'It was a bad day for Peoria County about 450 million years ago'

 Charles Monson recently published a study revealing a possible link between a meteorite impact crater found in Illinois and a 93-mile-wide asteroid that broke apart 466 million years ago. "A meteorite bigger than the State Farm Center hit near the present-day Village of Glasford, a little ways southwest of Peoria. It created a 2.5-mile-wide crater that we now call the Glasford structure," Monson explained.
