When it comes to sinkholes, Kentucky ranks number seven in the nation.
In fact, there are thousands of sinkholes across the state.
An expert from the Kentucky Geological Survey says he can predict what areas of the Commonwealth are most likely to have sinkholes.
He says the reason for this phenomenon is Kentucky's karst areas---meaning rocky ground.
"It literally means rocky ground," James Currens said, Hydrologist. "Between the limestone and the dolomite about half the state is underlain by the soluble rock."
The most famous is the recent sinkhole at the National Corvette Museum in Bowling Green.
