Palisades

Palisades, cliffs, on the western bank of the Hudson River, in southeastern New York and northeastern New Jersey. The cliffs rise from near the river's edge to elevations ranging from about 90 to 170 m (about 300 to 550 ft). They extend north about 32 km (about 20 mi) from Jersey City, New Jersey, to Piermont, New York. The Palisades were formed by the slow cooling of molten rock at the end of the Triassic period (some 195 million years ago). Much of the region is included in the Palisades Interstate Park, a series of recreation areas on the western bank of the river.
