Manhattan Prong, Geological formation beneath Manhattan and Bronx, US.
The Manhattan Prong contains three primary rock types: Manhattan Schist, Inwood Marble, and Fordham Gneiss, extending through New York City's bedrock foundation.
The formation dates back over one billion years, shaped during the Grenville Orogeny when ancient mountains formed through continental collisions.
Local universities conduct regular field studies in Central Park and Inwood Hill Park to examine rock formations and teach students about regional geology.
Visitors can observe exposed rock formations at multiple locations, including Central Park, Wave Hill, and Pelham Bay Park throughout the year.
The bedrock structure supports Manhattan's numerous skyscrapers, with the schist's strength allowing construction of some of the world's tallest buildings.
