Welcome to the Big Apple! The name Manhattan derives from the word Manna-hata, as written in the 1609 logbook of Robert Juet, an officer on Henry Hudson's yacht Halve Maen (Half Moon). A 1610 map depicts the name Manahata twice, on both the west and east sides of the Mauritius River (later named the Hudson River). The word "Manhattan" has been translated as "island of many hills" from the Lenape language. The Encyclopedia of New York City offers other derivations, including from the Munsee dialect of Lenape: manahachtanienk ("place of general inebriation"), manahatouh ("place where timber is procured for bows and arrows"), or menatay ("island"). Manhattan Island is bounded by the Hudson River to the west and the East River to the east. To the north, the Harlem River divides Manhattan from The Bronx and the mainland United States. Several small islands are also part of the borough of Manhattan, including Randall's Island, Ward's Island, and Roosevelt Island in the East River, and Governors Island and Liberty Island to the south in New York Harbor. Manhattan Island is 22.7 square miles (58.8 km²) in area, 13.4 miles (21.6 km) long and 2.3 miles (3.7 km) wide, at its widest (near 14th Street). New York County as a whole covers a total area of 33.77 square miles (87.46 km²), of which 22.96 square miles (59.47 km²) are land and 10.81 square miles (28.00 km²) are water. One Manhattan neighborhood is actually contiguous with The Bronx. Marble Hill at one time was part of Manhattan Island, but the Harlem River Ship Canal, dug in 1895 to improve navigation on the Harlem River, separated it from the remainder of Manhattan as an island between the Bronx and the remainder of Manhattan. Before World War I, the section of the original Harlem River channel separating Marble Hill from The Bronx was filled in, and Marble Hill became part of the mainland. Marble Hill is one example of how Manhattan's land has been considerably altered by human intervention. The borough has seen substantial land reclamation along its waterfronts since Dutch colonial times, and much of the natural variation in topography has been evened out. Manhattan has fixed vehicular connections with New Jersey to the west via the George Washington Bridge, Holland Tunnel and Lincoln Tunnel, and to three of the four other New York City boroughs—the Bronx to the northeast and Brooklyn and Queens on Long Island to the east and south. Its only direct connection with the fifth New York City borough is the Staten Island Ferry across New York Harbor, which is free of charge. The ferry terminal is located adjacent to Battery Park at its southern tip. It is possible to travel to Staten Island via Brooklyn, using the Verrazano-Narrows Bridge.
