149-774: Spuyten Duyvil Creek ( / ˈ s p aɪ t ən ˈ d aɪ v əl / ) is a short tidal estuary in New York City connecting the Hudson River to the Harlem River Ship Canal and then on to the Harlem River . The confluence of the three water bodies separate the island of Manhattan from the Bronx and the rest of the mainland. Once a distinct, turbulent waterway between the Hudson and Harlem rivers,

298-458: A metamorphic rock that is very hard to weather . The Tibbetts Brook valley is set in Inwood marble , which weathers more easily. The east side of the park near Indian Field contains Yonkers granite, an igneous rock that mixed with Fordham gneiss as a hot magma before later cooling. Van Cortlandt Park contains the Bronx's largest freshwater lake , the eponymous Van Cortlandt Lake. The lake

447-504: A nursery needed to be built to transport the plants during the garden's reconstruction. The rustic wooden bridges were to be replaced with stone bridges, while the wooden stairs were to be superseded by stone stairs. Not only did many plants die during the process, but the actual rebuilding was delayed until 1911. Two years later, the Parks Commissioner for the Bronx refused to allocate reconstruction funds because, he stated,

596-626: A 1910s excavation for a sewer pipe, stones were unearthed that were suspected to be from the old van der Donck estate. During World War I , the Parade Ground was used to train soldiers. Eight tennis courts opened in 1914 with admission being $ 1 per person, and owing to the Van Cortlandt Golf Course's immense popularity, the Mosholu Links also opened that year. By 1917, the Parade Ground contained 10 out of

745-399: A boat. To thwart robbers, besieged golfers quit playing in traditional foursomes and instead ventured forth in football-team-sized units. Some players added an extra club—a night stick—or tucked tear gas spray into their golf bags." Years later, one writer recalled that dozens of the course's trees died, and "flagsticks were reduced to broken bamboo poles stuck into the ground." Weeds overgrew

894-504: A depth of 15 feet (4.6 m) to 18 feet (5.5 m). It would be cut directly through the rock of Dyckman's Meadow, making a straight course to the Hudson River. The first section of the canal, the cut at Marble Hill, was completed in 1895 and opened on June 17 of that year. Several festivities including parades were held to commemorate the occasion. At this time, Tibbets Brook was diverted into storm drains underneath Broadway, with

1043-573: A harsh environment for organisms. Sediment often settles in intertidal mudflats which are extremely difficult to colonize. No points of attachment exist for algae , so vegetation based habitat is not established. Sediment can also clog feeding and respiratory structures of species, and special adaptations exist within mudflat species to cope with this problem. Lastly, dissolved oxygen variation can cause problems for life forms. Nutrient-rich sediment from human-made sources can promote primary production life cycles, perhaps leading to eventual decay removing

1192-407: A local landowner. Many settlers circumvented the toll for the ferry by crossing the creek from northern Marble Hill to modern Kingsbridge, Bronx , a point where it was feasible to wade or swim through the waters. This area was known as the "wading place", and had previously been used by Native Americans. In response, Verveelen had the creek fenced off at the wading place, though travelers simply tore

1341-556: A need for a larger water supply. Major David Bates Douglass was appointed to perform engineering studies on the future Old Croton Aqueduct in March 1833. Douglass made estimates for the new aqueduct in 1833–1834 and John Martineau performed a separate study in 1834. Both found the proposed route, which ran through the present-day park, to be okay. Thus, in 1837, construction started on the Aqueduct, which ran 41 miles (66 km) from

1490-529: A number of coastal water bodies such as coastal lagoons and brackish seas. A more comprehensive definition of an estuary is "a semi-enclosed body of water connected to the sea as far as the tidal limit or the salt intrusion limit and receiving freshwater runoff; however the freshwater inflow may not be perennial, the connection to the sea may be closed for part of the year and tidal influence may be negligible". This broad definition also includes fjords , lagoons , river mouths , and tidal creeks . An estuary

1639-410: A reference to the strong and wild tidal currents found at that location. It may also be translated as "Spewing Devil" or "Spinning Devil", or more loosely as "Devil's Whirlpool" or "Devil's Spate." Spui is a Dutch word involving outlets for water. Historian Reginald Pelham Bolton , however, argues that the phrase means "sprouting meadow", referring to a fresh-water spring. A folk etymology , "to spite

1788-478: A sawmill, creating a mill pond at the site where the lake is. Later, he also added a gristmill. The sawmill was relocated around 1823 and stayed in operation until 1889. The gristmill was destroyed by lightning in 1901. By the time the park was created, Van Cortlandt Lake needed to be cleaned, as cesspools in Yonkers had leaked sewage into Tibbetts Brook, which fed into the lake. A 1903 annual report from

1937-423: A series of culverts before draining into the south edge of the lake at approximately West 242nd Street. There are efforts to daylight this south end into the former New York and Putnam Railroad right-of-way that runs through the park as part of the park's faster plan. There is no surviving documentation for the creation of Van Cortlandt Lake. In 1699, Jacobus Van Cortlandt dammed Tibbetts Brook to power

2086-549: A sprawling lawn dubbed the "Parade Ground," while the Van Cortlandt House was converted into a public museum. The construction of the Parade Ground required demolition of a few old buildings and cornfields. The Parade Ground was immediately used by the National Guard for brigade practice, replacing the parade ground of Prospect Park . The ground received unspecified "improvements" in 1893–1894. With

2235-415: A study to determine the specific elements of the park that needed restoration. Highway structures were also reconfigured to clean runoff from these structures. An excavation in the 1990s yielded over 2,500 artifacts. A set of tennis courts were proposed within the park east of the Van Cortlandt House in the 1990s; despite concerns from preservationists, though the courts were approved. The city built

2384-698: A survey of the relevant area, following which New York state bought the necessary land and gave it to the federal government. In 1876, the New York State Legislature issued a decree for the construction of the canal. Construction of the Harlem River Ship Canal – officially the United States Ship Canal – finally started in January 1888. The canal would be 400 feet (120 m) in width and have

2533-484: A third of their original demand of $ 11.53 million. Plans to excavate the channel were finalized in 1935, and the channel was excavated from 1937 to 1938. The work severed the Johnson foundry's 13.5-acre (5.5 ha) peninsula of land from the Bronx, which was then absorbed into Manhattan's Inwood Hill Park ; the peninsula now contains the park's Nature Center. Today, Spuyten Duyvil Creek, the Harlem River Ship Canal, and

