 Illinois Governor J.B. Pritzker is calling on a federal agency to address the effects from a sinkhole that opened up in Gordon Moore Park in Alton. Here's the Big Z's Mark Ellerbrock. Wednesday's collapse didn't result in injuries, but Pritzker's office said it was caused by a previous mining operation in the area and falls under the jurisdiction of the U.S. Department of Labor's Office of Mine Safety and Health Administration.
