Fort Tryon Rocks! Geology Hike

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.

Join our Urban Park Rangers on this hike and learn about why Manhattan rocks!
