Coordinates: 40.252501987265276, 58.43959946915778The"Gates of Hell," also known as the Darvaza gas crater after a nearby village, is a methane- and fire-filled crater in Turkmenistan's desert.
Shortly after the crater opened, Soviet scientists set its walls alight, thinking the fire would burn off the methane within a few weeks before dying down. But instead, the fire kept burning. The crater is likely connected to stores of flammable methane gas that provide seemingly unlimited fuel for the fire.
