"August 10, continued
Faith E., at about beneath the Pic occurs a crane
sometime of considerable thickness. See [illegible]. These SS strike N. 30 W. and dip from 45° to 60° S. and somewhat. All
of them constitute what I call an arc rising to Peruano.
He decided for awhile at the Three Sisters, where the beds are as usual very critical and troubling in dip and
strike. I assume it is more [illegible] up to the cliffs gone
at the north end of Cape Barre.
The irregularity in deformation all along the Buraille
saves me the impression that the structure is a closed syncline
in more or less incompetent beds. Or this is an overthrust
favour given here cutting out many folds just to Peruano Barre.
Once around Cape Barre at low tide one can walk
[illegible]
all along this coast, but there is no way to getting here except by
our boat, or coming from the north by walking.
It will take many days to travel and surround the structure
and determine the delimitations of the formations.
The above interpretation is very different from Clarke's
interpretation. I did not at once see the anticline under
the Pic as he has it and the syncline to the north. Those
structures as he has it are transverse to the actual structure
which appears like a faulted or thrustled broken syncline
or anticline. Which he cannot make out as yet.
The whole Pic d'Amore is either parallel to Peruano ls, but
as Clarke says,
of they underlie them, then there must be a fault between Peruano
Rock and Ant. Joli and the Coûte to the south of the Three Sisters.
I am disposed to regard them as younger than the Peruano ls.
