Of sandstone I see but one block and of actual shale and
lignites none. All of the limestones may have been derived
from a single limestone formation, from the other points.
Towards the top the layer blocks disappear and at the top the
2 to 3 feet thick
of cross bedded limestone is made of 9 ounce
puffs, showing stratification and over an trilobation.
Beneath block shale gone there is a good long light green
(purty yellow) laminated hard shales about 5 feet thick. At the base
of it then in an 8 inch zone of limestone conglomerate in which
the puffs are all flat, many more 1 inch thick and 6 inches by.
The li. are again of marine sorts, and here there is also considerable
block shale. All are marine forms as the white was laid down
in waters with motion. Otherwise I see no conglomerate nearby.
This lower limestone vanishes out in a distance of 20 feet up its
cliff.
On the north south strike at the east end of Main street
the lower conglomerate is about 3 feet thick. It is an odd bed of a fine
grasty coarse sand in which are mingled small li. puffs, and larger
puffs.
Flat Rock (hard) shales are black shale. The Hard Flat puffs are
