Here is some chalk at the top, rather chalk due to weathering.
Then comes in the Lower Bendel. First a sandy
Dolomite (du pierre) about 3 feet thick. The basal 3 to 8
inches is muddy and without chalk, and the rest is about
50% made up of chalk jetties face signs derived from
the Ellenstrump. It's a complement with the pettles
of chalk. Mr Smith's gang kind.
Then a blue-grey nodular clay li, about 18 inch
thick. I thought this bed also to be some erratic,
but on the ground side on the higher lane
Then a blue clay or soft shale with dark nodules
and then goes of immense dark li, in after far. All
smells of petroleum. Thickness here about 40 feet.
Fossils are accordingly scarce in the nodules and hard
any in the clay. The commoner ones are Leptaptychus,
Lingula 2 or 3 species, Osticuloides, Ambroclin
plansemmous (1 specimen), and ostracoda. In this
clay layer times pieces of rather large goniatites
are frequent and finally I succeeded in getting two
species that can be identified.
Once this shale follows the Marble Falls li. But later
I learn that those blue dense earth li in Glen Falls absolutely to the
Lower Bendel strata. The three Ambroclinian top type.
Then continued S.E. to about 7 miles from San Veta
where on the road side may be seen great exposure of
the top of the Marble Falls li dipping steeply about 70 degrees.
