The people of Turkmenistan call it "Door of Hell". It is also said to be made of a few people. The story came, some were looking for geologist. Suddenly all the equipment, including all the equipment, went downstairs. Then they discovered this huge gas hole. Not too long, 40 years ago. So they thought that because the hole is gutted and if the gas is extinguished, then they will dig it down or see if the gas is below the grain. They did not have too much gas down, but this huge intake of ovens has been burning for almost 40 years by proving that all experts are wrong.