2682-408: A type of ecosystem in some estuaries that have been negatively impacted by eutrophication. Cordgrass vegetation dominates the salt marsh landscape. Excess nutrients allow the plants to grow at greater rates in above ground biomass, however less energy is allocated to the roots since nutrients is abundant. This leads to a lower biomass in the vegetation below ground which destabilizes the banks of

2831-563: A well-mixed water column and the disappearance of the vertical salinity gradient . The freshwater-seawater boundary is eliminated due to the intense turbulent mixing and eddy effects . The lower reaches of Delaware Bay and the Raritan River in New Jersey are examples of vertically homogeneous estuaries. Inverse estuaries occur in dry climates where evaporation greatly exceeds the inflow of freshwater. A salinity maximum zone

2980-436: A wholly marine embayment to any of the other estuary types. The most important variable characteristics of estuary water are the concentration of dissolved oxygen, salinity and sediment load. There is extreme spatial variability in salinity, with a range of near-zero at the tidal limit of tributary rivers to 3.4% at the estuary mouth. At any one point, the salinity will vary considerably over time and seasons, making it

3129-477: A wide effect on the surrounding water bodies.  In turn, this can decrease fishing industry sales in one area and across the country. Production in 2016 from recreational and commercial fishing contributes billions of dollars to the United States' gross domestic product (GDP). A decrease in production within this industry can affect any of the 1.7 million people the fishing industry employs yearly across

3278-418: Is 4 to 8 feet (1.2 to 2.4 m) deep at various times of year, and has an area of 18 acres (7.3 ha). The lake is used for recreational fishing, as it includes species such as largemouth bass , black crappie , brown bullhead , bluegill , pumpkinseed , golden shiner , common carp , white sucker , and yellow perch . It is fed by Tibbetts Brook , a stream originating in Yonkers, which runs through

3427-455: Is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides . The effects of tides on estuaries can show nonlinear effects on the movement of water which can have important impacts on the ecosystem and waterflow. The seawater entering the estuary is diluted by the fresh water flowing from rivers and streams. The pattern of dilution varies between different estuaries and depends on

3576-513: Is derived from the Latin word aestuarium meaning tidal inlet of the sea, which in itself is derived from the term aestus , meaning tide. There have been many definitions proposed to describe an estuary. The most widely accepted definition is: "a semi-enclosed coastal body of water, which has a free connection with the open sea, and within which seawater is measurably diluted with freshwater derived from land drainage". However, this definition excludes

3725-411: Is formed, and both riverine and oceanic water flow close to the surface towards this zone. This water is pushed downward and spreads along the bottom in both the seaward and landward direction. Examples of an inverse estuary are Spencer Gulf , South Australia, Saloum River and Casamance River , Senegal. Estuary type varies dramatically depending on freshwater input, and is capable of changing from

3874-638: Is known as the Peach War . This forced the settlers, including van der Donck's widow, to flee to Manhattan. Following the takeover of the New Netherland colony by the British in 1664, the claim to the estate was awarded to Hugh O'Neale, the new husband of van der Donck's widow. Because the O'Neales lived far away from the land, the claim was awarded to O'Neale's brother-in-law and van der Donck's widow's brother, Elias Doughty, who proceeded to sell off

4023-566: Is less restricted, and there is a slow but steady exchange of water between the estuary and the ocean. Fjord-type estuaries can be found along the coasts of Alaska , the Puget Sound region of western Washington state , British Columbia , eastern Canada, Greenland , Iceland , New Zealand, and Norway. These estuaries are formed by subsidence or land cut off from the ocean by land movement associated with faulting , volcanoes , and landslides . Inundation from eustatic sea-level rise during

4172-698: Is the Colorado River Delta in Mexico, historically covered with marshlands and forests, but now essentially a salt flat. Van Cortlandt Park Van Cortlandt Park is a 1,146-acre (464 ha) park located in the borough of the Bronx in New York City . Owned by the New York City Department of Parks and Recreation , it is managed with assistance from the Van Cortlandt Park Alliance. The park,

4321-560: Is the third-largest park in New York City, behind the Staten Island Greenbelt (1,778 acres (720 ha)) and Pelham Bay Park (2,772 acres (1,122 ha)). It has numerous attractions and features that are both recreational and educational. The different parts of Van Cortlandt Park have a varied geology. The Northwest Woods and Old Croton Aqueduct Trailway have a steep terrain dotted with Fordham gneiss ,

4470-646: Is the whitefish species from the European Alps . Eutrophication reduced the oxygen levels in their habitats so greatly that whitefish eggs could not survive, causing local extinctions. However, some animals, such as carnivorous fish, tend to do well in nutrient-enriched environments and can benefit from eutrophication. This can be seen in populations of bass or pikes. Eutrophication can affect many marine habitats which can lead to economic consequences. The commercial fishing industry relies upon estuaries for approximately 68 percent of their catch by value because of

4619-533: The Bronx River Parkway , and Pelham Parkway between Jerome Avenue and Pelham Bay Park. By the 1960s, large portions of the park, such as Tibbetts Brook, were being polluted by human activity; in addition, the brook now flowed into the Broadway sewer at the south end of Van Cortlandt Lake. Pollution from upstream and the highways, and spillover of chemicals used in the golf course, killed fish in

4768-546: The Croton Water Filtration Plant , a drinking water treatment facility, under the park's Mosholu Golf Course. Plant operations began in 2015. The plant was needed in order to filter contaminants from urban runoff pollution in the Croton River watershed and protect the public from Giardia and Cryptosporidium , microorganisms which can cause serious health problems. The Croton plant

4917-748: The Holocene Epoch has also contributed to the formation of these estuaries. There are only a small number of tectonically produced estuaries; one example is the San Francisco Bay , which was formed by the crustal movements of the San Andreas Fault system causing the inundation of the lower reaches of the Sacramento and San Joaquin rivers . In this type of estuary, river output greatly exceeds marine input and tidal effects have minor importance. Freshwater floats on top of

5066-473: The Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays , harbors , lagoons , inlets , or sounds , although some of these water bodies do not strictly meet

5215-610: The Mandovi estuary in Goa during the monsoon period. As tidal forcing increases, river output becomes less than the marine input. Here, current induced turbulence causes mixing of the whole water column such that salinity varies more longitudinally rather than vertically, leading to a moderately stratified condition. Examples include the Chesapeake Bay and Narragansett Bay . Tidal mixing forces exceed river output, resulting in

5364-640: The Mid-Atlantic coast, and Galveston Bay and Tampa Bay along the Gulf Coast . Bar-built estuaries are found in a place where the deposition of sediment has kept pace with rising sea levels so that the estuaries are shallow and separated from the sea by sand spits or barrier islands. They are relatively common in tropical and subtropical locations. These estuaries are semi-isolated from ocean waters by barrier beaches ( barrier islands and barrier spits ). Formation of barrier beaches partially encloses

