Left Pat Jervis at 7:40 pm Ottisville to walk
back to P.J. and to go at 3:26 p.m. to Delaware
train Stop.
The Hudson River is here a laminated shale
and not at all a sandstone as at Kingston. The
angle of dip is also much steeper thus the dip
here must be about 50 or even 55 degrees.
The plane with the Haverstraw is leveled
initially 10 degrees so that the dip of the conglomerate
is about 45 degrees. At Kingston the plane was much greater
The bas at seven feet of the Haverstraw is a
course grain quartz conglomerate with the average of
the pebbles between 3/4 and 1 1/4 inches. They are only
subrounded and these pebbles rest directly on the shale
without transition. The pebbles gradually become
less large than every now and then some of larger
ones appear. There is also cross bedding throughout
though not pronounced. The beds range from 6 inches
to about 2 feet thus the average would be 8 to
12 inches. Occasionally one sees thin zones of
