In the 18th century, William Penn , the founder of the Pennsylvania Colony , negotiated with the Lenape to allow white settlement in the area between the Delaware River and the Susquehanna, which was part of Lenape territory. In late colonial times, the river became an increasingly important transportation corridor, used to ship anthracite coal , discovered by Necho Allen , from its upper reaches in
3885-822: The railroad industry by the 1850s resulted in reducing the reliance on the river for transport. Two canal systems were constructed on the lower Susquehanna to bypass the rapids. The first was the Susquehanna Canal , also called the Conowingo Canal or the Port Deposit Canal, completed in 1802 by a Maryland company known as the Proprietors of the Susquehanna Canal. The second was the much longer and more successful Susquehanna and Tidewater Canal . The canals required dams to provide canal water and navigation pools. As

8436-548: The line again through the twin towns of Waverly, New York , and Sayre, Pennsylvania , and their large right bank railyard, once briefly holding the largest structure in the United States devoted to the maintenance and construction of railroad locomotives. A couple of miles south, in Athens Township, Pennsylvania , it receives the Chemung from the northwest. It makes a right-angle curve between Sayre and Towanda to cut through
8547-451: 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 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
8658-403: The main stem of the Susquehanna as impaired ." The Susquehanna River has attracted boaters who watch or fish for its migratory species. Many tourists and local residents use the Susquehanna in the summer for recreation purposes such as kayaking, canoeing, and motor-boating. Due to the high volume of smallmouth bass in the river, it is the host of numerous bass fishing tournaments each year and
8769-463: 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
8880-531: The mountains to the markets downriver. In 1779 during the American Revolutionary War , General James Clinton led an expedition down the Susquehanna from its headwaters. His party had made the upper portion navigable by damming the river's source at Otsego Lake , allowing the lake's level to rise, and then destroying the dam and flooding the river in order for his flotilla to travel for miles downstream. James Fenimore Cooper described this event in
8991-526: 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
9102-480: 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
9213-406: The northeast. It crosses into northern Maryland approximately 30 miles (48 km) northeast of Baltimore and is joined by Octoraro Creek from the northeast and Deer Creek from the northwest. The river enters the northern end of the Chesapeake Bay at Havre de Grace . Concord Point Light was built here in 1827 to accommodate the increasing navigational traffic. "Susquehanna" may come from
9324-578: The outlet of Otsego Lake in Cooperstown, New York . From there, the north branch of the river runs west-southwest through rural farmland and dairy country, receiving the Unadilla River at Sidney . It dips south into Pennsylvania briefly to turn sharply 90 degrees west at Susquehanna and again 90 degrees north at Great Bend hooking back into New York . It receives the Chenango in downtown Binghamton . After meandering westwards, it turns south crossing
9435-554: The powerful Five Nations of the Iroquois League based in present-day New York, who wanted to control the fur trade with Europeans. The Susquehannock assimilated with the Iroquois. In the aftermath, the Iroquois resettled some of the semi-tributary Lenape in this area, as it was near the western boundary of the Lenape's former territory, known as Lenapehoking . The Susquehanna River has continued to play an important role throughout
9546-513: 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
9657-499: 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
9768-523: The river at several locations in Cumberland and York counties. In 1972 the remnants of Hurricane Agnes stalled over the New York-Pennsylvania border, dropping as much as 20 inches (510 mm) of rain on the hilly lands. Much of that precipitation was received into the Susquehanna from its western tributaries, and the valley suffered disastrous flooding. Wilkes-Barre, Pennsylvania , was among
9879-623: 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
9990-541: 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
10101-575: 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 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,
10212-615: The river meant that while commercial traffic could navigate down the river in the high waters of the spring thaws, nothing could move up. The Susquehanna was improved by navigations throughout the 1820s and 1830s as the Pennsylvania Canal . Together with facilities of the Allegheny Portage Railroad , loaded barges were transferred from the canal and hoisted across the mountain ridge into the Pittsburgh area with access to
10323-573: 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
10434-655: 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 the Dutch East India Company who explored it in 1609, and after whom Hudson Bay in Canada is also named. It had previously been observed by Italian explorer Giovanni da Verrazzano sailing for King Francis I of France in 1524, as he became
10545-602: The river, in the Southern Tier of New York. The Appalachian Trail passes through Duncannon, Pennsylvania , and crosses the Susquehanna on the Clarks Ferry Bridge . Hudson River 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
10656-476: The river. Sampling began in 1979 before the first start-up of the PPL Susquehanna power plant. Although all species were not continuously monitored for the entire period, an extensive database was compiled. In May 1986, ongoing measurements from several monitoring stations along the river near Three Mile Island, Peach Bottom and Calvert Cliffs detected iodine-131 beta particles attributable to fallout from
10767-466: 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
10878-617: The southeast and passes Karthaus (at Mosquito Creek), Keating (at Sinnemahoning Creek), Renovo and Lock Haven , where it receives Bald Eagle Creek . At Jersey Shore, Pennsylvania, Pine Creek, the largest tributary of the West Branch Susquehanna River, is received. Pine Creek has the largest watershed of all the West Branch’s tributaries. It passes Williamsport , where both Lycoming Creek and Loyalsock Creek empty into it, then turns south, passing Lewisburg , before joining
10989-656: 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
11100-589: 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
11211-495: 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
11322-527: 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 a physical boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties . The lower half of
11433-413: 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
11544-625: 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
11655-456: Was also the eastern outlet for the Erie Canal , which, when completed in 1825, became an important transportation artery for 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
11766-573: 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
11877-435: 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
11988-478: Was designated as one of the American Heritage Rivers in 1997. The designation provides for technical assistance from federal agencies to state and local governments working in the Susquehanna watershed. Another environmental concern is radioactivity released during the 1979 Three Mile Island accident . However, extensive radionuclide studies over a 25-year period from 1979 through 2003, confirm that
12099-498: Was known as the "Sullivan-Clinton Campaign" or the " Sullivan Expedition ". They swept through western New York, dominated by the Seneca people , destroying more than 40 Seneca villages, as well as the stores of crops the people had set aside for winter. Many of the Iroquois left New York and went to Canada as refugees; casualties from exposure and starvation were high that winter. Following
12210-1044: 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 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
12321-563: 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