5513-622: The New York Philharmonic and Metropolitan Opera performed in the field during the summer. However, it too had deteriorated because of intensive use: the grounds' topsoil had eroded away and the sidewalks started to buckle. In 1978, the Perrier Company donated a fitness trail consisting of 12 exercise machines to the park; there were originally supposed to be 18 machines, but the extra six machines were deemed unnecessary. Two shuffleboard courts were also installed in

5662-674: The Severn Estuary in the United Kingdom and the Ems Dollard along the Dutch-German border. The width-to-depth ratio of these estuaries is typically large, appearing wedge-shaped (in cross-section) in the inner part and broadening and deepening seaward. Water depths rarely exceed 30 m (100 ft). Examples of this type of estuary in the U.S. are the Hudson River , Chesapeake Bay , and Delaware Bay along

5811-597: The Unami language . The strip of land on the Hudson River's east bank, between the current-day Spuyten Duyvil Creek and Yonkers , was sold to the Dutch West India Company in the early 17th century. Adriaen van der Donck , a Dutch settler, bought the land from the company in 1646. Van der Donck also paid the Indian chief Tacharew, whose tribe used to live on the land, as a friendly gesture. He named

5960-489: The University of Amsterdam , goes into great detail about all the various translations for "Spuyten Duyvil" which have been mooted over the years. Rentenaar concludes that "Duyvil" means "devil", either literally or in a transferred sense, but he could not determine what the intended meaning of "Spuyten" was because of the many variants that have been used throughout history. The local Lenape Native Americans referred to

6109-478: The black-tailed godwit , rely on estuaries. Two of the main challenges of estuarine life are the variability in salinity and sedimentation . Many species of fish and invertebrates have various methods to control or conform to the shifts in salt concentrations and are termed osmoconformers and osmoregulators . Many animals also burrow to avoid predation and to live in a more stable sedimental environment. However, large numbers of bacteria are found within

6258-650: The Croton River upstate to the New York Public Library Main Branch and Bryant Park in midtown Manhattan . The project was built by 3,000–4,000 laborers who completed the entire aqueduct in five years. The aqueduct's builders constructed a gatehouse within the present-day park to provide access to the aqueduct's interior. The old aqueduct was supplemented by the New Croton Aqueduct in 1890, which also ran through

6407-589: The Croton Water Filtration Plant project, the New York City Department of Environmental Protection was given $ 200 million to mitigate the effects of constructing the plant. A feasibility study in 2009 found that a bridge near the location of 233rd Street was the most feasible, and would connect the two sections of the trail. This bridge was deferred over lack of funding in 2014 before planning resumed in 2015. The John Kieran Nature Trail (1.25 miles (2.01 km), easy), which connects to

6854-539: The Mosholu Golf Course, was also built using Croton mitigation funds. As part of the "Van Cortlandt Park Master Plan 2034", critical ecological elements of the park, such as the forest, the rural landscape, and Tibbetts Brook, would be restored, and the brook would be diverted. As of March 2014 when the report was written, the lack of natural drainage points within Van Cortlandt Park led to

7003-540: The New York City Department of Parks and Recreation mentioned that the lake had probably not been cleaned since the mid-18th century, and now contained a layer of "refuse and vegetation on top, and an ooze two to three feet deep on the bottom," with qualities more like a "semi-bog." Cleaning of the lake started in 1903. The lake's original earthen dam was removed, the lake was emptied, and 30,000 cubic yards (23,000 m ) of deposits were dredged from

7152-579: The Parade Grounds the same year, but went unused because of a lack of playing equipment. In response to studies and accounts that showed the bad condition of the lake, the state restored the fish population of the lake in 1978. In 1977, the Bronx Borough Board created a special committee to oversee and develop plans for improving Van Cortlandt Park. The Friends of Van Cortlandt Park soon came up with its own suggestions to improve

7301-581: The Parks Department proposed to dredge the swamp and create a lake in its stead, but despite this plan receiving $ 70,000 in funding in 1906, it was deemed "not feasible" to drain the swamp directly into the Broadway sewer. Another plan to remove the swamps in the park's southwest was approved in 1904. The plan was to build an athletic field in the southwest swamp's place, but all swamp-infill proposals for this sector were rejected in 1917. By 1922, there were 23 acres (9.3 ha) of swampland left in

7450-546: The Putnam Branch tracks, and a fungicide with 8.5% cadmium content that was being sprayed on the golf course. A year later, a private landscaping firm estimated that it would cost $ 4–7 million to restore the Van Cortlandt Lake. By this point, the lake was so dirty that a small boat could not float on it, even though the lake was 15 feet (4.6 m) deep. Catfish were the only fish that could survive in

7599-549: The Putnam Trail, opened in 1987 and is named after local writer and naturalist John Kieran. The path features 13 stone pillars, each made of a different variety of stone, that were tested for the facade of Grand Central Terminal during the terminal's construction . The variety eventually chosen was Indiana limestone because it was cheap. The trail hugs the edge of the Van Cortlandt Lake and Tibbetts Brook marsh. The John Muir Trail (1.5 miles (2.4 km), moderate)

7748-400: The United States. Estuaries are incredibly dynamic systems, where temperature, salinity, turbidity, depth and flow all change daily in response to the tides. This dynamism makes estuaries highly productive habitats, but also make it difficult for many species to survive year-round. As a result, estuaries large and small experience strong seasonal variation in their fish communities. In winter,

7897-541: The Van Cortlandt Course during winters. Also in the late 1960s, the city decided to build a series of public pools on the site of the Colonial Garden, consisting of a diving, a swimming, and a wading pool. Construction on the $ 1.5 million pools started in early 1969 and was completed by 1970. Because of the swampy nature of the ground underneath it, the pools soon began to crackle and set. By 1979,

8046-529: The Van Cortlandt Golf Course compounded the lake's dirty condition, and by 1912, the lake and brook contained significant sedimentation. Nearby residents also disliked the wetlands near the lake, as they could be used to breed malaria -borne mosquitoes, and were thus seen as "unsightly and unsanitary." In 1896, they proposed to fill the wetlands in, and the infill proposal was funded by the New York City Board of Estimate in 1899. Subsequently,

8195-567: The Van Cortlandt House on the former Tippett property, but died before its completion. The Van Cortlandts did not primarily live in that house, instead staying in Manhattan most of the time. A family burial ground was created in 1749, later to be known as "Vault Hill." Frederick, who was buried in Vault Hill, had willed the massive home and surrounding lands to his son, James Van Cortlandt (1727–1787). The Van Cortlandt family land

