Long Island Information
Long Island, New York is the largest island adjoining the continental United States, extending approximately 118 miles east-northeast from the mouth of the Hudson River. It is separated from the mainland on the north by the Long Island Sound and bounded by the Atlantic Ocean on the south and east. Twenty miles at its widest point, Long Island is composed of low plateaus on the north, longitudinal ridges of glacial moraine through the central parts of the island, and gently sloping plains to the south. The East End of the island is made up of two forks. The North Fork is approximately 28 miles long, the southern - terminating at Montauk Point - is about 44 miles in length. Peconic and Gardiners Bays separate the two forks and are where Shelter Island and Gardiners Island are located.
Totaling 1,377 square miles of land area, Long Island New York is divided into four counties: Kings (Brooklyn), Queens, Nassau, and Suffolk. Suffolk is the easternmost and by far the largest of the four, covering an expanse of 911 square miles. Following Suffolk is Nassau with 287 square miles, Queens County with 109, and Kings with 70 square miles, the westernmost County. Kings and Queens Counties (Brooklyn and Queens) border each other and fall within the jurisdiction of New York City.
Many people in the New York metropolitan area (even those on the island in Queens and Brooklyn) use the term "Long Island" or "the island" to refer to Nassau and Suffolk counties only.
