High-level Description: Two layers, an accretionary lapilli-rich ash and ash
layer. Ash balls are mixed with smaller, angular to very-angular grains.
Lapilli are sub-spherical and average 2-10 mm diameter. Accretionary lapilli
occur in a matrix of coarse black/white (0.18-0.4 mm) and finder-grained grey
ash, with size decreasing upwards.

Texture
  Grain morphology and appearance: Sub-spherical accretionary lapilli grains
with granular texture mixed with angular coarse ash.
  Grain size and sorting:  Coarse ash <=0.18 mm supports accretionary lapilli
2mm to 10 mm in diameter, increasing upwards in size.
  Grain fabric:  Random orientation.

Sediment structure:  Graded bedding.

Color:  White/black and grey grains.
