Sleeve of Armor Rock Formation
Erosion exposed this large cliff of rhyolite and dacite. It stands 65 meters high on the eastern side. Sheets of rock developed into columnar joints running for some 200 meters. At the top of the triangular cliff wall one finds a seemingly countless number of these columnar joints and platy joints. Their resemblance to the armor that covers a warrior's arm led to its name. Distinctive rocks here such as Hawk's Nest Rock and Bee Hive Rock were eroded into shape by waves.
