Geupsudae Columnar Joints

The representative rock that makes up Juwangsan National Park is tuff. Tuff is a rock formed when volcanic ash ejected during a volcanic eruption piles up and hardens. Columnar joints are geological structures where rocks are split into pillars, and are formed when volcanic rocks contract during cooling. The columnar joints at the water station are a place where you can observe the columnar joints developed in the tuff, and together with the tuff cliffs of Juwangsan Mountain, they form a unique geological landscape.
