Moss Island, National Natural Landmark in Little Falls, New York.
Moss Island spans 1500 feet in length and 625 feet in width, featuring deep geological formations called potholes between the Mohawk River and Barge Canal.
The construction of canal locks in 1793 transformed this land mass into an island, allowing boats to navigate around the 40-foot falls in the Mohawk River.
Rock climbing enthusiasts gather at the island's metasyenite cliffs, which contain over 100 established routes ranging from beginner to advanced difficulty levels.
The location provides free parking facilities and includes a walkway next to the guillotine gate that enables visitors to cross the canal system.
The southern cliff reaches 45 feet in height and contains numerous circular rock formations, with potholes extending 40 to 50 feet deep into the surface.
