descent into hell...
The Darvaza Crater in Ahal Province, Turkmenistan, is known as the “Door to Hell.” The story goes that Soviet petroleum engineers created the hole in 1971 while looking for gas. The collapsed crater spewed dangerous gas, so they ignited it, thinking the gas would soon burn off. Over forty years later, the crater is still burning.
In 2014, explorer George Kourounis descended to the bottom of the crater, protected by a fireproof suit. Even he was surprised by the heat of the crater. Kourounis didn’t stay long, but he brought back biological samples from the bottom.
