191-717: The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York , United States. It originates in the Adirondack Mountains of upstate New York at Henderson Lake in the town of Newcomb , and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City , eventually draining into the Atlantic Ocean at Upper New York Bay . The river serves as
382-582: A lake , an ocean , or another river. A stream refers to water that flows in a natural channel , a geographic feature that can contain flowing water. A stream may also be referred to as a watercourse. The study of the movement of water as it occurs on Earth is called hydrology , and their effect on the landscape is covered by geomorphology . Rivers are part of the water cycle , the continuous processes by which water moves about Earth. This means that all water that flows in rivers must ultimately come from precipitation . The sides of rivers have land that
573-743: A tribal jurisdictional area in Caddo County, Oklahoma , that they share with the Caddo Nation and Wichita and Affiliated Tribes . The Unami and Munsee languages belong to the Eastern Algonquian language group and are largely mutually intelligible . Moravian missionary John Heckewelder wrote that Munsee and Unami "came out of one parent language." Only a few Delaware First Nation elders in Moraviantown, Ontario , fluently speak Munsee. William Penn , who first met

If the ball was picked up by a woman, she could not be tackled by the men, although men could attempt to dislodge the ball. Women were free to tackle the men. Another common activity was that of dance, and yet again, gender differences appear: men would dance and leap loudly, often with bear claw accessories, while women, wearing little thimbles or bells, would dance more modestly, stepping "one foot after
1146-740: A boat along certain stretches. In these religions, such as that of the Altai in Russia , the river is considered a living being that must be afforded respect. Rivers are some of the most sacred places in Hinduism. There is archeological evidence that mass ritual bathing in rivers at least 5,000 years ago in the Indus river valley . While most rivers in India are revered, the Ganges is most sacred. The river has

Hindus believe that when the cremated remains of a person is released into the Ganges, their soul is released from the mortal world. Freshwater fish make up 40% of the world's fish species, but 20% of these species are known to have gone extinct in recent years. Human uses of rivers make these species especially vulnerable. Dams and other engineered changes to rivers can block
1528-408: A continuous flow of water throughout the year. This may be because an arid climate is too dry depending on the season to support a stream, or because a river is seasonally frozen in the winter (such as in an area with substantial permafrost ), or in the headwaters of rivers in mountains, where snowmelt is required to fuel the river. These rivers can appear in a variety of climates, and still provide

One of the more common activities of leisure for the Lenni Lenape would be the game of pahsaheman : a football-like hybrid, split on gender lines. Over a hundred players were grouped into gendered teams (male and female) to try getting
1910-786: A divided people during the 1770s, including in Killbuck's family. Killbuck resented his grandfather for allowing the Moravians to remain in the Ohio country. The Moravians believed in pacifism, and Killbuck believed that every convert to the Moravians deprived the Lenape of a warrior to stop further white settlement of their land. In the beginning of the American Revolutionary War , Killbuck and many Lenape claimed to be neutral. Other neighboring Indian communities, particularly
2101-513: A garrison at Bergen , which allowed settlement west of the Hudson within the province of New Netherland . This land was purchased from the Lenape after the fact. New Amsterdam was founded in 1624 by the Dutch in what would later become New York City . Dutch settlers also founded a colony at present-day Lewes, Delaware , on June 3, 1631, and named it Zwaanendael (Swan Valley). The colony had

This can happen in karst systems, where rock dissolves to form caves. These rivers provide a habitat for diverse microorganisms and have become an important target of study by microbiologists . Other rivers and streams have been covered over or converted to run in tunnels due to human development. These rivers do not typically host any life, and are often used only for stormwater or flood control. One such example
2483-403: A large depositional plain near its mouth. This lack of significant deposits near the river mouth differs from most other American estuaries. Around New York Harbor, sediment also flows into the estuary from the ocean when the current is flowing north. The area around Hudson River was inhabited by indigenous peoples ages before Europeans arrived. The Lenape , Wappinger , and Mahican branches of

This has been attributed to unusually large floods destroying infrastructure; however, there is evidence that permanent changes to climate causing higher aridity and lower river flow may have been the determining factor in what river civilizations succeeded or dissolved. Water wheels began to be used at least 2,000 years ago to harness the energy of rivers. Water wheels turn an axle that can supply rotational energy to move water into aqueducts , work metal using
2865-518: A lower elevation , such as an ocean , lake , or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle , the processes by which water moves around the Earth. Water first enters rivers through precipitation , whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow , or seepage from aquifers beneath
3056-539: A man's maternal uncle (his mother's brother), and not his father, was usually considered to be his closest male relative, since his uncle belonged to his mother's clan and his father belonged to a different one. The maternal uncle played a more prominent role in the lives of his sister's children than did the father—for example likely being the one responsible for educating a young man in weapons craft, martial arts, hunting, and other life skills. Lenape practiced companion planting , in which women cultivated many varieties of
3247-556: A peak in the 1970s, when between two or three dams were completed every day, and has since begun to decline. New dam projects are primarily focused in China , India , and other areas in Asia . The first civilizations of Earth were born on floodplains between 5,500 and 3,500 years ago. The freshwater, fertile soil, and transportation provided by rivers helped create the conditions for complex societies to emerge. Three such civilizations were

The lower half of the river is a tidal estuary , deeper than the body of water into which it flows, occupying the Hudson Fjord , an inlet that formed during the most recent period of North American glaciation , estimated at 26,000 to 13,300 years ago. Even as far north as
3629-891: A ritualistic sense has been compared to the Christian ritual of baptism , famously the Baptism of Jesus in the Jordan River . Floods also appear in Norse mythology , where the world is said to emerge from a void that eleven rivers flowed into. Aboriginal Australian religion and Mesoamerican mythology also have stories of floods, some of which contain no survivors, unlike the Abrahamic flood. Along with mythological rivers, religions have also cared for specific rivers as sacred rivers. The Ancient Celtic religion saw rivers as goddesses. The Nile had many gods attached to it. The tears of
3820-425: A river can take several forms. Tidal rivers (often part of an estuary ) have their levels rise and fall with the tide . Since the levels of these rivers are often already at or near sea level, the flow of alluvium and the brackish water that flows in these rivers may be either upriver or downriver depending on the time of day. Rivers that are not tidal may form deltas that continuously deposit alluvium into
4011-756: A river such as fish , aquatic plants , and insects have different roles, including processing organic matter and predation . Rivers have produced abundant resources for humans, including food , transportation , drinking water , and recreation. Humans have engineered rivers to prevent flooding, irrigate crops, perform work with water wheels , and produce hydroelectricity from dams. People associate rivers with life and fertility and have strong religious, political, social, and mythological attachments to them. Rivers and river ecosystems are threatened by water pollution , climate change , and human activity. The construction of dams, canals , levees , and other engineered structures has eliminated habitats, has caused

