above disconformity.
Morrison contact fairly well-defined
2" type Cloucrly by presence of
chert pebble (dom, gray + black) cql.
Although this locally pinches out,
Below this cql section varies,
may be due to 12th change or
depth incision. At loc #2 bed below
are gray clsty + grade into red
clstn below, but just across badlands
st on hill due west small butte at
#2 the cql rests on [red] clstus
with typical Morrison limestone.
This appears here to be a lateral
gradation. Be on lookout for
possible relation between type
of beds in upper Morrison +
nature of overlying Cloucrly SS.
Here thicker SS but not as coarsely
or much cql over gray Morrison
but thin coarse cql over red.
May be local only but at
Theramop, #1+"2 under thick
coarse Cloucrly is black clsty
with plants (yczcl leaves) at
to Morrison. And in Black hills
similar setup locally.
