Darvaza
is a town in Turkmenistan, a nation that borders Iran and Afghanistan.
The locals call their amazing geological wonder The Door to Hell. This
hole in the ground has a never ending supply of burning gas. The story
of its formation claims that more than 35 years ago geologists drilling
for gas in the area dug too deep and the ground caved in. The geologists
dared not go into the hole to get their equipment. Afraid that
poisonous gas would come out of the hole, the geologists set fire into
the hole and that fire has just never gone out.
