On Rifle Camp Road, just off of Route 46, is a historic marker that reads: "Great Notch - Used by Washington as a lookout while quartered at the Dey House, October 1780. Major Parr's Rifle Corps camped in ravine " [1]
Up the road from the historic street marker is Rifle Camp park, named for Major Parr's Rifle Corps that camped here. Go to the top of the hill in the park to see the fantastic view of New York. This was used as a lookout by Washington's troops.
The sign reads:
"Washington's Lookout ~ Great Notch ~ On October 23, 1780, the light infantry was stationed here. The hill on the east side of the Notch was used by Washington as a lookout from which to observe the movement of his troops. " [2]