Hydroelectricity is desirable as a form of renewable energy that does not require any inputs beyond the river itself. Dams are very common worldwide, with at least 75,000 higher than 6 feet (1.8 m) in the U.S. Globally, reservoirs created by dams cover 193,500 square miles (501,000 km ). Dam-building reached
4393-410: A short life, as in 1632 a local band of Lenape killed the 32 Dutch settlers after a misunderstanding escalated over Lenape defacement of the insignia of the governing Dutch West India Company . The Lenape's quick adoption of trade goods, and their desire to trap furs to meet high European demand, resulted in over-harvesting the beaver population in the lower Hudson Valley. With the fur sources exhausted,
4584-491: A small "round crest, of about 2 inches in diameter". Deer hair, dyed a deep scarlet, as well as plumes of feathers, were favorite components of headdresses and breast ornaments for males. The Lenape also adorned themselves with various ornaments made of stone, shell, animal teeth, and claws. The women often wore headbands of dyed deer hair or wampum. They painted their skin skirts or decorated them with porcupine quills. These skirts were so elaborately appointed that, when seen from

The Delaware of Six Nations shares the Glebe Farm 40B in Brantford, Ontario , and Six Nations Indian Reserve No. 40 , shared with six Haudenosaunee peoples in Ontario. The Stockbridge-Munsee Community has a 22,139-acre (89.59 km ) Indian reservation in Wisconsin, with 16,255 acres (65.78 km ) held in federal trust. The Delaware Nation has
4966-438: A water body is that body's riparian zone . Plants in the riparian zone of a river help stabilize its banks to prevent erosion and filter alluvium deposited by the river on the shore, including processing the nitrogen and other nutrients it contains. Forests in a riparian zone also provide important animal habitats . River ecosystems have also been categorized based on the variety of aquatic life they can sustain, also known as
5157-645: A water cycle that involved precipitation. The term flumen , in planetary geology , refers to channels on Saturn 's moon Titan that may carry liquid. Titan's rivers flow with liquid methane and ethane . There are river valleys that exhibit wave erosion , seas, and oceans. Scientists hope to study these systems to see how coasts erode without the influence of human activity, something that isn't possible when studying terrestrial rivers. Lenape The Lenape ( English: / l ə ˈ n ɑː p i / , /- p eɪ / , / ˈ l ɛ n ə p i / ; Lenape languages : [lənaːpe] ), also called

As in the case of the Iroquois and Susquehannocks , the animosity of differences and competitions spanned many generations, and in general tribes with each of the different language groups became traditional enemies in the areas they'd meet. On the other hand, The New American Book of Indians points out that competition, trade, and wary relations were far more common than outright warfare—but both larger societies had traditions of 'proving' (blooding) new (or young) warriors by ' counting coup ' on raids into another tribes territories. The two groups were sometimes bitter enemies since before recorded history, but intermarriage occurred — and both groups have an oral history suggesting they jointly came east together and displaced
5539-537: Is 315 miles (507 km) long, with depths of 30 feet (9.1 m) for the stretch south of the Federal Dam, dredged to maintain the river as a shipping route. Some sections there are around 160 feet deep, and the deepest part of the Hudson, known as "World's End" (between the US Military Academy and Constitution Island ) has a depth of 202 feet (62 m). The Hudson and its tributaries, notably
5730-445: Is a tributary , and the place they meet is a confluence . Rivers must flow to lower altitudes due to gravity . The bed of a river is typically within a river valley between hills or mountains . Rivers flowing through an impermeable section of land such as rocks will erode the slopes on the sides of the river. When a river carves a plateau or a similar high-elevation area, a canyon can form, with cliffs on either side of
5921-504: Is also important for the lumber industry , as logs can be shipped via river. Countries with dense forests and networks of rivers like Sweden have historically benefited the most from this method of trade. The rise of highways and the automobile has made this practice less common. One of the first large canals was the Canal du Midi , connecting rivers within France to create a path from

6112-564: Is an ancient dam built on the Nile 4,500 years ago. The Ancient Roman civilization used aqueducts to transport water to urban areas . Spanish Muslims used mills and water wheels beginning in the seventh century. Between 130 and 1492, larger dams were built in Japan, Afghanistan, and India, including 20 dams higher than 15 metres (49 ft). Canals began to be cut in Egypt as early as 3000 BC, and
6303-448: Is at a higher elevation than the river itself, and in these areas, water flows downhill into the river. The headwaters of a river are the smaller streams that feed a river, and make up the river's source. These streams may be small and flow rapidly down the sides of mountains . All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. A ridge of higher elevation land
6494-405: Is because any natural impediment to the flow of the river may cause the current to deflect in a different direction. When this happens, the alluvium carried by the river can build up against this impediment, redirecting the course of the river. The flow is then directed against the opposite bank of the river, which will erode into a more concave shape to accommodate the flow. The bank will still block
6685-528: Is believed that the first use of the name Hudson River in a map was in a map created by the cartographer John Carwitham in 1740. In 1939, the magazine Life described the river as "America's Rhine", comparing it to the 760-mile (1,220 km) Rhine in Central and Western Europe. The tidal Hudson is unusually straight for a river, and the earliest colonial Dutch charts of the Hudson River designated

Along the river, the Palisades are of metamorphic basalt , or diabases , the Highlands are primarily granite and gneiss with intrusions , and from Beacon to Albany, shales and limestones , or mainly sedimentary rock . The Narrows were most likely formed about 6,000 years ago at the end of the last ice age. Previously, Staten Island and Long Island were connected, preventing
7449-497: Is in part because of a projected loss of snowpack in mountains, meaning that melting snow can't replenish rivers during warm summer months, leading to lower water levels. Lower-level rivers also have warmer temperatures, threatening species like salmon that prefer colder upstream temperatures. Attempts have been made to regulate the exploitation of rivers to preserve their ecological functions. Many wetland areas have become protected from development. Water restrictions can prevent

The river was then used for shipping crops from the American Midwest and cotton from the American South to other states as well as the Atlantic Ocean. The role of urban rivers has evolved from when they were a center of trade, food, and transportation to modern times when these uses are less necessary. Rivers remain central to
8213-553: Is the Sunswick Creek in New York City, which was covered in the 1800s and now exists only as a sewer-like pipe. While rivers may flow into lakes or man-made features such as reservoirs , the water they contain will always tend to flow down toward the ocean . However, if human activity siphons too much water away from a river for other uses, the riverbed may run dry before reaching the sea. The outlets mouth of

One example of this is the Continental Divide of the Americas in the Rocky Mountains . Water on the western side of the divide flows into the Pacific Ocean , whereas water on the other side flows into the Atlantic Ocean . Not all precipitation flows directly into rivers; some water seeps into underground aquifers . These, in turn, can still feed rivers via

Another example is the restoration of the Isar in Munich from being a fully canalized channel with hard embankments to being wider with naturally sloped banks and vegetation. This has improved wildlife habitat in the Isar, and provided more opportunities for recreation in the river. As a natural barrier , rivers are often used as a border between countries , cities, and other territories . For example,

