What is tri-state monument?

The Tri-State Monument is a historical landmark located at the intersection of Pennsylvania, New York, and New Jersey. It is located in the Delaware Water Gap National Recreation Area and marks the point where the three states converge. The monument was erected in 1884 to settle a land dispute between the states that had been ongoing since the late 1700s. It consists of a simple granite obelisk that stands at 23-feet tall and is surrounded by a small park that is accessible year-round. The monument is a popular destination for tourists and history buffs and serves as a symbol of cooperation between the three states.
