincinnati archaeology discovery of evidence that a near-Earth comet devastated Native American settlements in the Midwest more than 1,500 years ago.
UC College of Arts and Sciences anthropology professor Kenneth Tankersley led a team of biologists, anthropologists and geologists who took sediment samples at 11 known ancient Hopewell sites in the Ohio River Valley stretching across three states.

The surveyor found Hopewell mounds standing five to 10 feet tall, including one in the shape of a comet. The site had previously been surveyed in 1803. Map/National Archives
