New York - Geography

Geography

New York covers 54,556 square miles (141,300 km2) and ranks as the 27th largest state by size. The Great Appalachian Valley dominates eastern New York, while Lake Champlain is the chief northern feature of the valley, which also includes the Hudson River flowing southward to the Atlantic Ocean. The rugged Adirondack Mountains, with vast tracts of wilderness, lie west of the valley.

Most of the southern part of the state is on the Allegheny Plateau, which rises from the southeast to the Catskill Mountains. The western section of the state is drained by the Allegheny River and rivers of the Susquehanna and Delaware systems. The Delaware River Basin Compact, signed in 1961 by New York, New Jersey, Pennsylvania, Delaware, and the federal government, regulates the utilization of water of the Delaware system. The highest elevation in New York is Mount Marcy in the Adirondacks.

New York's borders touch (clockwise from the west) two Great Lakes (Erie and Ontario, which are connected by the Niagara River); the provinces of Ontario and Quebec in Canada; Lake Champlain; three New England states (Vermont, Massachusetts, and Connecticut); the Atlantic Ocean, and two Mid-Atlantic States, New Jersey and Pennsylvania. In addition, Rhode Island shares a water border with New York. New York is the only state that touches both the Great Lakes and the Atlantic Ocean, and is the second-largest of the original Thirteen Colonies.

In contrast with New York City's urban atmosphere, the vast majority of the state is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is the largest state park in the United States. It is larger than the Yellowstone, Yosemite, Grand Canyon, Glacier and Olympic National Parks combined. New York established the first state park in the United States at Niagara Falls in 1885. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction.

The Hudson River begins at Lake Tear of the Clouds and flows south through the eastern part of the state without draining Lakes George or Champlain. Lake George empties at its north end into Lake Champlain, whose northern end extends into Canada, where it drains into the Richelieu and then the St. Lawrence Rivers. Four of New York City's five boroughs are on three islands at the mouth of the Hudson River: Manhattan Island; Staten Island; and Long Island, which contains Brooklyn and Queens on its western end.

Upstate and downstate are often used informally to distinguish New York City or its greater metropolitan area from the rest of New York State. The placement of a boundary between the two is a matter of great contention. Unofficial and loosely defined regions of Upstate New York include the Southern Tier, which often includes the counties along the border with Pennsylvania, and the North Country, which can mean anything from the strip along the Canadian border to everything north of the Mohawk River.
