Papakolea - Hawaii's green sand beach.
This small, protected beach on Hawaii's big island opens to the east. This view shows the small, breached cinder cone that has yielded so much olivine to the beach. The basaltic tephra deposits are easily eroded producing sediments to the beach.
This view (looking south) is from
the talus slope that feeds the beach with sediments. Here the
stratification of the cone is obvious as well as the abundance of the olivine.
This view is from the south side of
the breached cone looking north.
