Darvaza, the 'Door to Hell'
Gas set alight 'for a few weeks' is still burning

The usual story is that in 1971 the ground collapsed under a Soviet drilling rig in the Karakum, opening a crater leaking methane. Geologists set it alight, expecting it to burn out in weeks, but the crater, about 70 metres wide, has been burning for decades.
