Monday August 8-1910
Corn Head.
Arrived at Corn Head small boat dock at 9.15 A.M. Stepping on shore
at the Post Master's Mr. John Payne, or John Paine.
In the afternoon examined a part of the shore along the north
side of Corn Cove. Here one sees the conglomerate zone No. 15 which
Richardson says has a thickness of 700 feet.
These conglomerates consist of limestone pieces, as a rule sharply
angled from the smallest grain to blocks 15" x 15" x 7" that must weigh
about 100 tons. It is a helter-skelter unassorted mass of light grey
magnesian limestone with all the crevices between the layer pieces
filled in by the deposition, in which it was laid. It is the material
laid down at the base of cliff without any weathering; all the angular
pieces laid down as they fell. When there is a tendency to assorting
of the smaller pieces these are then somewhat rounded. All of the
material seen looks like that I & seen at Ingle Bay but then
maybe material of these the goes up to No. 1, as all of these horizons
have magnesian limestone of a light grey to dark color No. 2. As yet we
have seen no pieces suggesting zones No or the sandstones O.
Every now and then one comes upon zones in the conglomerate series
of lovely bedded stratums like, dense and brittle, easily fracturing,
thin bedded limestone in which are only saw worm burrows
always arranged in pairs. Have a specimen. These beds are
also ripple marked. We also noticed minute faults in these beds
with a throw of 3 to 4 feet pitching outward. Associated with these
limestone also occurs dull flaky scales with very smooth surfaces,
I saw no prints. In other places the bedded limestone have more
less of assorted flats lying pebbles.