8344-659: The Van Cortlandt House on the property, but died before its completion. Later, the land was used during the Revolutionary War when the Stockbridge militia was destroyed by the Queen's Rangers . In 1888, the family property was sold to the City of New York and made into a public parkland. The Van Cortlandt House, later designated as a historic landmark, was converted into a public museum, and new paths were created across

8493-513: The above definition of an estuary and could be fully saline. Many estuaries suffer degeneration from a variety of factors including soil erosion , deforestation , overgrazing , overfishing and the filling of wetlands. Eutrophication may lead to excessive nutrients from sewage and animal wastes; pollutants including heavy metals , polychlorinated biphenyls , radionuclides and hydrocarbons from sewage inputs; and diking or damming for flood control or water diversion. The word "estuary"

8642-625: The barrier down. In 1669 Verveelen transplanted his ferry to the northern tip of Marble Hill, at today's Broadway and West 231st Street. In 1693 Frederick Philipse , a Dutch nobleman who had sworn allegiance to the Crown upon the British takeover of Dutch New Netherlands , built the King's Bridge at Marble Hill near what is now West 230th Street in the Bronx. Originally a merchant in New Amsterdam , Philipse had purchased vast landholdings in what

8791-452: The bottom where they are harmless. Historically the oysters filtered the estuary's entire water volume of excess nutrients every three or four days. Today that process takes almost a year, and sediment, nutrients, and algae can cause problems in local waters. Some major rivers that run through deserts historically had vast, expansive estuaries that have been reduced to a fraction of their former size, because of dams and diversions. One example

8940-494: The city border. The new course, which started at the original polo fields, did not conflict with either of the golf courses. In 1922, there was a proposal to acquire land for the future Saw Mill River Parkway , which would connect the park to 424 acres (172 ha) of open space in Westchester when completed. Through the 1930s, the New York City Department of Parks and Recreation kept adding new recreational facilities in

9089-654: The city purchase the property. Around the same time, New York Herald editor John Mullaly pushed for the creation of parks in New York City, particularly lauding the Van Cortlandt and Pell families' properties in the western and eastern Bronx respectively. He formed the New York Park Association in November 1881. There were objections to the system, which would apparently be too far from Manhattan, in addition to precluding development on

9238-493: The city to propose alternate sites for the plant. The plant was built 160 feet (49 m) below the Mosholu Golf Course, at a cost of $ 3.2 billion. To lessen the disruption caused by the plant's construction, in 2010 the city used mitigation funds from the construction budget to restore the Van Cortlandt Park Parade Ground. The Sachkerah Woods Playground, located at the park's southeast corner near

9387-463: The city's approval, particularly overgrown areas of the property were made passable. Wide walking paths were built over original walkways, including the thin paths that led to the Van Cortlandt family cemetery, high on the nearby bluffs. "Certain lands" around the house were then filled in for the purpose of creating a "Colonial Garden," which was proposed in 1897. During excavation of the grounds, Indian artifacts and graves were found, corresponding to

9536-717: The city's third-largest, was named for the Van Cortlandt family , which was prominent in the area during the Dutch and English colonial periods. Van Cortlandt Park's sports facilities include golf courses and several miles of paths for running, as well as facilities for baseball , basketball , cricket , cross-country running , football , horseback riding , lacrosse , rugby , soccer , softball , swimming , tennis and track and field . The park also contains five major hiking trails and other walking trails. Its natural features include Tibbetts Brook; Van Cortlandt Lake ,

9685-433: The course, and golfers would wear long-sleeved shirts to ward off against the city's insufficient mosquito repellents. Homeless squatters moved into the park, while courses fell into disrepair, replaced by dirt tracks and "huts and forts" built by neighborhood kids. In 1985, the city licensed control of the courses to Los Angeles -based American Golf Corporation for 60 years, leading to their restoration. Other parts of

9834-480: The creek at 230th Street was destroyed in the late 1920s. In 1919, New York State passed a bill in order to straighten the western end of the creek feeding into the Hudson. At the time, the creek was diverted south to avoid a peninsula that housed the Johnson Iron Works foundry. The foundry held out until 1923 when it vacated the premises, and in 1927 was awarded $ 3.28 million in compensation, just over

9983-422: The creek at modern West 230th Street. The brook currently ends above ground within Van Cortlandt Park , emptying into the Harlem River system at the Wards Island Water Pollution Control Plant via underground sewers. During the 17th century, the only mode of transportation across the Harlem River was by ferry from the east end of 125th Street . The ferry was established in 1667 and operated by Johannes Verveelen,

10132-402: The creek by several names. The first was Shorakapok or Shorackhappok , translated as “the sitting down place” or “the place between the ridges”. A second term, spelled various ways including Paparinemo or Papiriniman , was shared with a triangular island formed by the junction of the creek and Tibbetts Brook in today's Kingsbridge neighborhood. The word has been translated as "place where

10281-472: The creek has been subsumed by the modern ship canal. The Bronx neighborhood of Spuyten Duyvil lies to the north of the estuary creek, and the adjacent Manhattan neighborhood of Marble Hill lies to the north of the Ship Canal. The earliest use of the name "Spuyten Duyvil" was in 1653, in a document from Dutch landowner Adriaen van der Donck to the Dutch West India Company . It may be literally translated as "Spouting Devil" or Spuitende Duivel in Dutch ;

10430-409: The dissolved oxygen from the water; thus hypoxic or anoxic zones can develop. Nitrogen is often the lead cause of eutrophication in estuaries in temperate zones. During a eutrophication event, biogeochemical feedback decreases the amount of available silica . These feedbacks also increase the supply of nitrogen and phosphorus, creating conditions where harmful algal blooms can persist. Given

10579-401: The effects of modifying the estuarine circulation. Fjord -type estuaries are formed in deeply eroded valleys formed by glaciers . These U-shaped estuaries typically have steep sides, rock bottoms, and underwater sills contoured by glacial movement. The estuary is shallowest at its mouth, where terminal glacial moraines or rock bars form sills that restrict water flow. In the upper reaches of

10728-601: The estuary impacted by human activities, and over time may shift the basic composition of the ecosystem, and the reversible or irreversible changes in the abiotic and biotic parts of the systems from the bottom up. For example, Chinese and Russian industrial pollution, such as phenols and heavy metals, has devastated fish stocks in the Amur River and damaged its estuary soil. Estuaries tend to be naturally eutrophic because land runoff discharges nutrients into estuaries. With human activities, land run-off also now includes