The restoration of water quality and recreation to urban rivers has been a goal of modern administrations. For example, swimming was banned in the Seine for over 100 years due to concerns about pollution and the spread of E. coli , until cleanup efforts to allow its use in
14325-484: The discharge of a river, the amount of water passing through it at a particular time. The flow of a river can act as a means of transportation for plant and animal species, as well as a barrier. For example, the Amazon River is so wide in parts that the variety of species on either side of its basin are distinct. Some fish may swim upstream to spawn as part of a seasonal migration . Species that travel from
14516-465: The extinction of some species, and lowered the amount of alluvium flowing through rivers. Decreased snowfall from climate change has resulted in less water available for rivers during the summer. Regulation of pollution, dam removal , and sewage treatment have helped to improve water quality and restore river habitats. A river is a natural flow of freshwater that flows on or through land towards another body of water downhill. This flow can be into
14707-436: The mound builders culture. In addition, both tribes practiced adopting young captives from warfare into their tribes and assimilating them as full tribal members. Iroquoians adopting Lenape (or other peoples) were known to be part of their religious beliefs, the adopted one taking the place in the clan of one killed in warfare. Early European observers may have misinterpreted matrilineal Lenape cultural practices. For example,
14898-436: The sea . The sediment yield of a river is the quantity of sand per unit area within a watershed that is removed over a period of time. The monitoring of the sediment yield of a river is important for ecologists to understand the health of its ecosystems, the rate of erosion of the river's environment, and the effects of human activity. Rivers rarely run in a straight direction, instead preferring to bend or meander . This
15089-521: The water table , the groundwater beneath the surface of the land stored in the soil . Water flows into rivers in places where the river's elevation is lower than that of the water table. This phenomenon is why rivers can still flow even during times of drought . Rivers are also fed by the melting of snow glaciers present in higher elevation regions. In summer months, higher temperatures melt snow and ice, causing additional water to flow into rivers. Glacier melt can supplement snow melt in times like
15280-787: The 1800s. One of the most significant canals of this era was the Erie Canal . The canal was built to link the Midwest to the Port of New York , a significant seaport during that time, by way of the Great Lakes , the canal, the Mohawk River , and the Hudson River. The completion of the canal enhanced the development of the American West, allowing settlers to travel west, send goods to markets in frontier cities, and export goods via
15471-653: The 21st century. The river was called Ka’nón:no or Ca-ho-ha-ta-te-a ("the river") by the Haudenosaunee , and it was known as Muh-he-kun-ne-tuk ("river that flows two ways" or "waters that are never still") or Mahicannittuk by the Mohican nation who formerly inhabited both banks of the lower portion of the river. The meaning of the Mohican name comes from the river's long tidal range. The Delaware Tribe of Indians (Bartlesville, Oklahoma) considers
15662-608: The Algonquians called wigwams , though large families often lived in longhouses that could be a hundred feet long. At the associated villages, they grew corn, beans, and squash. They also gathered other types of plant foods, such as hickory nuts and many other wild fruits and tubers. In addition to agriculture, the Algonquians also fished in the Hudson River, focusing on various species of freshwater fish, as well as various variations of striped bass , American eels , sturgeon , herring , and shad . Oyster beds were also common on
15853-698: The Battery , the river proper ends, meeting the East River to form Upper New York Bay, also known as New York Harbor . Its outflow continues through the Narrows between Brooklyn and Staten Island , under the Verrazzano Bridge , and into Lower New York Bay and the Atlantic Ocean through the Hudson Canyon . The lower Hudson is a tidal estuary, with tidal influence extending as far as
16044-548: The British against the French and their Indian allies. In 1761, Killbuck led a British supply train from Fort Pitt to Fort Sandusky . In 1763, Bill Hickman, a Lenape, warned English colonists in the Juniata River region of present-day Pennsylvania of an impending attack. After the end of the French and Indian War, European settlers continued to attack the Lenape, often to such an extent that, as historian Amy Schutt writes,
16235-602: The British, who had invaded the largely-defenseless New Amsterdam. New Amsterdam and the colony of New Netherland were renamed New York, after the Duke of York . Under British colonial rule, the Hudson Valley became an agricultural hub. Manors were developed on the east side of the river, and the west side contained many smaller and independent farms. In 1754, the Albany Plan of Union was created at Albany City Hall on
16426-727: The Confederation until 1753, shortly before the outbreak of the French and Indian War (a part of the Seven Years' War in Europe). The historical record of the mid-17th century suggests that most Lenape polities each consisted of several hundred people but it is conceivable that some had been considerably larger prior to close contact, given the wars between the Susquehannocks and the Iroquois, both of whom were armed by
16617-604: The Delaware Tribe of Indians received grant money to fund The Lenape Talking Dictionary , preserving and digitizing the Southern Unami dialect. At the time of European settlement in North America , a Lenape would have identified primarily with their immediate family and clan, friends, and village unit and, after that, with surrounding and familiar village units followed by more distant neighbors who spoke
16808-415: The Dutch and Swedes, were surprised at the Lenape's skill in fashioning clothing from natural materials. In hot weather men and women wore only loin cloth and skirt respectively, while they used beaver pelts or bear skins to serve as winter mantles. Additionally, both sexes might wear buckskin leggings and moccasins in cold weather. Women would wear their hair long, usually below the hip, while men kept only
16999-411: The Dutch arrival, they began to exchange wampum for beaver furs provided by Iroquoian -speaking Susquehannock and other Minquas. They exchanged these furs for Dutch and, from the late 1630s, also Swedish imports. Relations between some Lenape and Minqua polities briefly turned sour in the late 1620s and early 1630s, but were relatively peaceful most of the time. The early European settlers, especially
17190-678: The Dutch fur traders, while the Lenape were at odds with the Dutch and so lost that particular arms race. In 1648, the Axion band of Lenape were the largest tribe on the Delaware River, with 200 warriors. Epidemics of newly introduced European infectious diseases , such as smallpox , measles, cholera, influenza, and dysentery, reduced the populations of Lenape. They and other Native peoples had no natural immunity . Recurrent violent conflicts with Europeans also devastated Lenape people. In 1682, William Penn and Quaker colonists created
17381-405: The Dutch shifted their operations to present-day upstate New York . The Lenape who produced wampum in the vicinity of Manhattan Island temporarily forestalled the negative effects of the decline in trade. During the resulting Beaver Wars in the first half of the 17th century, European colonists were careful to keep firearms from the coastally located Lenape, while rival Iroquoian peoples in
17572-617: The Dutch was Rio de Montaigne . Later, they generally termed it the Noortrivier , or " North River ", the Delaware River being known as the Zuidrivier , or "South River". Other occasional names for the Hudson included Manhattes rieviere "Manhattan River", Groote Rivier "Great River", and de grootte Mouritse reviere , or "the Great Maurits River" (after Maurice, Prince of Orange ). The translated name North River
17763-606: The English colony of Pennsylvania beginning at the lower Delaware River . A peace treaty was negotiated between the newly arriving colonists and Lenape at what is now known as Penn Treaty Park . In the decades immediately following, some 20,000 new colonists arrived in the region, putting pressure on Lenape settlements and hunting grounds. Penn expected his authority and that of the colonial Province of Pennsylvania government to take precedence. William Penn died in 1718. His heirs, John and Thomas Penn, and their agents were ruling
