High-level Description: Tuff consisting of sub-angular, glassy, scoria clasts
and a few smooth white clasts in a glassy matrix. Clasts can be divided into:
(1) large, frothy sub-rounded, rough clasts from 0.8-5.4 mm in diameter,
averaging ~1.5 mm (70%); (2) smaller, smooth, sub-rounded grey to white clasts
~1.0 mm in diameter (20%); and (3) very small brown, round, rough-textured
vitreous clasts ~0.5 mm (10%). Vesicles in these clasts are up to 0.7mm in
diameter. Scoria are sub-angular to sub-rounded, and are from 0.3 mm-1.7 mm in
diameter. Matrix grains are round, smooth, and glassy, with an average size of
0.1mm.

Texture
  Grain morphology and appearance: Sub-rounded to sub-angular sub-vitreous to
vitreous clasts in a fine, light red-colored, clast-supported matrix. Clasts
include frothy and vesicular, smooth and rough-textured clasts.
  Grain size and sorting: Clast sizes vary from 0.5 to 5.4 mm in diameter.
Poorly-sorted.
  Grain fabric:  Random orientation.

Sediment structure:  None evident.

Color:  Dark brown, white and black grains in a light-red/tan matrix.
