 Illinois Governor J.B. Pritzker is calling on a federal agency to address the effects from a sinkhole that opened up this week in Gordon Moore Park in Alton. Here's the Big Z's Mark Elibrock. 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.
