A waterfall plunging over a trachytic lava flow is a popular tourist destination on Cheju Island. An extensive lava plateau underlies the Halla shield volcano and extends to the coast of the 40 x 80 km island. The volcano dominates the center of the island and has been active from the Pleistocene until historical time. Photo by Norm Banks, 1980 (U.S. Geological Survey).
