Songdaeso Columnar Joints
- Location 707-15, Guntan-ri, Galmal-eup, Cheorwon-gun, Gangwon-do
The shapes of the columnar joints located in Songdaeso were made through vertical splitting as the hot lava cooled down and its volume decreased. In general, the shapes of a pentagonal or hexagonal column are common. Cheorwon is the only place in Korea where basalt flows along an old river, and the basalt is made into a cliff as the river split it yet again. Cheorwon’s vertical red wall boasts a height of 30 meters over everything, and its harmony with the jade-colored water of the Hantangang River, which looks deeper than the height of the cliff, takes your breath away.
Additionally, the view of the blue sky and its reflection that can be seen as you walk upstream along the frozen Hantangang River as well as the scenery of the gorge that harmonizes well with the winding Hantangang River adds mystery and wonder.