17954-620: The Hudson River and New York City. The completion of the canal made New York City one of the most vital ports in the nation, surpassing the Port of Philadelphia and ports in Massachusetts . After the completion of the Erie Canal, smaller canals were built to connect it with the new system. The Champlain Canal was built to connect the Hudson River near Troy to the southern end of Lake Champlain. This canal allowed boaters to travel from
18145-588: The Hudson River from terminating via the Narrows. At that time, the Hudson River emptied into the Atlantic Ocean through a more westerly course through parts of present-day northern New Jersey, along the eastern side of the Watchung Mountains to Bound Brook, New Jersey and then on into the Atlantic Ocean via Raritan Bay . A buildup of water in the Upper New York Bay eventually allowed the Hudson River to break through previous land mass that
18336-425: The Hudson River, and would later become Kingston. Fort Orange was founded on the river north of Wiltwyck, and later became known as Albany. The Dutch West India Company operated a monopoly on the region for roughly twenty years before other businessmen were allowed to set up their own ventures in the colony. In 1647, Director-General Peter Stuyvesant took over management of the colony, and surrendered it in 1664 to
18527-405: The Hudson and a metal chain between the two. In 1777, Washington expected the British would attempt to control the Hudson River, however they instead conquered Philadelphia, and left a smaller force in New York City, with permission to strike the Hudson Valley at any time. The British attacked on October 5, 1777, in the Battle of Forts Clinton and Montgomery by sailing up the Hudson River, looting
18718-537: The Hudson. The plan allowed the colonies to treaty with the Iroquois and provided a framework for the Continental Congress . During the American Revolutionary War , the British realized that the river's proximity to Lake George and Lake Champlain would allow their navy to control the water route from Montreal to New York City. British general John Burgoyne planned the Saratoga campaign , to control
18909-532: The Langerack by the Dutch. An embellished (and partly erroneous) list of "The Old Reaches" was published in a tourist guidebook for steamboat passengers in the nineteenth century. The source of the Hudson River is Henderson Lake , located in the Adirondack Mountains at an elevation of 4,322 ft (1,317 m). However, the photogenic Lake Tear of the Clouds is more conventionally cited in popular culture as
19100-528: The Lenape adapted to European methods of hunting and farming with metal tools. The men limited their agricultural labor to clearing the field and breaking the soil. They primarily hunted and fished during the rest of the year: from September to January and from June to July, they mainly hunted deer, but from the month of January to the spring planting in May, they hunted anything from bears and beavers to raccoons and foxes. Dutch settler David de Vries , who stayed in
19291-529: The Lenape for agricultural products, mainly maize, in exchange for iron tools. The Lenape also arranged contacts between the Minquas or Susquehannocks and the Dutch West India Company and Swedish South Company to promote the fur trade . The Lenape were major producers of labor intensive wampum , or shell beads, which they traditionally used for ritual purposes and as ornaments. After
19482-591: The Lenape historical territory, which spanned what is now eastern Pennsylvania , New Jersey , Lower New York Bay , and eastern Delaware . The tribe's common name Delaware comes from the French language . English colonists named the Delaware River for the first governor of the Province of Virginia , Lord De La Warr . The British colonists began to call the Lenape the Delaware Indians because of where they lived. Swedish colonists also settled in
19673-466: The Lenape in 1682, said the Unami used the following words: "mother" was anna , "brother" was isseemus and "friend" was netap . He instructed his fellow English colonists: "If one asks them for anything they have not, they will answer, mattá ne hattá , which to translate is, 'not I have,' instead of 'I have not'." The Lenape languages were once exclusively spoken languages. In 2002,
19864-401: The Lenape people that lived there. The Lenape had a culture in which the clan and family controlled property. Europeans often tried to contract for land with the tribal chiefs, confusing their culture with that of neighboring tribes such as the Iroquois . As a further complication in communication and understanding, kinship terms commonly used by European settlers had very different meanings to
20055-550: The Lenape: "fathers" did not have the same direct parental control as in Europe, "brothers" could be a symbol of equality but could also be interpreted as one's parallel cousins, "cousins" were interpreted as only cross-cousins, etc. All of these added complexities in kinship terms made agreements with Europeans all the more difficult. The Lenape would petition for grievances on the basis that not all their families had been recognized in
20246-646: The Mohawk River, drain an area of 13,000 square miles (34,000 km), the Hudson River Watershed. It covers much of New York, as well as parts of Connecticut, Massachusetts, New Jersey, and Vermont. Parts of the Hudson River form coves , such as Weehawken Cove in the towns of Hoboken and Weehawken in New Jersey. The City of Poughkeepsie and several adjacent communities in the mid-Hudson valley, totalling about 100,000 people, rely on
20437-553: The Pennsylvania government that is commonly known as the Walking Purchase". In the end, all Lenape who still lived on the Delaware were driven off the remnants of their homeland under threats of violence. Some Lenape polities eventually retaliated by attacking Pennsylvania settlements. When they resisted European colonial expansion at the height of the French and Indian War , British colonial authorities investigated
20628-640: The Storykeeper of the Lenape Nation of Pennsylvania , calls the name "an anglicized grammatical error that basically translates as the 'original people people.'" While acknowledging that some Lenape do identify as Lenni Lenape or Delaware, DePaul says "the best word to use when referring to us is simply 'Lenape.'" When first encountered by European settlers, the Lenape were a loose association of closely related peoples who spoke similar languages and shared familial bonds in an area known as Lenapehoking ,
20819-518: The Turtle or Wolf clans. His children would not belong to the Turkey Clan, but to the mother's clan. As such, a person's mother's brothers (the person's matrilineal uncles) played a large role in his or her life as they shared the same clan lineage. Within a marriage itself, men and women had relatively separate and equal rights, each controlling their own property and debts, showing further signs of
21010-550: The area from 1634 to 1644, described a Lenape hunt in the valley of the Achinigeu-hach (or Ackingsah-sack, the Hackensack River ), in which 100 or more men stood in a line many paces from each other, beating thigh bones on their palms to drive animals to the river, where they could be killed easily. Other methods of hunting included lassoing and drowning deer, as well as forming a circle around prey and setting
21201-575: The area of present-day Washington Valley in Morris County, New Jersey . Led by Reverend John Brainerd, colonists forcefully relocated 200 people to Indian Mills, then known as Brotherton , an industrial town with gristills and sawmills, that was the first Native American reservation in New Jersey . Reverend John Brainerd abandoned the reservation in 1777. In 1758, the Treaty of Easton
21392-694: The area, and Swedish sources called the Lenape the Renappi . The historical Lenape country, Lenapehoking ( Lënapehòkink ), was a large territory that encompassed the Delaware and Lehigh Valley regions of eastern Pennsylvania and New Jersey from the north bank of the Lehigh River along the west bank of the Delaware River into Delaware and the Delaware Bay . Their lands also extended west from western Long Island and New York Bay , across
21583-500: The area. Beginning in the 18th century, the Moravian Church established missions in Lenape settlements. The Moravians required the Christian converts to share Moravian pacifism and live in a structured and European-style mission village. Moravian pacifism and unwillingness to take loyalty oaths caused conflicts with British colonial authorities, who were seeking aid against the French and their Native American allies in
