Yongduam means Dragon Head Rock. It is a volcanic coastal rock formation on Jeju Island that resembles a dragon's head, and local versions of the story describe a dragon or serpent-like being frozen into rock near the sea.
Travel sources describe the myth as a dragon struck down while trying to take a sacred jade stone from Mount Halla.
