The southeastern coast of Jeju near Goseong-ri in Seogwipo-si stretches under a high October sky, the sea presenting itself in the graduated blues that characterize Jeju's deeper offshore waters where the East China Sea basin begins its descent. The coastal geology here shows the classic Jeju pattern of columnar jointed basalt, dark hexagonal pillars formed by the slow cooling of ancient lava flows that now serve as natural breakwaters against the Pacific swells. Wind-shaped textures on the water's surface record the passage of the northeasterly breeze that typically accompanies clear autumn weather on Jeju, replacing summer's humid southwesterlies with drier air from the Korean mainland. The vertical composition draws the eye from the dark volcanic foreground through the transitional nearshore zone to the vast expanse of open ocean beyond.
