UNESCO Global Geopark
In the late Cretaceous Period of the Mesozoic Era (87 million years ago), when a volcano of Mudeungsan Mountain was exploded, the extrusive volcanic ashes and pyroclastics were spread out by water, wind, and gravity. With time, the volcanic ashes were accumulated and hardened to create volcanic stones (tuff) that were cooled and contracted for repeated times to develop pentagonal or hexagonal columnar joints. Living things of the mountain had been fossilized with the process of sedimentation, and columnar joints created the beautiful and mysterious sceneries of Mudeungsan Mountain.
The Mudeungsan area, known for picturesque sceneries and history of the Mother Nature’s long period of time, was certificated as a National Geopark in 2014 and UNESCO Global Geopark in April 2018. Loved by people around the world, the mountain continues adding a new page to its history.
