Columnar Joint in Yangnam, Gyeongju

The columnar joints of Yangnam, Gyeongju are clearly distinguished from other columnar joint formations already designated as natural monuments elsewhere, both in the scale of their development and in the size and variety of their forms; above all, they include large-scale horizontal columnar joints, among them an unusual fan-shaped formation. They are more than adequate as research and educational material for a comprehensive understanding of the cooling process and characteristics of volcanic rock, and they provide useful academic data for understanding the formation of the East Sea.
