Text Description: Upper Pumice is 3-20cm thick and dark yellow-brown, a mixture of brown-beige pumice and dark gray-black scoria (42 wt% and 23 wt% of layer, respectively) and an abundance of non-vitric lithics (32 wt% of layer). Overall the PU lapilli are poorly sorted and vary in mean grain size (6-14mm) with the layer.
