The Gates of Hell in Turkmenistan
Deep in the Karakum desert in Turkmenistan lies something extraordinary: a 230ft-wide hole with fire in it. Known to locals as “The Gates of Hell”, the crater (officially known as the Darvaza gas crater) was the result of a disputed accident:
[…] a Soviet drilling rig accidentally punched into a massive underground natural gas cavern, causing the ground to collapse and the entire drilling rig to fall in. Having punctured a pocket of gas, poisonous fumes began leaking at an alarming rate.
To head off a potential environmental catastrophe, the Soviets set the hole alight, figuring it would stop burning within a few weeks. Decades later, and the fiery pit is still going strong. The Soviet drilling rig is believed to still be down there somewhere, on the other side of the “Gates of Hell.”
The hole has been on fire for 40 years. For more pictures and the story of a Canadian explorer who went down, check out this Guardian article.
