Steep cliffs along the west side of the lower Hudson River

The Palisades, also called the New Jersey Palisades or the Hudson River Palisades, are a line of steep cliffs along the west side of the lower Hudson River in Northeastern New Jersey and Southeastern New York in the United States. The cliffs stretch north from Jersey City about 20 miles (32 km) to near Nyack, New York, and are visible at Haverstraw, New York. They rise nearly vertically from near the edge of the river, and are about 300 feet (91 m) high at Weehawken, increasing gradually to 540 feet (165 m) high near their northern terminus. North of Fort Lee, the Palisades are part of Palisades Interstate Park and are a National Natural Landmark. The Palisades are among the most dramatic geologic features in the vicinity of New York City, forming a canyon of the Hudson north of the George Washington Bridge, as well as providing a vista of the Manhattan skyline. They sit in the Newark Basin, a rift basin located mostly in New Jersey. Palisade is derived from the same root as the word pole, ultimately from the Latin word palus, meaning stake. A "palisade" is, in general, a defensive fence or wall made up of wooden stakes or tree trunks. The Lenape called the cliffs "rocks that look like rows of trees", a phrase that became "Weehawken", the name of a town in New Jersey that sits at the top of the cliffs across from Midtown Manhattan.

The basalt cliffs are the margin of a diabase sill, formed about 200 million years ago, at the close of the Triassic period by the intrusion of molten magma upward into sandstone. The molten material cooled and solidified before reaching the surface. Water erosion of the softer sandstone left behind the columnar structure of harder rock that exists today. The cliffs are about 300 ft (100 m) thick in sections and originally may have reached 1,000 ft (300 m). The end Triassic extinction event that coincided with the formation of the Hudson Palisades, Central Atlantic magmatic province, 200 million years ago ranks second in severity of the five major extinction episodes that span geologic time. The most severe extinction in the past 500 million years was the Permian–Triassic extinction event, informally known as the Great Dying, coincided with flood basalt eruptions that produced the Siberian Traps, which constituted one of the largest known volcanic events on Earth and covered over 770,000 sq mi (2,000,000 km2) with lava

Franklyn Van Houten completed groundbreaking research on a rock formation known as the Newark Basin. His discovery of a consistent geological pattern in which lake levels rose and fell is now known as the "Van Houten cycle".
