This place has been burning for 40 YEARS!
“Fearing the release of further poisonous gases from the cavern, the scientists decided to burn it off. They thought that it would be safer to burn it than to extract it from underground through expensive methods. Environmentally, gas firing is the next best solution when the circumstances are such that it cannot be extracted for use. At that time, expectations were that the gas would burn within days, but it is still burning, more than four decades after it was set on fire.”
Sounds like Crosstex . . .