10877-424: The estuary, the depth can exceed 300 m (1,000 ft). The width-to-depth ratio is generally small. In estuaries with very shallow sills, tidal oscillations only affect the water down to the depth of the sill, and the waters deeper than that may remain stagnant for a very long time, so there is only an occasional exchange of the deep water of the estuary with the ocean. If the sill depth is deep, water circulation

11026-776: The estuary, with only narrow inlets allowing contact with the ocean waters. Bar-built estuaries typically develop on gently sloping plains located along tectonically stable edges of continents and marginal sea coasts. They are extensive along the Atlantic and Gulf coasts of the U.S. in areas with active coastal deposition of sediments and where tidal ranges are less than 4 m (13 ft). The barrier beaches that enclose bar-built estuaries have been developed in several ways: Fjords were formed where Pleistocene glaciers deepened and widened existing river valleys so that they become U-shaped in cross-sections. At their mouths there are typically rocks, bars or sills of glacial deposits , which have

11175-501: The fact that Luther R. Marsh, vice president of the New York Park Association, owned land near Van Cortlandt Park in particular. Opponents argued that building a park system would divert funds from more important infrastructure like schools and docks; that everyone in the city, instead of just the property owners near the proposed park, was required to pay taxes to pay for the parks' construction; and that since Marsh

11324-530: The first recorded people to inhabit in the area now referred to as Van Cortlandt Park. They settled in the area around the 14th or 15th centuries. The Lenapes used the geographic features of the area to support their community; for instance, they used the Tibbetts Brook , Spuyten Duyvil Creek , or Hudson River for fishing, and flatland areas for farming. They formed a village named Keskeskick, whose name roughly translates to "sharp grass or sedge marsh" in

11473-609: The fish community is dominated by hardy marine residents, and in summer a variety of marine and anadromous fishes move into and out of estuaries, capitalizing on their high productivity. Estuaries provide a critical habitat to a variety of species that rely on estuaries for life-cycle completion. Pacific Herring ( Clupea pallasii ) are known to lay their eggs in estuaries and bays, surfperch give birth in estuaries, juvenile flatfish and rockfish migrate to estuaries to rear, and anadromous salmonids and lampreys use estuaries as migration corridors. Also, migratory bird populations, such as

11622-432: The flooding of recreational areas within the park during heavy rains. The park's paths would also be restored with the addition of three new pedestrian bridges; a playground; four activity centers, of which two would be outdoors and two would be indoors; a skate park; an athletic field; and three basketball courts built within the park. "Comfort stations" and food concessions would also be added. The Van Cortlandt Golf Course

11771-408: The following June. Besides plants, the garden had rustic wooden bridges and wooden stairs and a "handsome fountain and central court." A "Shakespeare Garden" was also opened that year, with a grand stairway leading down to it. The next year, park officials realized that the Colonial Garden's construction was of poor quality and hard to cultivate. The garden had to be raised 3.5 feet (1.1 m), and

11920-525: The forests. The stock of younger, replacement trees in the old-growth forest had relatively little diversity compared to other natural forests. In 1979, New York City Councilwoman June Eisland released a report on Van Cortlandt Park. The report noted that pollutants from the Major Deegan Expressway were entering Van Cortlandt Lake, and that the park ecosystem was also being harmed by inadequate drainage, soil sterilants that were used on

12069-454: The former Van Cortlandt Park station can be seen along the trail. As part of the park's 2034 master plan, NYC Parks undertook a project to pave the entirety of the trail through Van Cortlandt Park as well as a short extension to the south, making it usable for both pedestrians and bicyclists. A construction contract for the paving project was awarded in October 2018 to Grace Industries, and it

12218-449: The garden looked just fine. Under threat of tearing the garden down, the city had to find money to fill and drain the ground. The rebuilding contract was awarded in 1909 and completed by 1911. Various adjustments were made over succeeding years. A network of roads through the park was built soon after, allowing the construction of picnic areas and hiking trails as well as making the forests more accessible to visitors. A stone memorial

12367-400: The great biodiversity of this ecosystem. During an algal bloom , fishermen have noticed a significant increase in the quantity of fish. A sudden increase in primary productivity causes spikes in fish populations which leads to more oxygen being utilized. It is the continued deoxygenation of the water that then causes a decline in fish populations. These effects can begin in estuaries and have

12516-469: The house to deceive the British into thinking that his troops were still on the grounds. Washington used the house one final time in 1783 after the Treaty of Paris . The British had just withdrawn their troops from Manhattan, and Washington and George Clinton were getting ready to enter the island, stopping over at the house before doing so. In the 1830s, officials in a rapidly expanding New York City saw

12665-420: The impacts do not end there. Plant death alters the entire food web structure which can result in the death of animals within the afflicted biome . Estuaries are hotspots for biodiversity , containing a majority of commercial fish catch, making the impacts of eutrophication that much greater within estuaries. Some specific estuarine animals feel the effects of eutrophication more strongly than others. One example

12814-476: The lake and forest, which had been overtaken by invasive species introduced during highway construction. Since then, there have been seven plans for restoring natural elements of the park, as well as three plans for park restoration. Gradual improvements began taking place in the late 1980s, including the addition of new pathways, signage, and security, as well as the restoration of playgrounds and other recreational facilities. In January 1988, NYC Parks conducted

12963-415: The lake bed. A new 2,270-foot (690 m) retaining wall was then erected along the lake's eastern shore, and a new dam was installed to reform the lake and to allow future cleaning of the lake without having to dredge it. After the opening of an overflow drain in 1911–1912, which connected to the sewer under Broadway completed in 1907, Tibbetts Brook was directed into the new sewer, The construction of

13112-753: The lake was used by up to 3,000 skaters on weekdays and 10,000 on weekends. The ice-skating house, shared with the golf course, was added in 1902. By 1935, the lake was used by approximately 20,000 skaters daily. There are several old-growth forests with tree species and genera such as black oak , hickory , beech , cherry birch , sweetgum , red maple , and tuliptree . The forests also contain wild turkeys , red-tailed hawks , great horned owls , bats , Eastern chipmunks , Eastern gray squirrels , groundhogs , gypsy moths , Eastern cottontail rabbits , striped skunks , North American raccoons , Virginia opossums , white-tailed deer and Eastern coyotes . In addition, over 130 species of butterflies can be found in

13261-525: The lake water. The city of Yonkers eventually attributed the cause of the Van Cortlandt Lake's pollution to four storm sewers that were found to be illegally connected to Tibbetts Brook upstream. The utter disrepair in the park prompted some informal rules at the park's golf courses. For instance, the Los Angeles Times noted that "a player was allowed to drop his ball a club length away if it rolled up against an abandoned auto, or, in one case,

