Hudson River

The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York in the United States. The river originates in the Adirondack Mountains of Upstate New York, flows through the Hudson Valley, and eventually drains into the Atlantic Ocean, between New York City and Jersey City. The river serves as a political boundary between the states of New Jersey and New York, and further north between New York counties. The lower half of the river is a tidal estuary occupying the Hudson Fjord, which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Tidal waters influence the Hudson's flow from as far north as Troy.

The river is named after Henry Hudson, an Englishman sailing for the Dutch East India Company, who explored it in 1609, and after whom Canada's Hudson Bay is also named. It had previously been observed by Italian explorer Giovanni da Verrazano sailing for King Francis I of France in 1524, as he became the first European known to have entered the Upper New York Bay, but he considered the river to be an estuary. The Dutch called the river the North River – with the Delaware River called the South River – and it formed the spine of the Dutch colony of New Netherland. Settlement of the colony clustered around the Hudson, and its strategic importance as the gateway to the American interior led to years of competition between the English and the Dutch over control of the river and colony.

New Jersey

New Jersey is a state in the Northeastern and Middle Atlantic regions of the United States. It is bordered on the north and east by New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, and on the southwest by Delaware. New Jersey is the fourth-smallest state, but the 11th-most populous and the most densely populated of the 50 United States. New Jersey lies entirely within the combined statistical areas of New York City and Philadelphia and is the second-wealthiest U.S. state by median household income as of 2014.

New Jersey was inhabited by Native Americans for more than 2,800 years, with historical tribes such as the Lenape along the coast. In the early 17th century, the Dutch and the Swedes made the first European settlements. The English later seized control of the region, naming it the Province of New Jersey after the largest of the Channel Islands, Jersey, and granting it as a colony to Sir George Carteret and John Berkeley, 1st Baron Berkeley of Stratton. New Jersey was the site of several decisive battles during the American Revolutionary War in the 18th century.

New York

New York is a state in the Northeastern United States and is the United States' 27th-most extensive, fourth-most populous, and seventh-most densely populated state. New York is bordered by New Jersey and Pennsylvania to the south and Connecticut, Massachusetts, and Vermont to the east. The state has a maritime border in the Atlantic Ocean with Rhode Island, east of Long Island, as well as an international border with the Canadian provinces of Quebec to the north and Ontario to the west and north. The state of New York, with an estimated 19.8 million residents in 2015, is often referred to as New York State to distinguish it from New York City, the state's most populous city and its economic hub.

With an estimated population of nearly 8.5 million in 2014, New York City is the most populous city in the United States and the premier gateway for legal immigration to the United States. The New York City Metropolitan Area is one of the most populous urban agglomerations in the world. New York City is a global city, exerting a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term New York minute. The home of the United Nations Headquarters, New York City is an important center for international diplomacy and has been described as the cultural and financial capital of the world, as well as the world's most economically powerful city. New York City makes up over 40% of the population of New York State. Two-thirds of the state's population lives in the New York City Metropolitan Area, and nearly 40% live on Long Island. Both the state and New York City were named for the 17th century Duke of York, future King James II of England. The next four most populous cities in the state are Buffalo, Rochester, Yonkers, and Syracuse, while the state capital is Albany.

The Palisades (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 southern New York in the United States. The cliffs stretch north from Jersey City approximately 20 mi (32 km) to near Nyack, New York. They rise nearly vertically from near the edge of the river, and are approximately 300 feet high at Weehawken and increasing gradually to 540 feet high near their northern terminus. From Fort Lee north 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 George Washington Bridge, as well as providing a vista of the skyline. They are located in the Newark Basin, a rift basin located mostly in New Jersey.

Palisade is derived from the same root as word pale, 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 Manhattan.

New York City

New York—often called New York City or the City of New York to distinguish it from the State of New York, of which it is a part—is the most populous city in the United States and the center of the New York metropolitan area, the premier gateway for legal immigration to the United States and one of the most populous urban agglomerations in the world. A global power city, New York exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.

Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of which is a separate county of New York State. The five boroughs – Brooklyn, Queens, Manhattan, the Bronx, and Staten Island – were consolidated into a single city in 1898. With a census-estimated 2014 population of 8,491,079 distributed over a land area of just 305 square miles (790 km²), New York is the most densely populated major city in the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. By 2014 census estimates, the New York City metropolitan region remains by a significant margin the most populous in the United States, as defined by both the Metropolitan Statistical Area (20.1 million residents) and the Combined Statistical Area (23.6 million residents). In 2013, the MSA produced a gross metropolitan product (GMP) of nearly US$1.39 trillion, while in 2012, the CSA generated a GMP of over US$1.55 trillion, both ranking first nationally by a wide margin and behind the GDP of only twelve and eleven countries, respectively.
