High-level Description: Unit 14. Draping mixed, lithified tephra. Abundant
primary scoria (well-cemented, poorly-sorted) and larger, blocky lithic clasts
(15-20%) with less coarse ash interstitial (img 3949, 3950). Grain supported
blocks and bombs are also present. Juvenile fragments were plastic when
deposited. Small vesicles throughout. Coarse draping scoria overlies this
unit, at an unconformity (3947, 3948).

Texture
  Grain morphology and appearance: Varied basalt scoria grains in a
clast-supported matrix (img 3951, 3952). Most grains are angular to
sub-angular and very rough-textured. Some show textural evidence of plasticity
during emplacement. Tan finer grains are interstitial.
  Grain size and sorting: Poorly-sorted; grain sizes range from 2-10 mm,
averaging 5 mm. Some grains are as large as 5 cm.
  Grain fabric:  Random orientation.

Sediment structure:  Parallel and cross-bedded lamination.

Color:  Black and buff scoria grains, with a few red and green-clear grains.
Less coarse grains are tan.
