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.