21774-695: The bodies of humans and animals worldwide, as well as in the soil, with potentially negative health effects. Research into how to remove it from the environment, and how harmful exposure is, is ongoing. Fertilizer from farms can lead to a proliferation of algae on the surface of rivers and oceans, which prevents oxygen and light from dissolving into water, making it impossible for underwater life to survive in these so-called dead zones . Urban rivers are typically surrounded by impermeable surfaces like stone, asphalt , and concrete. Cities often have storm drains that direct this water to rivers. This can cause flooding risk as large amounts of water are directed into
21965-736: The boundary between Orange and Dutchess Counties. It flows between Newburgh and Beacon and under the Newburgh Beacon Bridge , taking in the Fishkill Creek . In this area, between Gee's Point at the US Military Academy and Constitution Island , an area known as "World's End" marks the deepest part of the Hudson, at 202 feet (62 m). Shortly thereafter, the river enters the Hudson Highlands between Putnam and Orange Counties, flowing between mountains such as Storm King Mountain , Breakneck Ridge , and Bear Mountain . The river narrows considerably here before flowing under
22156-669: The boundary between Ulster and Columbia Counties and Ulster and Dutchess Counties, passing Germantown and Kingston . The Delaware and Hudson Canal meets the river at this point. The river then flows by Hyde Park , former residence of Franklin D. Roosevelt , and alongside the city of Poughkeepsie , flowing under the Walkway over the Hudson and the Mid-Hudson Bridge . Afterwards, the Hudson passes Wappingers Falls and takes in Wappinger Creek . The river then forms
22347-494: The brush on fire. They also harvested vast quantities of fish and shellfish from the bays of the area, and, in southern New Jersey, harvested clams year-round. One technique used while fishing was to add ground chestnuts to stream water to make fish dizzy and easier to catch. The success of these methods allowed the tribe to maintain a larger population than other, nomadic hunter-gatherer peoples in North America at
22538-642: The causes of Lenape resentment. The British asked Sir William Johnson , Superintendent of Indian Affairs, to lead the investigation. Johnson had become wealthy as a trader and acquired thousands of acres of land in the Mohawk River region from the Iroquois Mohawk of New York. In 1757, an organization known as the New Jersey Association for Helping the Indians wrote a constitution to expel native Munsee Lenape from their settlements in
22729-643: The city of Troy , the flow of the river changes direction with the tides. The Hudson River runs through the Munsee , Lenape , Mohican , Mohawk , and Haudenosaunee homelands. Prior to European exploration, the river was known as the Mahicannittuk by the Mohicans, Ka'nón:no by the Mohawks, and Muhheakantuck by the Lenape. The river was subsequently named after Henry Hudson , an Englishman sailing for
22920-699: The closely related Mohicans to be a part of the Lenape people, and so the Lenape also claim the Hudson as part of their ancestral territory, also calling it Muhheakantuck . The first known European name for the river was the Rio San Antonio as named by the Portuguese explorer in Spain's employ, Estêvão Gomes , who explored the Mid-Atlantic coast in 1525. Another early name for the Hudson used by
23111-427: The colony, and had abandoned many of William Penn 's practices. In an attempt to raise money, they contemplated ways to sell Lenape land to colonial settlers, which culminated in the Walking Purchase . In the mid-1730s, colonial administrators produced a draft of a land deed dating to the 1680s. William Penn had approached several leaders of Lenape polities in the lower Delaware to discuss land sales further north. Since
23302-405: The complete draining of rivers. Limits on the construction of dams, as well as dam removal , can restore the natural habitats of river species. Regulators can also ensure regular releases of water from dams to keep animal habitats supplied with water. Limits on pollutants like pesticides can help improve water quality. Today, the surface of Mars does not have liquid water. All water on Mars
23493-414: The dead since the wars outnumbered those killed during the war. In April 1763, Teedyuscung was killed during the burning of his home. His son Captain Bull responded by attacking settlers, sponsored by the Susquehanna Company, in the present-day Wyoming Valley region of Pennsylvania.. Many Lenape joined in Pontiac's War and were among the Native Americans who besieged present-day Pittsburgh. During
23684-581: The early 1770s, missionaries, including David Zeisberger and John Heckewelder , arrived in the Ohio Country near the Lenape villages. The Moravian Church sent these men to convert the Indigenous peoples to Christianity. The missionaries established several missions, including Gnadenhutten , Lichtenau , and Schoenbrunn . The missionaries pressured Indigenous people to abandon their traditional customs , beliefs, and ways of life, and to replace them with European and Christian ways. Many Lenape did adopt Christianity, but others refused to do so. The Lenape became
23875-428: The early 19th century United States. Pollution in the Hudson River increased in the 20th century, more acutely by mid-century, particularly with industrial contamination from polychlorinated biphenyls , also known by their acronym PCBs. Pollution control regulations, enforcement actions and restoration projects initiated in the latter 20th century have begun to improve water quality, and restoration work has continued in
24066-436: The effect of normalizing the effects of rivers; the greatest floods are smaller and more predictable, and larger sections are open for navigation by boats and other watercraft. A major effect of river engineering has been a reduced sediment output of large rivers. For example, the Mississippi River produced 400 million tons of sediment per year. Due to the construction of reservoirs , sediment buildup in man-made levees , and
24257-426: The end of the 17th century, each of which historically had twelve sub-clans: The Lenape have a matrilineal clan system and historically were matrilocal . Children belong to their mother's clan, from which they gain social status and identity. The mother's eldest brother was more significant as a mentor to the male children than was their father, who was generally of another clan. Hereditary leadership passed through
24448-451: The fish zonation concept. Smaller rivers can only sustain smaller fish that can comfortably fit in its waters, whereas larger rivers can contain both small fish and large fish. This means that larger rivers can host a larger variety of species. This is analogous to the species-area relationship , the concept of larger habitats being host to more species. In this case, it is known as the species-discharge relationship, referring specifically to
24639-606: The floating of wood on rivers to transport it, was especially important. Rivers also were an important source of drinking water . For civilizations built around rivers, fish were an important part of the diet of humans. Some rivers supported fishing activities, but were ill-suited to farming, such as those in the Pacific Northwest . Other animals that live in or near rivers like frogs , mussels , and beavers could provide food and valuable goods such as fur . Humans have been building infrastructure to use rivers for thousands of years. The Sadd el-Kafara dam near Cairo , Egypt,
24830-412: The flow of the river beneath its surface. These help rivers flow straighter by increasing the speed of the water at the middle of the channel, helping to control floods. Levees are also used for this purpose. They can be thought of as dams constructed on the sides of rivers, meant to hold back water from flooding the surrounding area during periods of high rainfall. They are often constructed by building up
25021-399: The flow, causing it to reflect in the other direction. Thus, a bend in the river is created. Rivers may run through low, flat regions on their way to the sea. These places may have floodplains that are periodically flooded when there is a high level of water running through the river. These events may be referred to as "wet seasons' and "dry seasons" when the flooding is predictable due to
