August 19. Hank's Bay, North-shore continued.
To get the structure and sequence of the north shore into better harmony
with the south shore denton and Edwards revised the forms, Denton's
notes are as follows (They continue three days 160-162):
"On the first part of the first cove west of Horse Island seem heavy
tedded dark fluvial-pay dol. with many small circles of dol. Slip 6 N.
70 W. They strike nearly along shore for about 1/4 mile. Thickness about 75 ft.
[These are of Beekmantown age, but no fossils were seen.]
To the east is an unexploded interval of 300 yards, but the above dol.
forms a bluff on the timbered shore in the first part of this distance
not more than 100 yards. Where line of the faults]
and there it is much fretted. [In a straight line across the strata the distance may be
about 1/3 mile]
The next exposure at a little point over a cove west of the
whole factory is formed by heavy beds of dense fluvial-pay fine grained
diolomitic li. standing in edge. Slip, 75 N. 70 W. This is mostly done about
dol. weathering tuft-geller. Some of these show banding. Thickness exposed
290 ft. [This is undoubtedly the S.O. though not for sure because, the next
fault line in the west of it over the Beekmantown]
This trip is into there. The next exposure is 200 yards across the
cove. Here the cove is fluvial grey dense and fine grained may. li. that
weathering gell-wrink, in layers 3 to 15 moks thick. The beds are nearly all
sin-cracked on the surfaces, and some are riffled. Introp. cogl. is ex-
trémely common. Slip: 8 N. 50 W. These beds gently undulate or that we
first descend through a thickness of 20 feet and then ascend again through
the same to the whole factory, and then descend again at the same
Thickness. From here on the same layers practically forms the crest for
a mile or so to the bottom of the big cove. It undulates gently. The
