$The \'Door to Hell,\' also known as the Crater of Fire, is a natural gas field in Derweze, Turkmenistan, that collapsed into an underground cavern in 1971, becoming a natural gas crater. Geologists set it on fire to prevent the spread of methane gas, and it has been burning continuously since then. The crater is a popular tourist attraction. (Photo/VCG)$
