Shale, still with few Fe-quartzite
boulders, pebbly, Loc gray feldarsenica
#7-3.2 from base.
(8) 0,2
Bentonite, loc with hard Fe stained
layers in top of #7 below it.
(9) 14,0
Shale, pebbly, with scattered red
brown weathering to shaly cone
masses, some boulders flattened
frets. A few IS (weather gray quartz)
coves with clinc in upper 3 ft
but most of these start in
base #10 #8=3.8 from base, #9-3.2 from
top.
(10) 25,0:
Shale,(see below). At base first widespread
layer layer first c-in-c and pebbly
red and, locally, septarian is cone
masses - this +/- loc. with
cones protruding into (9) below.
Locally capped by thin bentonite
strata. Above basal cone layer
scattered similar masses without
obvious persistent layers though
may be widespread cones in zones
about 12-15 above base. At top,
seems to be fairly persist,
dominantly septarian cones
quartz wrapping, moderate (1/2/dirty)
