Kaʻala or Mount Kaʻala (pronounced [kəˈʔɐlə] in Hawaiian) is the highest mountain on the island of Oahu, at 1,227 metres (4,026 ft). It is a part of the Waianae Range, an eroded shield volcano on the west side of the island. The FAA maintains an active tracking station at the summit, which is closed to the general public and secured by the US Army which is stationed at the base of the mountain, at Schofield Barracks. The tracking station can be clearly seen from afar as a white, domed-shaped structure.
