Seoseokdae (Mudeungsan Area National Geopark)

Seoseokdae (1,050m), located southwest of Cheonwangbong (1,187m), the highest peak of Mudeungsan, along with Imseokdae (950m), belongs to the Mudeungsan Columnar Joints, a Natural Monument. It is a representative attraction of Mudeungsan, where about 200 polygonal stone pillars, about 30m high and 1–2m wide, unfold like a folding screen. The rock composing the columnar joints is a volcanic rock named Mudeungsan Tuff, a welded tuff formed from volcaniclastic material erupted in the late Cretaceous Period of the Mesozoic Era (about 87–85 million years ago). As this tuff slowly cooled and contracted in volume, tensile stress acted to create the columnar joints. From here, one can view the cityscape and, in the distance, Wolchulsan, and the sunset reflected on Seoseokdae at dusk creates a spectacular scene.
