Question: How many meters is the Riverbank State Park elevated above the largest river located in the state where the writer Amalie Schoppe died?

full_context: Document 1: 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.
Document 2: 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 3: 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 4: Frédéric Chopin: At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.
Document 5: 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 6: 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 7: 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 8: 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 9: 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 10: Caroline Rudolphi: Rudolphi moved her institute to Heidelberg in 1803 (in the newly formed Electorate of Baden), where she became socially involved with the circle of Romanticist intellectuals there (Achim von Arnim, Clemens Brentano, Sophie Mereau, Friedrich Creuzer Ludwig Tieck) and a close friend of the family of classicist Johann Heinrich Voß.
Document 11: Frédéric Chopin: In Paris, Chopin encountered artists and other distinguished figures, and found many opportunities to exercise his talents and achieve celebrity. During his years in Paris he was to become acquainted with, among many others, Hector Berlioz, Franz Liszt, Ferdinand Hiller, Heinrich Heine, Eugène Delacroix, and Alfred de Vigny. Chopin was also acquainted with the poet Adam Mickiewicz, principal of the Polish Literary Society, some of whose verses he set as songs.
Document 12: Jeanette Wohl: Jeanette Wohl (October 16, 1783, Frankfurt am Main – November 27, 1861, Paris) was a longtime friend and correspondent of Ludwig Börne. She inherited the rights to his literary works after his death and edited his works. She is buried at Père Lachaise Cemetery in Paris.
Document 13: 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 14: 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 15: Amalie Schoppe: Her friends included Rosa Maria Assing, Justinus Kerner and Adelbert von Chamisso, along with the young poet Friedrich Hebbel, whom she introduced to patrons and allowed to use her study. From 1827 to 1846 she edited the Pariser Modeblätter as well writing literary articles for it. She also wrote for several other magazines and from 1831 to 1839 edited the young peoples' magazine Iduna. From 1842 to 1845 she lived in Jena, before moving back to Hamburg and finally in 1851 to the United States of America with her son, where she died aged 66 in Schenectady, New York
