Mount Wingen in New South Wales, Australia, has been smoldering for 6000 years without stop. At around 100 feet below the surface of the mountain, a coal seam has been burning and slowly moving south at a rate of 1 metre per year. In its history, the seam has covered a total area of 6.5 km, making it the oldest continuous coal fire in the world. The coal was ignited by a lightning strike or brushfire thousands of years earlier. Although a popular tourist attraction, Mount Wingen or Burning Mountain has also caused massive ecological damage to the area’s vegetation.
