The sand which makes up the "sandstone" found in "New York" state was originally deposited in "horizontal layers".
Explanation:
The sandstones found in New York were majorly formed due to the deposition of sand by the water.
This deposition was obviously horizontal. The sand particles got glued together gradually because of the presence of traces of calcium carbonate, clay and silica.
The sandstone rocks found in "northern New York" are from the Ordovician age.
