During one of the heavy rains this summer, a motorist in Pike County was killed when he drove into an area of roadway that had collapsed. A couple of years ago, a golfer in southwestern Illinois escaped serious injury when the ground collapsed underneath him and sent him into a 20 ft. crevice. They were both the result of sinkholes, which can occur naturally in some parts of Illinois and can occur elsewhere due to man made causes.
Bill Wheelhouse discussed sinkholes in the state with Sam Panno of the Illinois State Geological Survey.
