Contest #184 answer: Burning crater near Darvaza, Turkmenistan

In 1971 some geologists were drilling to gas in the Darvaza area of Turkmenistan.
The ground collapsed as they were drilling on top of an underground cavern which was filled with natural gas. They decided to burn the gas in order to gain access to the cavern, but now, 40 years later, the fire is still on.
This burning crater (a.k.a. ‘The Door to Hell‘) is on the internet on some sites wrongfully placed in Uzbekistan, so I approved the ‘Uzbekistan-answers’, but the correct location is in Turkmenistan.
