Located in Turkmenistan’s Karakum desert, the Darvaza crater is a massive man-made sinkhole that has been leaking methane gas for decades.

It has been said that it was intentionally set alight by Soviet authorities, hoping it would burn off in a matter of weeks. However, nearly 50 years later, the crater is still burning and its true origins are still shrouded in mystery.