25212-650: The form of leaves. In this type of ecosystem, collectors and shredders will be most active. As the river becomes deeper and wider, it may move slower and receive more sunlight . This supports invertebrates and a variety of fish , as well as scrapers feeding on algae. Further downstream, the river may get most of its energy from organic matter that was already processed upstream by collectors and shredders. Predators may be more active here, including fish that feed on plants, plankton , and other fish. The flood pulse concept focuses on habitats that flood seasonally, including lakes and marshes . The land that interfaces with
25403-450: The goddess Isis were said to be the cause of the river's yearly flooding, itself personified by the goddess Hapi . Many African religions regard certain rivers as the originator of life. In Yoruba religion , Yemọja rules over the Ogun River in modern-day Nigeria and is responsible for creating all children and fish. Some sacred rivers have religious prohibitions attached to them, such as not being allowed to drink from them or ride in
25594-422: The hamlet of North River , and takes in the Schroon River at Warrensburg . Further south, the river forms the boundary between Warren and Saratoga Counties. The river then takes in the Sacandaga River from the Great Sacandaga Lake . Shortly thereafter, the river leaves the Adirondack Park, flows under Interstate 87 , and through Glens Falls , just south of Lake George although receiving no streamflow from
25785-421: The interior of the Northeast to the coast. Hundreds of factories were built around the Hudson, in towns including Poughkeepise, Newburgh, Kingston, and Hudson. The North Tarrytown Assembly (later owned by General Motors ), on the river in Sleepy Hollow, was a large and notable example. The River links to the Erie Canal and Great Lakes, allowing manufacturing in the Midwest, including automobiles in Detroit, to use
25976-428: The irrigation of desert environments for growing food. Growing food at scale allowed people to specialize in other roles, form hierarchies, and organize themselves in new ways, leading to the birth of civilization. In pre-industrial society , rivers were a source of transportation and abundant resources. Many civilizations depended on what resources were local to them to survive. Shipping of commodities, especially
26167-426: The lake. It next goes through Hudson Falls . At this point the river forms the boundary between Washington and Saratoga Counties. Here the river has an elevation of 200 feet (61 m). Just south in Fort Edward , the river reaches its confluence with the Champlain Canal , which historically provided boat traffic between New York City and Montreal and the rest of Eastern Canada via the Hudson, Lake Champlain and
26358-445: The land in question did not belong to their polities, the talks did not lead to an agreement. But colonial administrators prepared the draft that resurfaced in the 1730s. The Penns and their supporters presented this draft as a legitimate deed, but Lenape leaders in the lower Delaware refused to accept it. According to historian Steven C. Harper , what followed was a "convoluted sequence of deception, fraud, and extortion orchestrated by
26549-409: The land, the houses, and the families, the clan fathers provided the meat, cleared the fields, built the houses, and protected the clan. Upon reaching adulthood, a Lenape male would marry outside of his clan . The practice effectively prevented inbreeding, even among individuals whose kinship was obscure or unknown. This means that a male from the Turkey Clan was expected to marry a female from either
26740-440: The landscape around it, forming deltas and islands where the flow slows down. Rivers rarely run in a straight line, instead, they bend or meander ; the locations of a river's banks can change frequently. Rivers get their alluvium from erosion , which carves rock into canyons and valleys . Rivers have sustained human and animal life for millennia, including the first human civilizations . The organisms that live around or in
26931-410: The last decades of the 18th century, European settlers and the effects of the American Revolutionary War displaced most Lenape from their homelands and pushed them north and west. In the 1860s, under the Indian removal policy, the U.S. federal government relocated most Lenape remaining in the Eastern United States to the Indian Territory and surrounding regions. Lenape people currently belong to
27122-434: The late summer, when there may be less snow left to melt, helping to ensure that the rivers downstream of the glaciers have a continuous supply of water. Rivers flow downhill, with their direction determined by gravity . A common misconception holds that all or most rivers flow from North to South, but this is not true. As rivers flow downstream, they eventually merge to form larger rivers. A river that feeds into another
27313-419: The level of river branching in a drainage basin. Several systems of stream order exist, one of which is the Strahler number . In this system, the first tributaries of a river are 1st order rivers. When two 1st order rivers merge, the resulting river is 2nd order. If a river of a higher order and a lower order merge, the order is incremented from whichever of the previous rivers had the higher order. Stream order
27504-561: The local ecosystems of rivers needed less protection as humans became less reliant on them for their continued flourishing. River engineering began to develop projects that enabled industrial hydropower , canals for the more efficient movement of goods, as well as projects for flood prevention . River transportation has historically been significantly cheaper and faster than transportation by land. Rivers helped fuel urbanization as goods such as grain and fuel could be floated downriver to supply cities with resources. River transportation
27695-459: The maternal line, and women elders could remove leaders of whom they disapproved. Agricultural land was managed by women and allotted according to the subsistence needs of their extended families. Newlywed couples would live with the bride's family, where her mother and sisters could also assist her with her growing family. By 1682, when William Penn arrived to his American commonwealth, the Lenape had been so reduced by disease, famine, and war that
27886-407: The mechanical shadoof began to be used to raise the elevation of water. Drought years harmed crop yields, and leaders of society were incentivized to ensure regular water and food availability to remain in power. Engineering projects like the shadoof and canals could help prevent these crises. Despite this, there is evidence that floodplain-based civilizations may have been abandoned occasionally at
28077-400: The migration routes of fish and destroy habitats. Rivers that flow freely from headwaters to the sea have better water quality, and also retain their ability to transport nutrient-rich alluvium and other organic material downstream, keeping the ecosystem healthy. The creation of a lake changes the habitat of that portion of water, and blocks the transportation of sediment, as well as preventing
28268-417: The most successful painters of the school. At the beginning of the 19th century, transportation from the US east coast into the mainland was difficult. Ships were the fastest vehicles at the time, as trains were still being developed and automobiles were roughly a century away. In order to facilitate shipping throughout the country's interior, numerous canals were constructed between internal bodies of water in
28459-413: The mouth of the river. The deeply eroded old riverbed beyond the current shoreline, Hudson Canyon , is a rich fishing area. The former riverbed is clearly delineated beneath the waters of the Atlantic Ocean, extending to the edge of the continental shelf . As a result of the glaciation and the rising sea levels , the lower half of the river is now a tidal estuary that occupies the Hudson Fjord. The fjord
28650-413: The narrow, meandering stretches as racks , or reaches. These names included the four "lower reaches" through the Hudson Highlands (Seylmakers rack, Cocks rack, Hoogh rack, and Vosserack) plus the four "upper reaches" from Inbocht Bay to Kinderhook (Backers rack, Jan Pleysiers rack, Klevers rack, and Harts rack). A ninth reach was described as "the long reach" by the Englishman Robert Juet and designated as
28841-399: The natural meandering of the river. Dams block the migration of fish such as salmon for which fish ladder and other bypass systems have been attempted, but these are not always effective. Pollution from factories and urban areas can also damage water quality. " Per- and polyfluoroalkyl substances (PFAS) is a widely used chemical that breaks down at a slow rate. It has been found in
