July 16 - Tuesday. Middle Point.
Rained hard last night and this morning there is a raining fog. By
10 A.M., it has cleared enough to start on our journey. Our boat takes us
across to the middle of the western side of Middle Point but we see no
rocks. We remain in the boat until within a mile of the northern extremity
and then proceed on Middle Point (= Middle Peninsula). On shore, there is a
[illegible]
crushed series of thinly bedded sandstone separated by thin zones of shale all of
which are to be seen.
[illegible]
of greenish or light blue clay. Towards the joint orthogon of the strata are to
be seen on either shore. On the eastern side about 1 mile from the point
[illegible]
spindles of a lime slate with Richardsonian prints like those found at Clear
Banks Cove. Other loose pieces were seen along the shore in the next half
mile southward. Kept the first slate formed on hand here. These data are
[illegible]
by boat
[illegible]
We then proceed about two miles more south-eastward and south
south-half of the long
shores. Here we are in the consolidated shale series seen in the north part of
mine of the Richardsonian sandstone and conglomerate are present. The upper part of the section resembles that found at
East Bay. Here, we continue to within 1/2 mile of the Dominion Dam and
[illegible]
Shale Coquimbo.
Here they are unconformably overlain by the Brinkon
series. [illegible] All of these shales are named by Hardy as Brinkon
series. The genus has a green one foot thick of bi calycomate and the small perforate shell animal.
The Brinkon lies nearly horizontal but is undulatory due to deformation.
It begins with a braided bed 6 to 10 feet thick. The borders are
subangular and a size up to nearly 2 feet across. They appear to be all of the
white and black fine grained sandstone and dolomite of the Bedlamation.
Above lie thinly bedded shale, sandstone and shales, some sandstones and four
conglomerates. A peculiar feature of the chosen beds are their contorted and
even folded nature due to slippage while the ones were still soft.
[illegible]
above and between the beds are granular stratified. See the photos.
On these lower beds I saw a few small [illegible] and a rare
