Summary:

Named for reef and associated limestone deposit and undifferentiated lagoonal-deltaic sediments deposited during Waimanalo stand of sea, southeast part of Island of Oahu. [Type locality not stated] Consists of cream to grayish-white reef (37 ft) deposit of coral, coralline algae, mollusk shells, Foraminifera, and other reef-building organisms; lagoonal-deltaic facies (40 ft) consist of light-gray, fine, calcareous sand containing basaltic grains. Unconformably overlies Bellows Formation (new). Unconformably underlies deposits of late Pleistocene age. Assigned Pleistocene age based on Transgression III (Sangamon).
