Geology
It was formed in two volcanic phases during the Pleistocene epoch of the Quaternary period in the Cenozoic Era.
The first formed the broad tholeiitic shield volcano of West Molokai that ended 1.89 million years ago. The second volcanic phase produced postshield alkalic volcanics 1.76 million years ago.
West Molokai overlaps the western flank of East Molokai Volcano, a much larger shield volcano comprising two-thirds of Molokai.