13410-432: The lake's surface area was being lost to sedimentation every year. In addition, an algal bloom caused the lake to be in a low-oxygen condition, endangering plants and animals in and around the lake. "Unpleasant odors" in the summer also reduced recreational opportunities on the lake, and these conditions combined made it virtually impossible to come into contact with the lake's water without getting sick. By 1976, there

13559-496: The lake. This problem was first noticed in May 1961 when thousands of dead bass , pickerel , catfish , perch , and carp floated up at the edge of the lake. The mass-death of fish was blamed on siltation, Three years later, fish were still being killed by siltation. City investigators took water samples from the lake and found that they contained large amounts of weeds and sediment . About 22,000 square feet (2,000 m ) of

13708-525: The land " Colen Donck " and built a house upon the land. The house was built between current-day Van Cortlandt Lake and Broadway . It faced south, probably because this was the location of a natural marshland. What is now the parade ground was used by van der Donck for farming. Van der Donck died in 1655. That year the Munsee bands that lived in the lower Hudson River valley briefly occupied New Amsterdam and attacked Pavonia and Staten Island during what

13857-497: The land part of the Philipsburg Manor , which extended from Spuyten Duyvil Creek to the Croton River in modern Westchester County . Philipse's wife died, and he remarried Olof Stevense Van Cortlandt's daughter, herself a widow. Philipse's daughter Eva later married Jacobus Van Cortlandt , who was Mrs. Philipse's brother. The land that Van Cortlandt Park now occupies was acquired by Van Cortlandt from Philipse in

14006-515: The largest freshwater lake in the Bronx; old-growth forests; and outcrops of Fordham gneiss and Inwood marble . Contained within the park is the Van Cortlandt House , the oldest known surviving house in the Bronx, and the Van Cortlandt Golf Course, the oldest public golf course in the country. The land that Van Cortlandt Park now occupies was purchased by Jacobus Van Cortlandt from John Barrett around 1691. His son Frederick built

14155-400: The locker rooms were heavily vandalized and the diving pool had been closed. The city's fiscal crisis in the 1970s caused the rest of the park to fall into disrepair. A dearth of funds exacerbated the pollution of the park. Hands-on education programs at the park were reduced to passive observations of flora and fauna. Elsewhere in the park, excessive foot traffic was eroding the soil in

14304-525: The many chemicals used as fertilizers in agriculture as well as waste from livestock and humans. Excess oxygen-depleting chemicals in the water can lead to hypoxia and the creation of dead zones . This can result in reductions in water quality, fish, and other animal populations. Overfishing also occurs. Chesapeake Bay once had a flourishing oyster population that has been almost wiped out by overfishing. Oysters filter these pollutants, and either eat them or shape them into small packets that are deposited on

14453-422: The marine environment, such as plastics , pesticides , furans , dioxins , phenols and heavy metals . Such toxins can accumulate in the tissues of many species of aquatic life in a process called bioaccumulation . They also accumulate in benthic environments, such as estuaries and bay muds : a geological record of human activities of the last century. The elemental composition of biofilm reflect areas of

14602-575: The marsh causing increased rates of erosion . A similar phenomenon occurs in mangrove swamps , which are another potential ecosystem in estuaries. An increase in nitrogen causes an increase in shoot growth and a decrease in root growth. Weaker root systems cause a mangrove tree to be less resilient in seasons of drought, which can lead to the death of the mangrove. This shift in above ground and below ground biomass caused by eutrophication could hindered plant success in these ecosystems. Across all biomes, eutrophication often results in plant death but

14751-501: The mid-to-late 1690s. In 1699, Van Cortlandt dammed Tibbetts Brook in order to power a sawmill (and later, a gristmill , ), creating Van Cortlandt Lake as a mill pond in the process. In 1732, Van Cortlandt acquired an additional parcel from the Tippett family. The estate was then passed on to Jacobus's son Frederick Van Cortlandt (1699–1749) and family in 1739; it was once a vast grain plantation. In 1748, Frederick built

14900-402: The new creek. In 1914 the original creekbed was filled in with rock from the excavation of Grand Central Terminal 's foundation during its construction ; and the temporary island, comprising present-day Marble Hill , became physically attached to the Bronx, though it remained politically part of the borough of Manhattan, as it is today. The bridge carrying Broadway over the former alignment of

15049-649: The new park was being planned, the New York City & Northern Railroad, later the New York and Putnam Railroad , was built through the center of the park. It had two stops in the Bronx: one inside the park, and another to the south at Kingsbridge . South of Kingsbridge, the railroad merged with the present-day Hudson Line of the Metro-North Railroad . The tracks were used for passenger traffic until 1958, and by freight trains until 1981. A shuttle train

15198-440: The now off-balance nitrogen cycle , estuaries can be driven to phosphorus limitation instead of nitrogen limitation. Estuaries can be severely impacted by an unbalanced phosphorus cycle, as phosphorus interacts with nitrogen and silica availability. With an abundance of nutrients in the ecosystem, plants and algae overgrow and eventually decompose, which produce a significant amount of carbon dioxide. While releasing CO 2 into

15347-560: The old aqueduct. The trail features vestiges of an old, disused brick tunnel that brought water to Manhattan, as well as a gatehouse for the aqueduct. Within the park, the Old Croton Aqueduct trail borders Mosholu Golf Center and Driving Range, as well as the Allen Shandler Recreation Area. Its southern end is cut off by the Major Deegan Expressway in the southwestern end of the park. As part of

15496-449: The old right-of-way becoming Tibbett Avenue. A bridge opened over the former Marble Hill alignment of the creek in 1900, carrying Broadway. The bridge's superstructure was demolished shortly afterward, with the construction of the IRT subway above Broadway in 1904. The effect of channeling through what had been 222nd and 223rd streets was to physically isolate Marble Hill on the Bronx side of

15645-460: The old village of Keskeskick. The nine-hole Van Cortlandt Golf Course opened on July 6, 1895, as the country's first and oldest public golf course. The 2,561-yard (2,342 m) course comprised current holes 1, 2, 3, 6, 7, 12, 13, and 14. The first eight holes were easier and less than 200 yards (180 m) apart, but the last one had a fairway 700 yards (640 m) in length. The ninth hole, which spanned two stone walls and two small brooks,

15794-504: The park also fell into disrepair, such as Vault Hill, whose headstones and crypts were vandalized in the 1960s. As early as 1962, a New York Times reader wrote of vandalism on Vault Hill. A lack of annual maintenance of the park's jogging tracks and bridle paths had caused them to erode and become overgrown at some places. In 1978–1979, NYC Parks performed a wholesale renovation of the park's eroded and dilapidated bridle paths and jogging tracks. The Parade Ground remained popular, and

