Hell's Door
Kara Kum Desert, Turkmenistan
It has a beautiful view especially at night since its glow is visible miles away. This was a result during an excavation on 1971 for natural gas but the floor collapse like a sink hole and then the authorities decided to ignite the cave rather than letting the gas fume out and poison people. As a result a never ending glow due to a burning natural gas.
