scattered throught: so light gray to white
on fresh surfaces, with darker coloured lenses
where carbonaceous matter present more or less
sparsely: only locally resistant weathering: lighter
gray with yores of iron stain.
cgl marks channel bottoms? at locality
measured: 2 pronounced cgl layers: one
at top: one at 5' from top: bottom layer
thicker, contains frags. of chest and so
mostly so & chest + grits in cgl.
Disconformity - the big one
3'->4' silty clay: weathered section shows
varicolored silty clay w/ pinky greens/b
brown yellow gray layers in that order:
becomes more silty in lower part where
layers of silstone are interfedded
with fine grained sandstone. This appears
to be a local disconformity at the top of
this interval. Buttwel!
