The Palisades of New Jersey were formed as a result of the breakup of supercontinent Pangaea, beginning roughly 200 million years ago. They were underground lava/magma flows that rose up from below as the northeast coast began to fracture. It was the birth of the Atlantic Ocean.

You can find Palisades boulders throughout New York City, many in plain view in Central Park. They were carried there by the glaciers during the last ice age, 200 or so million years after they were formed.