29032-429: The natural terrain with soil or clay. Some levees are supplemented with floodways, channels used to redirect floodwater away from farms and populated areas. Dams restrict the flow of water through a river. They can be built for navigational purposes, providing a higher level of water upstream for boats to travel in. They may also be used for hydroelectricity , or power generation from rivers. Dams typically transform
29223-420: The north and west such as the Susquehannocks and Confederation of the Iroquois became comparatively well-armed. They defeated the Lenape, and some scholars believe that the Lenape may have become tributaries to the Susquehannock. After the warfare, the Lenape referred to the Susquehannock as "uncles". The Iroquois Confederacy added the Lenape to the Covenant Chain in 1676 and the Lenape were tributary to
29414-422: The nuts of Aesculus glabra in the pocket for rheumatism , and an infusion of ground nuts mixed with sweet oil or mutton tallow for earaches. They also grind the nuts and use them to poison fish in streams. They also apply a poultice of pulverized nuts with sweet oil for earache. The first recorded European contact with people presumed to have been the Lenape was in 1524. The explorer Giovanni da Verrazzano
29605-675: The other slightly forwards then backwards, yet so as to advance gradually". A number of linear measures were used. Small units of measure were the distance from the thumb and first finger, and the distance from first finger to pit of elbow. Travel distance was measured in the distance one could comfortably travel from sun-up to sun-down. Lenape herbalists , who have been primarily women, use their extensive knowledge of plant life to help heal their community's ailments, sometimes through ceremony. The Lenape found uses in trees like black walnut which were used to cure ringworm and with persimmons which were used to cure ear problems. The Lenape carry
29796-425: The plain show evidence of a river network, and even river deltas. These images reveal channels formed in the rock, recognized by geologists who study rivers on Earth as being formed by rivers, as well as "bench and slope" landforms, outcroppings of rock that show evidence of river erosion. Not only do these formations suggest that rivers once existed, but that they flowed for extensive time periods, and were part of
29987-408: The present-day Delaware River the South River , which formed the spine of the Dutch colony of New Netherland . Settlements 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. During the 18th century, the river valley and its inhabitants were
30178-404: The remaining wilderness, which was fast disappearing from the Hudson Valley just as it was coming to be appreciated for its qualities of ruggedness and sublimity . The school characterizes the artistic body, its New York location, its landscape subject matter, and often its subject, the Hudson River. In general, Hudson River School artists believed that nature in the form of the American landscape
30369-448: The removal of natural banks replaced with revetments , this sediment output has been reduced by 60%. The most basic river projects involve the clearing of obstructions like fallen trees. This can scale up to dredging , the excavation of sediment buildup in a channel, to provide a deeper area for navigation. These activities require regular maintenance as the location of the river banks changes over time, floods bring foreign objects into
30560-478: The reverse, death and destruction, especially through floods . This power has caused rivers to have a central role in religion , ritual , and mythology . In Greek mythology , the underworld is bordered by several rivers. Ancient Greeks believed that the souls of those who perished had to be borne across the River Styx on a boat by Charon in exchange for money. Souls that were judged to be good were admitted to Elysium and permitted to drink water from
30751-400: The river and therefore cut off the patriot hub of New England (to the river's east) from the South and Mid-Atlantic regions to the river's west. The action would allow the British to focus on rallying the support of loyalists in the southerly states. As a result, numerous battles were fought along the river and in nearby waterways. These include the Battle of Long Island , in August 1776 and
30942-514: The river floor, which provided an extra source of nutrition. Land hunting consisted of turkey, deer, bear, and other animals. The lower Hudson River was inhabited by the Lenape, while further north, the Wappingers lived from Manhattan Island up to Poughkeepsie . They traded with both the Lenape to the south and the Mahicans to the north. The Mahicans lived in the northern part of the valley from present-day Kingston to Lake Champlain , with their capital located near present-day Albany . John Cabot
31133-422: The river for their drinking water. New York Harbor, between the Narrows and the George Washington Bridge, has a mix of fresh and ocean water, mixed by wind and tides to create an increasing gradient of salinity from the river's top to its bottom. This varies with season, weather, variation of water circulation, and other factors; snowmelt at winter's end increases the freshwater flow downstream. The salt line of
31324-461: The river for transport. With industrialization came new technologies for transport, including steamboats for faster transport. In 1807, the North River Steamboat (later known as Clermont), became the first commercially successful steamboat. It carried passengers between New York City and Albany along the Hudson River. River A river is a natural freshwater stream that flows on land or inside caves towards another body of water at
31515-409: The river varies from the north in Poughkeepsie to the south at Battery Park in New York City, though it usually lies near Newburgh. The Hudson is sometimes called, in geological terms, a drowned river . The rising sea levels after the retreat of the Wisconsin glaciation , the most recent ice age , have resulted in a marine incursion that drowned the coastal plain and brought salt water well above
31706-405: The river, and natural sediment buildup continues. Artificial channels are often constructed to "cut off" winding sections of a river with a shorter path, or to direct the flow of a river in a straighter direction. This effect, known as channelization, has made the distance required to traverse the Missouri River in 116 kilometres (72 mi) shorter. Dikes are channels built perpendicular to
31897-552: The river. Areas of a river with softer rock weather faster than areas with harder rock, causing a difference in elevation between two points of a river. This can cause the formation of a waterfall as the river's flow falls down a vertical drop. A river in a permeable area does not exhibit this behavior and may even have raised banks due to sediment. Rivers also change their landscape through their transportation of sediment , often known as alluvium when applied specifically to rivers. This debris comes from erosion performed by
32088-569: The river. A country that is downstream of another may object to the upstream country diverting too much water for agricultural uses, pollution, as well as the creation of dams that change the river's flow characteristics. For example, Egypt has an agreement with Sudan requiring a specific minimum volume of water to pass into the Nile yearly over the Aswan Dam , to maintain both countries access to water. The importance of rivers throughout human history has given them an association with life and fertility . They have also become associated with
32279-457: The rivers themselves, debris swept into rivers by rainfall, as well as erosion caused by the slow movement of glaciers. The sand in deserts and the sediment that forms bar islands is from rivers. The particle size of the debris is gradually sorted by the river, with heavier particles like rocks sinking to the bottom, and finer particles like sand or silt carried further downriver . This sediment may be deposited in river valleys or carried to
32470-412: The rivers. Due to these impermeable surfaces, these rivers often have very little alluvium carried in them, causing more erosion once the river exits the impermeable area. It has historically been common for sewage to be directed directly to rivers via sewer systems without being treated, along with pollution from industry. This has resulted in a loss of animal and plant life in urban rivers, as well as
