Summary:

Named for occurrence at type sections: walls of upper Olokele Canyon [22 deg 01' 15"N, 159 deg 36' 29"W, Waimea Canyon 7.5' quad], and of Poomau, Koaie, and Waialae Streams, tributaries of Waimea River, Island of Kauai. Consists of thick flows of olivine basalt, basalt, picrite-basalt, and rare andesite accumulated in broad caldera at summit of shield. Exposed thickness is 2600 ft near head of Olokele Canyon. Is separated from Napali Formation (new) of Waimea Canyon volcanic series by buried fault scarps. Is separated from Makaweli formation in part by fault scarp. Upper portion of Olokele formation is coeval with Makaweli formation. Is believed to be Pliocene(?) age, but stratigraphic chart has Pliocene.

Reference localities are walls of Poomau, Koaie, and Waialae Streams. Is considered older than Makaweli Member; is coeval with Haupu Member of Waimea Canyon Basalt. Assigned Pliocene age.
