Summary:

[Named for] village of Keanae, N coast of Island of Maui. At 1300 ft covers entire floor of Keanae Valley, but farther N it divides into 2 branches, one followed E wall of valley and the other the gulch of Piinaau Stream. At coast forms lava delta on which village of Keanae is located. Included as unit of Hana volcanic series. Composed of dark gray olivine basalt with phenocrysts of olivine and augite. Underlies sedimentary rocks of Pleistocene and Recent age; overlies Waiokamilo basalt (new), Piinaau basalt, Ohia basalt (new) (all of Hana volcanic series) and unconformably overlies Honomanu volcanic series (new). Map shows middle(?) and late Pleistocene and Recent age.