15943-405: The park into six pieces and demolished most of the remaining marsh in the park. This construction also induced siltation of the brook, leading to further creation of marshes. Moses also made improvements to the park itself, building new walkways, paving dirt roads, creating playgrounds, and installing lights. Baseball, soccer, and cricket fields were added in 1938. The Van Cortlandt Stadium

16092-460: The park since 1875, when records were first kept. Amphibians present include American bullfrogs , red-backed salamanders , and spring peepers . Also present in and around the park's waterways and wetlands are common snapping turtles and Eastern painted turtles , as well as red-eared sliders that were introduced to the region. There are five major hiking trails in the park. The Putnam Trail (1.5 miles (2.4 km), easy), runs north through

16241-462: The park to fall into disrepair. Gradual improvements began taking place from the late 1980s on including the addition of new pathways, signage, and security. In 2014, the "Van Cortlandt Park Master Plan 2034" was published. The forest in what is now Van Cortlandt Park has been around for 17,000 years, since the end of the Wisconsin glaciation . The Wiechquaskeck , a Wappinger people, were among

16390-507: The park's baseball diamonds. The park's recreational facilities were quite popular, with more than 10,000 people using them on a busy day. However, during and following World War I, the Parade Ground was used for war training. Until 1926, the baseball fields did not contain backstops , and had to be vacated by July 4 of every year, so the National Guard could use the field. The 6.2-mile (10.0 km) cross-country running course

16539-406: The park, and two airplane pilots were fined in 1947 for unauthorized airplane landings. Around 1939, the old aqueduct, which was now a popular hiking trail, started becoming a popular route with cyclists. Soon after, there was a proposal to redevelop the trail as a bike path. This proposal never came to fruition, although in the mid-1970s, the city built a separate bike path along Mosholu Parkway,

16688-486: The park, and the Parks Department hoped to convert parts of it for some athletic purpose, but this required the New York Central Railroad to raise one of its bridges first so the swampland could be accessed. However, there are no records of that bridge being raised or of the swamp being converted. In its early years, the lake was used for boating , canoeing , curling , and ice skating . By 1899,

16837-549: The park, the width of the parkways ' lanes was reduced. Tibbetts Brook was dredged and landscaped in 1938 to accommodate construction. Such construction continued until 1955, during which the Major Deegan Expressway (current Interstate 87 ) was also built, bisecting the Mosholu Parkway. This conflicted with Moses's plans for the park as a "rural oasis", as highway construction ultimately separated

16986-414: The park. In 1937, it was noted that the marshlands had fauna such as red-winged blackbirds , yellowthroats , green bottle flies , beetles , dragonflies , tadpoles , herons , kingfishers , and ospreys . Its flora included cattail , skunk cabbage , and moss . Its avian population during the winters has exceeded that of either Central or Prospect Parks; a total of 301 bird species have been seen in

17135-441: The park. After the parcourse for the parade grounds was approved in 1978, the New York City Department of Parks promised to cooperate on the Van Cortlandt Park improvement plans. The 1979 Eisland plan also detailed suggestions for park improvements. This culminated in the 1980 appointment of a park coordinator who would start devising details of a "master plan" for the park. In 1985, a study recommended ecological restoration of

17284-501: The park. The Colonial and Shakespeare Gardens had a combined 250,000 flowers by 1931, but both were demolished by the end of the decade due to bad drainage. In 1934, Robert Moses became the New York City Parks Commissioner, and during his 16-year tenure as commissioner, altered almost every aspect of the park. His job partially entailed balancing the needs of area residents, whose numbers had grown in

17433-509: The park. The Old Croton Aqueduct was in use until 1955, though the part that ran through the park was closed down in 1897 after the new aqueduct was connected to the Jerome Park Reservoir . In 1876, Frederick Law Olmsted was hired to survey the Bronx and map out streets based on the local geography. Olmsted noted the natural beauty of the Van Cortlandt estate, comparing it to Central Park which he designed, and recommended

17582-428: The parks would appreciate greatly over time; that the commission had only chosen property that could easily be converted into a park; and that Pelham Bay Park would soon be annexed to the city. Ultimately, the parks were established despite the objections of major figures like Mayors William Russell Grace and Abram Hewitt ; Comptroller Edward V. Loew; and Assemblymen Henry Bergh and Theodore Roosevelt. In 1880 while

17731-554: The past decade, with transit users who traveled to the park from the north and south. Moses's development plans in the 1930s called for the construction of the Henry Hudson Parkway and Mosholu Parkway to bisect Van Cortlandt Park and meet at a trumpet interchange about half a mile north of the center, merging into the Saw Mill River Parkway. Due to objections over the construction of roads inside

17880-497: The portions of the property. In 1668, a portion of the land was sold to William Betts, an English turner , and his son-in-law George Tippett, whom Tibbetts Brook would later be named for. This property included the modern park parade grounds. Next, Doughty sold a 2,000-acre (810 ha) tract of land, including the current site of the Van Cortlandt House , to Frederick Philipse , Thomas Delavall , and Thomas Lewis. Philipse bought out Delavall's and Lewis's land shares, making

18029-581: The property to make it more passable. In the 1930s, the Robert Moses –directed construction of the Henry Hudson Parkway and Mosholu Parkway fragmented Van Cortlandt Park into its six discontinuous pieces. The last remaining freshwater marsh in New York State , Tibbetts Brook , was dredged and landscaped to accommodate construction, causing large-scale ecological disruption within the park. The 1975 New York City fiscal crisis caused much of

18178-427: The seawater in a layer that gradually thins as it moves seaward. The denser seawater moves landward along the bottom of the estuary, forming a wedge-shaped layer that is thinner as it approaches land. As a velocity difference develops between the two layers, shear forces generate internal waves at the interface, mixing the seawater upward with the freshwater. An examples of a salt wedge estuary is Mississippi River and

18327-411: The sediment which has a very high oxygen demand. This reduces the levels of oxygen within the sediment often resulting in partially anoxic conditions, which can be further exacerbated by limited water flow. Phytoplankton are key primary producers in estuaries. They move with the water bodies and can be flushed in and out with the tides . Their productivity is largely dependent upon the turbidity of

18476-622: The site. However, newspapers and prominent lobbyists, who supported such a park system, were able to petition the bill into the New York State Senate , and later, the New York State Assembly (the legislature's lower house ). In June 1884, Governor Grover Cleveland signed the New Parks Act into law, authorizing the creation of the park system. Legal disputes carried on for years, exacerbated by

