While sinkholes as big as the one that swallowed eight Corvettes in Bowling Green last week aren't typical, smaller ones are common in the area.
Western Kentucky University geology professor Ken Kuehn says it is "a very typical feature of the karst environment."
Kuehn says that environment extends from around Elizabethtown to Tennessee.
Warren County Public Works Director Mac Yowell says his department gets calls weekly about sinkholes. He says the sinkhole at the Corvette Museum was one of at least five recorded in the area last week.
