description Palisades Escarpment Overview
The Palisades Escarpment is a line of steep cliffs stretching along the western shore of the Hudson River, running roughly 20 miles through parts of New York and New Jersey. The cliffs are composed of Triassic-period igneous rock, specifically diabase formed by magma intrusion, and are noted for their striking columnar jointing visible in the vertical rock faces. Much of the escarpment is preserved within Palisades Interstate Park, a protected area created in the early 1900s through the efforts of conservationists to halt quarrying along the cliffs.

Where is the Palisades Escarpment located?
The Palisades Escarpment runs along the western shore of the Hudson River through parts of New York and New Jersey. The cliff line stretches for roughly 20 miles.
What kind of rock forms the Palisades Escarpment?
The cliffs are mainly made of diabase, an igneous rock formed when magma intruded and cooled during the Triassic Period. That hard rock helps explain why the Palisades form a steep, persistent ridge above the Hudson River.
Can visitors see the Palisades Escarpment from New York City?
The escarpment is visible from parts of the Hudson River corridor and the New York City area, especially from viewpoints facing the New Jersey cliffs. Its position on the river's western shore makes it a major landscape feature north of Manhattan.
Is the Palisades Escarpment a single mountain or a long cliff line?
It is a long line of steep cliffs rather than one isolated mountain peak. The formation follows the Hudson River for about 20 miles across New York and New Jersey.
