Tri-States Monument - aka Tri-State Rock - Port Jervis, NY
Stand on the Tri-State Rock and be in three different States!
This Monument was placed in 1882, and serves as the northern end of New Jersey's boundary with Pennsylvania, and the northwest end of the New York/ New Jersey boundary line- where the Neversink and Delaware Rivers converge. It sits at waters edge at the southwestern edge of a peninsula. The 3 lines cut designate the state boundaries of NY, NJ, and PA.
In truth, the actual corner between NY & PA is in the middle of the Delaware River - about 475 feet due west of the Tri-State Rock. The nearby Witness Monument, located under the overpass, relates that information.
A U.S. Coast and Geodetic survey disk used to sit atop, and that benchmark was stamped LAUREL No. 2 1942.
It is at a location historically known as Carpenter's Point, near the current Interstate 84 overpass. This site is accessed via the road located within Laurel Grove Cemetery in Port Jervis, NY.
One can see the monument from a parking area located below the Interstate 84 overpass. To access the monument, one must be able to traverse an uneven rocky and sandy area.
Also accessible by canoe.
