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.[1]
West Molokai overlaps the western flank of East Molokai Volcano, a much larger shield volcano comprising two-thirds of Molokai.
gollark: My "accursedsort" would work by:- initializing a counter to 0- repeatedly subtracting the smallest value from each element of the list and adding it to the counter- when a list item is 0, append it + the counter to a secondary list and remove it from the existing one- when list contains no items you are doneO(n) time*!
gollark: And that weird instruction for JS floating point conversion.
gollark: I think they have microcode in the newer core things now.
gollark: But it LIES.
gollark: I see.
