Burning Hill

 

Yanar Dag (aka.. Burning Mountain, Pilpia, Bozdagh, Ahtarma, Gaynarja), located in Azerbaijan along a hillside near Baku and the Caspian Sea, is a never ending gas fire.   The hillside shoots out flames of almost 10 feet from it's thin, porous sandstone layer.  It has a steady stream of continuous gas that allows it to constantly burn. The hillside caught fire when it was accidently lit in the 1950s by a shepard and has yet to be extinguished.
Apparently the smell of gas (hydrocarbon gas) is found in the area and local streams nearby can literally be lit with a match.  These local springs are known as "burning springs".  These springs are used for curing ailments by the locals.  The hillside burns in colorful flames most prominently at dusk and is a obviously a unique tourist destination.
