High-level Description: Unit 5b. Fine-grained unconsolidated palagonitic layer
within unit 5. Unit is composed of brownish, small sub-spherical grains (less
than 1 mm, averaging ~0.5 mm) and other sub-angular to sub-rounded clasts
(<0.1 to 0.3 mm), some of which are black angular glass, but many of which are
light brown to white grains with smooth to pitted textures. There is no clear
layering, but fine grains near the top of the photo grade into slightly larger
grains toward the bottom.

Texture
  Grain morphology and appearance: Small, sub-angular to sub-rounded,
palagonitized grains in a clast-supported matrix. 
  Grain size and sorting: Poorly-sorted clasts 0.1-0.5 mm diameter.
  Grain fabric:  Random orientation.

Sediment structure:  None evident.

Color:  Light-brown and white grains mixed with black glassy particles.
