TIL A coal seam in Australia is believed to have been burning for 6,000 years, making it the oldest coal fire. The site's name is Mount Wingen but is commonly called Burning Mountain and the fire is traveling south 1m per year discoloring the ground as it goes.

My whole yard is coal wash from a nearby mine. Two years ago when the PNW had that really bad summer where it got to 114 degrees we had a fire start in the yard. We got it taken care of and started looking for the source. Using our excavator and some kind of a heat vision thing we dug into a really hot spot underground. Dude, the dirt in the pit we dug was fucking boiling. It's normally a thick black mud out here, but it looked like bubbling black sand. Like I was boiling ink.
I'm not sure what started it, it could have been burning for years and the drout is all that was needed to set the lawn on fire, but it was spooky man.