32661-427: The same dialect, and finally, with those in the surrounding area who spoke mutually comprehensible languages, including the Nanticoke people who lived to their south and west in present western Delaware and eastern Maryland . Among many Algonquian peoples along the East Coast , the Lenape were considered the grandfathers from whom other Algonquian -speaking peoples originated. The Lenape had three clans at
32852-409: The sea from their mouths. Depending on the activity of waves, the strength of the river, and the strength of the tidal current, the sediment can accumulate to form new land. When viewed from above, a delta can appear to take the form of several triangular shapes as the river mouth appears to fan out from the original coastline . In hydrology , a stream order is a positive integer used to describe
33043-414: The sea to breed in freshwater rivers are anadromous. Salmon are an anadromous fish that may die in the river after spawning, contributing nutrients back to the river ecosystem. Modern river engineering involves a large-scale collection of independent river engineering structures that have the goal of flood control , improved navigation, recreation, and ecosystem management. Many of these projects have
33234-404: The source of the Hudson. The river is named Feldspar Brook from where it emerges from Lake Tear of the Clouds until its confluence with the Opalescent River , after which it becomes the Opalescent until it reaches Calamity Brook flowing southward into the eastern outlet of Henderson Lake. After this point, the stream is known as the Hudson River according to the cartographical definition used by
33425-486: The southwest flowing Calamity Brook. The confluence of the two rivers however is where most maps begin to use the Hudson River name on a cartographical basis. South of the outlet of Sanford Lake, the Opalescent River flows into the Hudson. The Hudson then flows south, taking in Beaver Brook and the outlet of Lake Harris. After its confluence with the Indian River, the Hudson forms the boundary between Essex and Hamilton counties. The Hudson flows entirely into Warren County in
33616-519: The spread of waterborne diseases such as cholera . In modern times, sewage treatment and controls on pollution from factories have improved the water quality of urban rivers. Climate change can change the flooding cycles and water supply available to rivers. Floods can be larger and more destructive than expected, causing damage to the surrounding areas. Floods can also wash unhealthy chemicals and sediment into rivers. Droughts can be deeper and longer, causing rivers to run dangerously low. This
33807-435: The state line with New Jersey the west bank of the Hudson enters Bergen County . The Palisades are large, rocky cliffs along the west bank of the river; also known as Bergen Hill at their lower end in Hudson County . Further south the east bank of the river becomes Yonkers and then the Riverdale neighborhood of the Bronx in New York City. South of the confluence of the Hudson and Spuyten Duyvil Creek (subsumed by
33998-412: The sub-clan mothers had reluctantly resolved to consolidate their families into the main clan family. This is why William Penn and all those after him believed that the Lenape clans had always only had three divisions (Turtle, Turkey, and Wolf) when, in fact, they had over thirty on the eve of European contact. Members of each clan were found throughout Lenape territory, and while clan mothers controlled
34189-436: The subject and inspiration of Washington Irving , the first internationally acclaimed American author. In the nineteenth century, the area inspired the Hudson River School of landscape painting , an American pastoral style, as well as the concepts of environmentalism and wilderness . The Hudson River was also the eastern outlet for the Erie Canal , which, when completed in 1825, became an important transportation artery for
34380-410: The surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins , areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes
34571-438: The tides. The Mahican name of the river represents its partially estuarine nature: muh-he-kun-ne-tuk means "the river that flows both ways." Due to tidal influence from the ocean extending to Troy, NY, freshwater discharge is only about 17,400 cubic feet (490 m) per second on average. The mean fresh water discharge at the river's mouth in New York is approximately 21,900 cubic feet (620 m) per second. The Hudson River
34762-447: The time, could support. Scholars have estimated that at the time of European settlement, around much of the current New York City area alone, there may have been about 15,000 Lenape in approximately 80 settlement sites. In 1524, Lenape in canoes met Giovanni da Verrazzano , the first European explorer to enter New York Harbor . European settlers and traders from the 17th-century colonies of New Netherland and New Sweden traded with
34953-402: The transaction (not that they wanted to "share" the land). After the Dutch arrival and brief establishment of Fort Nassau (along the bank of the Delaware River in present day Gloucester City, New Jersey ) in the 1620s, the Lenape were successful in restricting Dutch settlement until the 1660s to no further than Pavonia in present-day Jersey City along the Hudson. The Dutch finally established
35144-409: The vicinity of present-day Albany, reaching an end to navigation. The Dutch subsequently began to colonize the region, establishing the colony of New Netherland , including three major fur-trading outposts: New Amsterdam , Wiltwyck , and Fort Orange . New Amsterdam was founded at the mouth of the Hudson River, and would later become known as New York City . Wiltwyck was founded roughly halfway up
35335-453: The village of Peekskill and capturing the two forts. In 1778, the Continentals constructed the Great West Point Chain in order to prevent another British fleet from sailing up the Hudson. Hudson River School paintings reflect the themes of discovery, exploration, and settlement in America in the mid-19th century. The detailed and idealized paintings also typically depict a pastoral setting. The works often juxtapose peaceful agriculture and
35526-421: The war. When the war began, Killbuck found the Lenape caught between the British and their Indian allies in the West and the Americans in the East. The Lenape were living in numerous villages around their main village of Coshocton , between the western frontier strongholds of the British and the Patriots. The Americans had Fort Pitt (present-day Pittsburgh) and the British, along with Indian allies, controlled
35717-458: Was an ineffable manifestation of God, though the artists varied in the depth of their religious conviction. Their reverence for America's natural beauty was shared with contemporary American writers such as Henry David Thoreau and Ralph Waldo Emerson . The artist Thomas Cole is generally acknowledged as the founder of the Hudson River School , his work first being reviewed in 1825, while painters Frederic Edwin Church and Albert Bierstadt were
35908-434: Was connecting Staten Island and Brooklyn to form the Narrows as it exists today. This allowed the Hudson River to find a shorter route to the Atlantic Ocean via its present course between New Jersey and New York City. Suspended sediments, mainly consisting of clays eroded from glacial deposits and organic particles, can be found in abundance in the river. The Hudson has a relatively short history of erosion, so it does not have
36099-408: Was greeted by local Lenape who came by canoe, after his ship entered what is now called Lower New York Bay . At the time of sustained European contact in the 17th through the 19th centuries, the Lenape were a powerful Native American nation who inhabited a region on the mid-Atlantic coast spanning the latitudes of southern Massachusetts to the southern extent of Delaware in what anthropologists call
36290-403: Was signed between the Lenape and European colonists. In it, the Lenape were required to move westward out of present-day New York and New Jersey, progressing into Pennsylvania and then to present-day Ohio and beyond. Through the 18th century, many Lenape moved west into the relatively depopulated upper Ohio River basin, but they also sporadically launched violent raids on settlers far outside
36481-431: Was used in the New York metropolitan area up until the early 1900s, with limited use continuing into the present day. The term persists in radio communication among commercial shipping traffic, especially below the Tappan Zee . The term also continues to be used in names of facilities in the river's southern portion, such as the North River piers , North River Tunnels , and the North River Wastewater Treatment Plant . It
