Measured strat columns of Keanakakoi Ash Member, which was deposited between
1500 and 1790 CE. Each group recorded thickness, bedding characteristics,
sorting, composition, and color (using the Munsell chart) of the sub-units. At
the base of the column was a basalt layer, followed by a vitric base. The
Keanakakoi Ash consists of several layers of ash and lapilli with a lithic-rich
layer near the top of the column. The uppermost layer is a breccia, consisting
of occasional block and block sags.
