High-level Description:  Scoria, sub-angular to sub-round. Scoria have black
rims that may be a result of weathering, since clasts under the black coating
are tan. There is also white precipitate on many clasts. Scoria are fairly
vesicular, with some large vesicles, although none are more than 1 cm in
diameter. Some scoria clasts are up to 3 cm, but most are 1 cm or smaller.

Texture
  Grain morphology and appearance:  Angular to sub-angular scoria, black with
some red fragments. There is also significant amounts of white precipitate,
which is mostly concentrated on black scoria clasts. Ash is light grey and
very finely laminated. There is also some white precipitate on the ash layers.
The contact between the scoria and ash (img 3790) is bumpy, and some smaller
scoria are incorporated into the top layer of the ash. Some of the top layer
of ash is also interrupted by larger scoria fragments.
  Grain size and sorting:  Scoria fragments are 1-5 cm in diameter; grains
below this layer are sub-mm in size.
  Grain fabric:  Random orientation.

Sediment structure:  Very fine parallel lamination present below the coarse
scoria layer. Image 3790 shows a bomb sag.

Color: Black to tan with several red clasts
