Tri-States Monument
The Tri-States Monument (also known as Tri-State Rock) is a granite monument that marks the tripoint of the state boundaries of New Jersey, New York, and Pennsylvania. It is at the northwestern end of the boundary between New Jersey and New York, the northern end of the boundary between New Jersey and Pennsylvania, and the eastern end of the boundary between New York and Pennsylvania. The monument is located at the confluence of the Delaware and Neversink rivers. This location is also known as Carpenter's Point.The nearby Witness Monument, also known as the Reference Monument or the western State Line Monument, is a taller upright granite monument located south of the Laurel Grove Cemetery in Port Jervis, New York, and under a bridge for Interstate 84. It is not directly on any state boundary, but instead witnesses the location of two points: this tripoint and the corner boundary point between New York and Pennsylvania in the Delaware River.The Supreme Court of the United States summarized the boundaries of these three states with respect to this monument in New Jersey v. New York, 283 U.S. 336 (1931): ... where it (the Delaware) forms a boundary between New York and Pennsylvania. The Delaware continues its course as such boundary to Tristate Rock, near Port Jervis in New York, at which point Pennsylvania and New York are met by New Jersey. From there the river marks the boundary between Pennsylvania and New Jersey until Pennsylvania stops at the Delaware state line, and from then on the river divides Delaware from New Jersey until it reaches the Atlantic between Cape Henlopen and Cape May. Also, it is the northernmost point of New Jersey, in Montague Township, Sussex County.
