Dr. Jim Hower, UK CAER Geologist/Scientist and Dr. Jen O'Keefe, Geologist/Scientist at Morehead State University were interviewed by WLEX 18 for Mystery Monday: Mystery Of Underground Coal Fires.

From WLEX: Scientists say there are at least 30 underground coal fires in Eastern Kentucky, mostly in old abandoned mines. One of these burns under Highway 80 in Perry County. It's known as the Ruth Mullins fire and scientists are concerned that most people don't know how dangerous these fires can be.