18625-486: The southwest of the Van Cortlandt Station was converted to a lake. An "outlet sewer" under Broadway was built in 1907. From 1903 to 1911, NYC Parks cleaned the 13-foot-deep (4.0 m) Van Cortlandt Lake, removed the original earthen dam , and emptied the lake in order to dredge the lake bed to a lower depth. A new dam was installed to reform the lake. The former marshland was filled in. During

18774-513: The stream is shut" or to "parcel out" or "divide". A third name, Muscoota , was also used. Spuyten Duyvil Creek was originally a narrow tidal strait connecting the Hudson River to the west and the headwaters of the Harlem River to the east, both of which were fed by the waters of Tibbetts Brook flowing south from the Bronx. When the Dutch settlers arrived they found its tidal waters turbulent and difficult to handle. Though its tides raced, there

18923-418: The tight turn up and around Marble Hill. The Harlem Canal Company (then stylized as the "Harlaem Canal Company") was founded in 1826, but did not make any progress towards building a canal. A second company also failed to complete the project. In 1863 the Hudson and Harlem River Canal Company was created, and began the final plans for the canal. The U.S. Congress broke the logjam in 1873 by appropriating money for

19072-456: The volume of freshwater, the tidal range, and the extent of evaporation of the water in the estuary. Drowned river valleys are also known as coastal plain estuaries. In places where the sea level is rising relative to the land, sea water progressively penetrates into river valleys and the topography of the estuary remains similar to that of a river valley. This is the most common type of estuary in temperate climates. Well-studied estuaries include

19221-429: The war, however. Later, the grounds were used by Patriot militia leaders Comte de Rochambeau , Marquis de Lafayette , and George Washington . The house itself was Washington's headquarters after his troops were defeated in the 1776 Battle of Long Island . That same year, Augustus Van Cortlandt hid city records under Vault Hill to protect them during the war, turning them over to the new American government after

19370-430: The war. It was in "Indian Field," at the present-day intersection of Van Cortlandt Park East and 233rd Street, that the Stockbridge militia was destroyed by the Queen's Rangers , and 38 Indians from the militia were killed in 1778. In 1781, Washington returned to the house to strategize with Rochambeau while their troops waited outside on what is now the Parade Ground and Vault Hill. He later lit campfires outside

19519-453: The water and atmosphere, these organisms are also intaking all or nearly all of the available oxygen creating a hypoxic environment and unbalanced oxygen cycle . The excess carbon in the form of CO 2 can lead to low pH levels and ocean acidification , which is more harmful for vulnerable coastal regions like estuaries. Eutrophication has been seen to negatively impact many plant communities in estuarine ecosystems . Salt marshes are

19668-835: The water. The main phytoplankton present are diatoms and dinoflagellates which are abundant in the sediment. A primary source of food for many organisms on estuaries, including bacteria , is detritus from the settlement of the sedimentation. Of the thirty-two largest cities in the world in the early 1990s, twenty-two were located on estuaries. As ecosystems, estuaries are under threat from human activities such as pollution and overfishing . They are also threatened by sewage, coastal settlement, land clearance and much more. Estuaries are affected by events far upstream, and concentrate materials such as pollutants and sediments. Land run-off and industrial, agricultural, and domestic waste enter rivers and are discharged into estuaries. Contaminants can be introduced which do not disintegrate rapidly in

19817-584: The woods to the east of this lawn and west of Van Cortlandt Lake, through the golf course and along Tibbetts Brook and the former New York and Putnam Railroad line into Yonkers, where it connects to Westchester County's paved South County Trailway . Previously unpaved, the Putnam Trail underwent a reconstruction project starting in August 2019 and was reopened in October 2020 as a paved pedestrian and bicycle path. The rails themselves were overrun with weeds, but they were no longer usable by trains. The remains of

19966-401: Was a moratorium on all boating activities on the lake. The Van Cortlandt Golf Course was used as a ski slope during the winters starting in 1961, and up to 3,000 visitors would use the slopes each weekend. By 1964, with the use of artificial snow, it was also possible to ski during warmer days. The seasonal ski slope was closed in the late 1960s when the city decided to allow golfers to use

20115-479: Was added in 1939 on the site of a former swamp, and a pool followed in 1970. Moses also landscaped the areas near the Woodlawn and 242nd Street subway stations to attract park visitors from other neighborhoods. During his tenure as Parks Commissioner, Moses took aggressive approach to preserving the park's quality. For instance, six mothers were issued court summonses in 1942 after letting their children dig in

20264-436: Was among the country's hardest holes. Four years after the course opened, the city hired Tom Bendelow , nicknamed the "Johnny Appleseed of Golf", to expand it to 18 holes. The course added a clubhouse in 1902, which also doubled as an ice-skating house. At first, the park was sparsely used for sports. In 1899, there were 10, 7, and 5 permits issued for lawn tennis, baseball, and football, respectively. The Parade Ground

20413-463: Was built after a lawsuit was filed in 1997 against the city by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Justice and the State of New York . The city settled the suit and a consent decree was issued with the condition that the city would build the plant by 2006. The project experienced delays and ballooning costs due to objections from the local community, which required

20562-481: Was completed in October 2020. The Old Croton Aqueduct Trailway (1.1 miles (1.8 km), easy/moderate), was created in 1968 when the New York State Office of Parks, Recreation and Historic Preservation had bought a 26.2-mile (42.2 km) stretch of the Old Croton Aqueduct, for use as a walking trail. It starts in Van Cortlandt Park as a grass-and-dirt trail and runs north along the route of

20711-546: Was converted to recreational use starting in 1902, when the National Guard added fields for polo . In 1907, due to overcrowding, Dr. William Hornaday transferred 15 of the Bronx Zoo 's then-rare bison to the Parade Ground, where they stayed until they were shipped to prairie land in Oklahoma later that year. The Colonial Garden, designed by landscape architect Samuel Parsons , started construction in 1902 and opened

20860-594: Was inaugurated in 1914. The track started out as a flat path, became hilly, turned onto a "little spell of road work," went into the forest, and crossed a water before turning back. A year later, it hosted the Metropolitan Association of the Amateur Athletic Union's Junior and Senior Cross Country championships. A modified 3.1-mile (5.0 km) cross-country course opened on November 5, 1921, with runners simply changing direction at

21009-633: Was later established across the span. The new bridge proceeded to take much of the traffic away from the King's Bridge. The Free Bridge was destroyed during the American Revolution . Following the war, Philipse Manor was forfeited to the state legislature, after which the King's Bridge was free.
