**Eternal flame***
This is an "eternal flame" -- nestled behind a waterfall in western New York state. It is one of a few hundred "natural" eternal flames around the world, fed by gas seeping to the Earth's surface from underground

Typically, this type of gas is thought to come from deeply submerged, ancient and extremely hot deposits of shale, a kind of rock. Temperatures have to be near the boiling point of water or hotter to break down the large carbon molecules in shale and create smaller molecules of natural gas. In this case, though, the rocks that feed the flame are only warm — "like a cup of tea" — as well as geologically younger than expected, and shallow.
