High-level Description: Unit 2. Similar to Unit 1, comprised of smaller
accretionary lapilli (~2 mm) and coarse (3 cm) to fining-upwards (1 mm) blocky
angular to sub-angular grains. Accretionary lapilli are sub-rounded to
sub-angular and are light grey and composed of gritty ash. Other
lapillus-sized clasts are less uniformly-shaped than in Unit 1, with most
lapilli irregular, not spherical. Non-accretionary lapilli are larger (about 5
mm) and are white with smooth surfaces. There is no visible layering at this
scale, and accretionary and non-accretionary lapilli are evenly distributed,
with 80% of lapilli being accretionary. This layer also has an ashy matrix,
although it is still clast-supported.

Texture
  Grain morphology and appearance: Very angular to sub-angular grains mixed
with sub-spherical accretionary lapilli in a clast-supported matrix.
  Grain size and sorting: Well-sorted, fining-upwards clasts 1 mm-3 cm
diameter
  Grain fabric:  Random orientation.

Sediment structure:  None evident.

Color:  Black to grey.
