Someorioreum Volcanic Cone (Udobong Peak) (쇠머리오름(우도봉))

This volcanic cone forms the head of Udo (the small island), and the residents of Udo call it 'Seommeori.' The southeastern slope plunges into the sea, forming 100-meter-high coastal cliffs, while the northern slope leads to the gentle lava plateau of Udo Village, shaped by past lava flows. It is a subaqueous tuff ring, and Mangdongsan, a crater rim known as Aloreum, rises in the center of the crater.
