The Palisades (Hudson River) in the context of "Downstate New York"

North River (Dutch: Noort Rivier) is an alternative name for the southernmost portion of the Hudson River in the vicinity of New York City and northeastern New Jersey in the United States.

Fort Lee is a borough at the eastern border of Bergen County, in the U.S. state of New Jersey, situated along the Hudson River atop The Palisades.

As of the 2020 United States census, the borough's population was 40,191, an increase of 4,846 (+13.7%) from the 2010 census count of 35,345, which in turn reflected a decline of 116 (−0.3%) from the 35,461 counted in the 2000 census. Along with other communities in Bergen County, it is one of the largest and fastest-growing ethnic Korean enclaves outside of Korea.

Andrew Haswell Green (October 6, 1820 – November 13, 1903) was an American lawyer, city planner, and civic leader who was influential in the development of New York City. Green was responsible for Central Park, the New York Public Library, the Bronx Zoo, the American Museum of Natural History, and the Metropolitan Museum of Art. He also participated in or led significant projects, such as Riverside Drive, Morningside Park, Fort Washington Park, and protecting the Hudson River Palisades from destruction. Green is considered "the Father of Greater New York" for his last project to consolidate the city with neighboring towns, chairing the 1897 committee that drew up the plan of amalgamation.

The Palisades Interstate Parkway (PIP) is a 38.25-mile (61.56 km) controlled-access parkway in the U.S. states of New Jersey and New York. The parkway is a major commuter route into New York City from Rockland and Orange counties in New York and Bergen County in New Jersey. The southern terminus of the route is at the George Washington Bridge in Fort Lee, New Jersey, where it connects to Interstate 95 (I-95), US 1-9, and US 46. Its northern terminus is at a traffic circle in Fort Montgomery, New York, where the PIP meets US 9W and US 202 at the Bear Mountain Bridge. At exit 18, the PIP forms a concurrency with US 6 for the remaining duration of its run.

The route is named for the Hudson River Palisades, a line of cliffs rising along the western side of the Hudson River. The PIP is designated, but not signed as Route 445 in New Jersey and New York State Route 987C (NY 987C), an unsigned reference route, in New York. As with most parkways in the New York metropolitan area, commercial traffic is prohibited from using the PIP. The Palisades Interstate Parkway was built from 1947 to 1958, and fully opened to traffic on August 28, 1958.

The Palisades Sill is a Triassic, 200 Ma diabase intrusion. It extends through portions of New York and New Jersey. It is most noteworthy for The Palisades, the cliffs that rise steeply above the western bank of the Hudson River. The ideal location and accessibility of the sill, as well as its unique features, have generated much attention from nature enthusiasts, rock climbers, and geologists alike.

The Palisades Interstate Park Commission (PIPC) was formed in 1900 by Governors Theodore Roosevelt of New York and Foster Voorhees of New Jersey in response to the quarrying operations along the Palisades Cliffs of New Jersey. The Palisades, a National Natural Landmark that are 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. After its formation, the PIPC quickly moved to acquire the lands at the base of the Palisades to stop quarrying operations in both New York and New Jersey. The commission consists of ten commissioners, five appointed by each governor, and was ratified by an Act of Congress in 1937 when its interstate compact was approved. Today, the Commission owns and operates more than 125,000 acres of public parkland in New York and New Jersey including 21 state parks, 8 historic sites, and the Palisades Interstate Parkway. These parks are visited by more than 7 million people annually.
