High-level Description: Proximal scoria deposit. Fragments are poorly-sorted,
sub-mm to 10 cm in diameter. Scoria is glassy, frothy and vesicular, with some
fragments stretched and broken. Gradations appear in vesicular density and
fragment size; larger fragments are similar to spatter in texture.

Texture
  Grain morphology and appearance: Dark black, glassy, or tan-brown frothy,
very angular vesicular fragments.
  Grain size and sorting: No individual grains. Fragments average sub-mm to 10
cm in diameter and are poorly sorted.
  Grain fabric:  No individual grains can be seen.

Sediment structure:  None.

Color:  Dark black, glassy, with brown-tan surface coatings.

Comparison:  Compare to images 3775-3778 where scoria are non-vitric,
crystalline but with no phenocrysts, displaying a low level of vesicularity.
Compare to proximal Kilauea Iki deposit in images 3845-3866, where morphology
is more frothy and les vitric, clast sizes are more mixed (sub-mm to 10 cm)
and exteriors are less glassy. Additionally, the proximal deposit has a
bimodal vesicle distribution (large/small).
