England, from where its earliest European settlers came.

Suffolk County was an original county of New York State, one of twelve created in 1683. Its boundaries were substantially the same as at present, with only minor changes in the boundary with its western neighbor, which was originally Queens County but since 1899 has been Nassau County. However, as eastern Suffolk County has become more suburbanized there have been efforts to split the east end of the county off into a new county, called Peconic County.
The first nomadic hunters came here in the last glacial period following caribou herds when Long Island and the mainland of Connecticut were separated by only low-lying marshland. This area is now covered by Long Island Sound. The first known Europeans to sight Long Island were with Verrazano, who sailed along the south shore in 1524. In 1614 Adrian Block, a Dutch explorer, first touched the land here when he went ashore at Montauk and met local Native Americans.
As reported by the Census Bureau, the county has a total area of 2,373 square miles (6,146 km2), of which, 912
square miles (2,363 km2) of it is land and 1,461 square miles (3,784 km2) of it (61.56%) is water. The highest
elevation in the county, and on Long Island as a whole, is Jayne's Hill in West Hills, at 401 feet (122 m) above sea
level.
Suffolk County occupies the easternmost portion of Long Island, in the southeastern portion of New York State. The
eastern end of the county splits into two peninsulas, known as the North Fork and the South Fork. The county is
surrounded by water on three sides, including the Atlantic Ocean and the Long Island Sound. The eastern end contains
large bays. Suffolk County is divided into 10 towns: Babylon, Brookhaven, East Hampton, Huntington, Islip,
Riverhead, Shelter Island, Smithtown, Southampton, and Southold. Also part of the county, but not considered parts
of the above towns, are the Poospatuck and Shinnecock Indian reservations. Poospatuck is enclaved within Brookhaven
in the Mastic CDP, and Shinnecock is enclaved within Southampton, adjacent to Southampton village, Tuckahoe, and
Shinnecock Hills.
Major facilities include Brookhaven National Laboratory in Upton and Plum Island Animal Disease Center on Plum
Island. Several airports serve commuters and business travelers, most notably Long Island MacArthur Airport in
Islip, Republic Airport in East Farmingdale and Francis S. Gabreski Airport in Westhampton Beach.
