Summary:

[Named for] Waiokamilo Stream valley. Cascades down cliff at E edge of Keanae Valley building small fan. Included as unit of Hana volcanic series. Composed of dark-gray olivine basalt with few phenocrysts of plagioclase up to 5mm across. Unconformably overlies Honomanu and Kula volcanic series.
