Manhattan Schist

:

Manhattan Schist is the rock that underlies much of the island. Because of this unique geographic condition, NYC is ideally suited for skyscrapers, which are found in parts of the city where the schist is close to the surface.

In Central Park, a huge, notable schist formation is Rat Rock.
