Question: How many meters is Riverbank State Park elevated above the largest river in the state known as New Amsterdam prior to capture by the English?

full_context: Document 1: Hudson River: The Hudson River is a 315 - mile (507 km) river that flows from north to south primarily through eastern New York in the United States. The river originates in the Adirondack Mountains of Upstate New York, flows through the Hudson Valley, and eventually drains into the Atlantic Ocean, between New York City and Jersey City. The river serves as a political boundary between the states of New Jersey and New York, and further north between New York counties. The lower half of the river is a tidal estuary occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Tidal waters influence the Hudson's flow from as far north as Troy.
Document 2: Dutch colonization of the Americas: In 1664, an English naval expedition ordered by Prince James, Duke of York and of Albany (later King James II & VII) sailed in the harbor at New Amsterdam, threatening to attack. Being greatly outnumbered, Director - General Peter Stuyvesant surrendered after negotiating favorable articles of capitulation. The Province then took a new name, New York (from James's English title). Fort Orange was renamed Fort Albany (from James's Scottish title). The region between the lower Hudson and the Delaware was deeded to proprietors and called New Jersey.
Document 3: Appalachian Trail: New York's 88.4 miles (142.3 km) of trail contain very little elevation change compared to other states. From south to north, the trail summits many small mountains under 1,400 feet (430 m) in elevation, its highest point in New York being Prospect Rock at 1,433 feet (437 m), and only 3,000 feet (910 m) from the border with New Jersey. The trail continues north, climbing near Fitzgerald Falls, passing through Sterling Forest, and then entering Harriman State Park and Bear Mountain State Park. The lowest point on the entire Appalachian Trail is in the Bear Mountain Zoo 124 feet (38 m). It crosses the Hudson River on the Bear Mountain Bridge. It then passes through Fahnestock State Park, and continues northeast and crosses the Metro - North Railroad's Harlem Line. This track crossing is the site of the only train station along the trail's length. It enters Connecticut via the Pawling Nature Reserve. The section of the trail that passes through Harriman and Bear Mountain State Parks is the oldest section of the trail, completed in 1923. A portion of this section was paved by 700 volunteers with 800 granite - slab steps followed by over a mile of walkway supported by stone crib walls with boulders lining the path. The project took four years, cost roughly $1 million, and was officially opened in June 2010. The project was done by the New York -- New Jersey Trail Conference. The New York -- New Jersey Trail Conference maintains and updates the Appalachian Trail in New York.
Document 4: Hoosic River: The Hoosic River, also known as the Hoosac, the Hoosick (primarily in New York) and the Hoosuck (mostly archaic), is a tributary of the Hudson River in the northeastern United States. The different spellings are the result of varying transliterations of the river's original Algonquian name. It can be translated either as "the beyond place" (as in beyond, or east of, the Hudson) or as "the stony place" (perhaps because the river's stony bottom is usually exposed except in spring, or perhaps because local soils are so stony).
Document 5: New York City: During the Wisconsinan glaciation, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth. The ice sheet scraped away large amounts of soil, leaving the bedrock that serves as the geologic foundation for much of New York City today. Later on, the ice sheet would help split apart what are now Long Island and Staten Island.
Document 6: New York City: In 1664, Peter Stuyvesant, the Director-General of the colony of New Netherland, surrendered New Amsterdam to the English without bloodshed. The English promptly renamed the fledgling city "New York" after the Duke of York (later King James II).
Document 7: The Bronx: The Bronx's highest elevation at 280 feet (85 m) is in the northwest corner, west of Van Cortlandt Park and in the Chapel Farm area near the Riverdale Country School. The opposite (southeastern) side of the Bronx has four large low peninsulas or "necks" of low-lying land that jut into the waters of the East River and were once salt marsh: Hunt's Point, Clason's Point, Screvin's Neck and Throg's Neck. Further up the coastline, Rodman's Neck lies between Pelham Bay Park in the northeast and City Island. The Bronx's irregular shoreline extends for 75 square miles (194 km2).
