almost devoid of bedding
The sandstones are dark greenish in color
are coarse of grain and while most is a fine
conglomerate, the parcel beds with the pebbles up
to 1/2 inch, though some coming around 1/4 inch,
are in more or less widely separated grains. These
pebble beds lie usually in thin sheets though at
Times (towards the bottom) the whole grain is more or
sandstones
less conglomeratic. The pebbles are of fairly well
rounded white (dominant) and pink vein quartz
with scattering ones of pink feldspars. In
places slate pebbles are common in green
sandy slate in pieces up to 4 or 5 inches across and
up to 1 1/2 inches thick. There are also small pieces
of black shale. This shows considerable streaming
action and yet there is almost no cross bedding.
Only in places at the top of a thin bed is there a
grain about 6 ft's wide, thick that is decidedly
cross bedded and then are we away to the P.E.
Evidences of foresetting type.
The dip of the sandstones is about 30 deg to 45 deg.
