"Following the line for a distance of about 2 1/2 miles to the north and northeast, one passes through ~ great thicknesses of freemill, red
and Haclish shale with thin shreds of sandstone, all steeply dipping
edges and cut across by the same. These beds only dip about 60° E.
There must be a fault here for the succeeding bed dips N. 5° W., and
they form a continuous section of 1357 feet in thickness to the base
of the Long Point Series [In the present all of these strata must be added
to the Parsons series]
"The sequence as measured in detail from the base up is as follows:
200 feet. Dark gray to black sandy shale and thin layers of sandstone,
dip near N 60° W, 50° E.
200 feet. Freemill clay, even grained sandstone at base but becoming coarser at
15 feet up and passing into conglomerate with the pebbles mostly the
size of peas and consisting of quartz, red feldspar, Haclish chert, dark
shale etc. Among these are many scattered pebbles of later age which
are angular, many of the latter of local material. They are often 6 with
a or acorns. These beds become very massive in the upper half.
Many round cannon ball-like concretions from 3 to 8 inches in
diameter occur. The upper half of the beds consist of an alternation
of bands or lenses of conglomerate and free grained sandstone.
The upper beds are much jointed and fractured. Smaller a small headland,
Fault
100 feet. Grey fine and even grained Haclish freemill shale, weathering
dark red. Dip 45° N, 25° E.
