Urban Park Rangers: Fort Tryon Rocks!

New York City is the site of ancient earth-shaking and earth-shaping events. The bedrock that anchors the city’s skyscrapers tells a story of a place going back more than a billion years. The island of Manhattan is built on three strata known as Manhattan Schist, Inwood Marble, and Fordham Gneiss. Meet the Rangers at Fort Tryon Park’s Broadway and Arden Street entrance.
