disturbed but in general the dip is about vertical. As I pro-
ced along these low cliffs, I see nearly 800 feet or more of
brick red shales, sometimes all standing vertical,

in the next southward going 1/3 mile nothing is seen up
to the roof. Partially the brick red shales of cliv.8 are in view.
On the north side of the roof considerable gypsum sticks
out resting on brick red shales. The dip and strike are
totally different. The dip is steeply to the southeast at least 45°
The gypsum is therefore the lower beds seen of the Winton
on the north side of the roof
series. Over it follows brick red shales with gnomes of
exposure nodular limestone that have red shales snuffed
around the modules.

Bill tells me that it is in this
limestone that he saw at lowy tide the Winton nautili,
and tirelores. These are the lowest strata to be seen on
this side of the peninsula. Over them lie a very great
tickness (perhaps 3/4 of a mile across the strike of strata)
