If Golden clouds be best
at all times may be here.
dark gray. Varies in thickness laterally,
silty claystone with local thin beds siltstone
grades to argill. siltstone - whole with punched
conch fracture.
9.0
Interbedded massive fine grained light gray
sandstone (argillus high) and argillaceous siltstone
and fine ss (weths bluegray). Interbedding
irreg., most common top and lower 2 feet where
float fragments to slowly, shaley is to silty shale.
Later dk gray with blunt cross.
Altho local discont betw. this & ss below they
are similar - espec. where 'argillaceous beds of
this unit punch out laterally - as they do.
Sandstone, fine grained to silty, laminated,
similar to above & locally continuous with it, tho above has silty clay ptgs
& this doesn't.
Both not very resistant but loc. worth to
bluffs on slope, typically laminated, with
cross lam. minor, upper part pitted where
clay worn out. Worth col light gray
with yellow stain on some with bedding.
5.8
Interbedded silty shale, dk gray, with shaley siltstone
Siltstone in thin beds highly festened, locally beds
faintly hard siltstone up to .3.
slope wash Above interval represents only upper
part of shaley siltstone unit at base of
continuous exposures end there.
Supplementary section - About 100 ft along strike NW of
road side exposures. Mtrs. from base of ss unit (9.0+13.0)
shown above,
(9.0+13.0)
Sandstone
14.0
Interbedded silty shale & siltstone, as above.
Upper 9'2 covered by slope was lower H:8 as
above becoming more shaley downward.