Document 8: History of New York City (prehistory–1664): The history of New York City has been influenced by the prehistoric geological formation during the last glacial period of the territory that is today New York City. The area was long inhabited by the Lenape; after initial European exploration in the 16th century, the Dutch established New Amsterdam in 1626. In 1664, the English conquered the area and renamed it New York.
Document 9: New York City: Gateway National Recreation Area contains over 26,000 acres (10,521.83 ha) in total, most of it surrounded by New York City, including the Jamaica Bay Wildlife Refuge in Brooklyn and Queens, over 9,000 acres (36 km2) of salt marsh, islands, and water, including most of Jamaica Bay. Also in Queens, the park includes a significant portion of the western Rockaway Peninsula, most notably Jacob Riis Park and Fort Tilden. In Staten Island, the park includes Fort Wadsworth, with historic pre-Civil War era Battery Weed and Fort Tompkins, and Great Kills Park, with beaches, trails, and a marina.
Document 10: New York City: New York City has over 28,000 acres (110 km2) of municipal parkland and 14 miles (23 km) of public beaches. Parks in New York City include Central Park, Prospect Park, Flushing Meadows–Corona Park, Forest Park, and Washington Square Park. The largest municipal park in the city is Pelham Bay Park with 2,700 acres (1,093 ha).
Document 11: Saint Lawrence River: The Saint Lawrence River (French: Fleuve Saint - Laurent; Tuscarora: Kahnawáʼkye; Mohawk: Kaniatarowanenneh, meaning ``big waterway '') is a large river in the middle latitudes of North America. The Saint Lawrence River flows in a roughly north - easterly direction, connecting the Great Lakes with the Atlantic Ocean and forming the primary drainage outflow of the Great Lakes Basin. It traverses the Canadian provinces of Quebec and Ontario, and is part of the international boundary between Ontario, Canada, and the U.S. state of New York. This river also provides the basis of the commercial Saint Lawrence Seaway.
Document 12: New York City: New York City is situated in the Northeastern United States, in southeastern New York State, approximately halfway between Washington, D.C. and Boston. The location at the mouth of the Hudson River, which feeds into a naturally sheltered harbor and then into the Atlantic Ocean, has helped the city grow in significance as a trading port. Most of New York City is built on the three islands of Long Island, Manhattan, and Staten Island.
Document 13: New Amsterdam: New Amsterdam was renamed New York on September 8, 1664, in honor of the Duke of York (later James II of England), in whose name the English had captured it. After the Second Anglo - Dutch War of 1665 -- 1667, England and the United Provinces of the Netherlands agreed to the status quo in the Treaty of Breda. The English kept the island of Manhattan, the Dutch giving up their claim to the town and the rest of the colony, while the English formally abandoned Surinam in South America, and the island of Run in the East Indies to the Dutch, confirming their control of the valuable Spice Islands. Today much of what was once New Amsterdam is New York City.
Document 14: New Amsterdam: On August 27, 1664, while England and the Dutch Republic were at peace, four English frigates sailed into New Amsterdam's harbor and demanded New Netherland's surrender, whereupon New Netherland was provisionally ceded by Stuyvesant. On September 6, Stuyvesant sent lawyer Johannes De Decker and five other delegates to sign the official Articles of Capitulation. This was swiftly followed by the Second Anglo - Dutch War, between England and the Dutch Republic. In June 1665, New Amsterdam was reincorporated under English law as New York City, named after the Duke of York (later King James II). He was the brother of the English King Charles II, who had been granted the lands.
Document 15: New York City: There are seven state parks within the confines of New York City, including Clay Pit Ponds State Park Preserve, a natural area which includes extensive riding trails, and Riverbank State Park, a 28-acre (110,000 m2) facility that rises 69 feet (21 m) over the Hudson River.
