Viewing the Columnar Joints

Columnar Joint can be found along a 3.5km stretch of the Jungmun and Daepo Coasts, Jeju. The surface of the volcanic rock is rough with clinkers, but the mid-section of the lava units, exposed through erosion, forms a beautiful line of points like a landscape painting. In terms of size, the bigger points are up to 20m high; from top to bottom, they are clean and varied in shape. Found along eroded sea cliffs, they are mostly upright, although some are horizontal. Their upper sections are square or hexagonal. Due to erosion, the exterior is well-exposed; since they are close together, they look like an elaborate work of sculpture..
