Unbelievable. This is the only word that can describe the phenomenon since ancient times can be witnessed in a valley located approximately 7 km walk from the Turkish resort of Olympus. This place is also known as Yanartas (or Burning Rock) and has a huge legend. The Chimera are spectacular flames SELF born (this is what is amazing) of rocky crevices on the slopes of Mount Olympus. Apparently, the flames are produced by a gas that burns upon contact with air. The precise composition of this gas is not yet known, but it is believed to contain some methane and thus produces flames. As cracks are plugged the fire disappears, but when it gets uncovered the flames arise again.
