Adirondack Park in the context of "Fulton Chain of Lakes"

Upstate New York is a geographic region of New York State that lies north and northwest of the New York City metropolitan area of downstate New York. Upstate includes the middle and upper Hudson Valley, the Capital District, the Mohawk Valley region, Central New York, the Southern Tier, the Finger Lakes region, Western New York, and the North Country. Major cities across upstate New York from east to west include the state capital of Albany, Utica, Binghamton, Syracuse, Rochester, and Buffalo.

Before the European colonization of the Americas, the region of upstate New York was populated by several Native American tribes. It was home to the Iroquois Confederacy, an indigenous confederation of six tribes, known as the Six Nations. Henry Hudson made the first recorded European exploration of the region in 1609, and the Dutch erected Fort Orange (present-day Albany) in 1624, which was the first permanent European settlement in New York. The region saw many battles during the American Revolutionary War, with the Iroquois split between supporters of the loyalists and supporters of the revolutionaries. After the war ended, the 1784 Treaty of Fort Stanwix kicked off a series of treaties and purchases that saw the Iroquois cede the vast majority of their land in upstate New York to the newly formed United States.

The geography of New York varies widely across the state. Most of New York is dominated by farms, forests, rivers, mountains, and lakes. New York's Adirondack Park is larger than any U.S. National Park in the contiguous United States. Niagara Falls, on the Niagara River as it flows from Lake Erie to Lake Ontario, is a popular attraction. The Hudson River begins near 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 River and then the St. Lawrence. Four of New York City's five boroughs are on the three islands at the mouth of the Hudson River: Manhattan Island, Staten Island, and Brooklyn and Queens on Long Island.

"Upstate" is a common term for New York counties north of suburban Westchester, Rockland and Dutchess counties. Upstate New York typically includes the Catskill Mountains or areas North of the Catskill Mountains, the Capital District, The Adirondacks, the Erie Canal, Lake Champlain, Otsego Lake, Oneida Lake; rivers such as the Delaware, Genesee, Mohawk, and Susquehanna. The highest elevation in New York is Mount Marcy of the Adirondack Mountains. New York is the 27th-largest state.

The North Country of Upstate New York is the northernmost region of the U.S. state of New York. It is bordered by Lake Champlain to the east and further east to the adjacent state of Vermont and the New England region; the Adirondack Mountains / Adirondack Park and the Upper Capital District with the state capital of Albany to the south; the Mohawk Valley region of New York to the southwest; the Canadian-American international border (with the Province of Ontario in Canada) to the north; and Lake Ontario, (the eastern-most of the Great Lakes) and the Saint Lawrence River / Saint Lawrence Seaway, and beyond the waters again to Ontario / Canada to the west. A mostly rural forested area, the North Country includes seven counties (or 14, according to another group) of the 62 in New York state. Fort Drum, a United States Army base, is also located in the North Country region in Jefferson County, near Watertown, as is the adjacent Adirondack Park of 6.1 million acres, established 1892 as the oldest state park in the nation, and preserved / operated by the Adirondack Park Agency and the New York State Department of Environmental Conservation. As of 2024, the population of the region was 420,311 (revised figure from the last 2020 United States census).

The term "North Country" was first widely popularized within New York by the 1900 novel Eben Holden by Irving Bacheller.

Mount Marcy is the highest point in the Adirondack Mountains and the U.S. state of New York, with an elevation of 5,343.1 feet (1,628.6 m). It is located in the town of Keene in Essex County. The mountain is in the heart of the High Peaks Wilderness Area in Adirondack Park. Like the surrounding Adirondack Mountains, Marcy was heavily affected by large glaciers during recent ice ages, which deposited boulders on the mountain slopes and carved valleys and depressions on the mountain. One such depression is today filled by Lake Tear of the Clouds, which is often cited as the highest source of the Hudson River. The majority of the mountain is covered by hardwood and spruce-fir forests, although the highest few hundred feet are above the tree line. The peak is dominated by rocky outcrops, lichens, and alpine plants. The mountain supports a diverse number of woodland mammals and birds.

Mount Marcy's stature and expansive views make it a popular destination for hikers, who crowd its summit in the summer months. Multiple approaches to the summit are available from the north and south, with the most popular route being the Van Hoevenberg Trail. The first recorded ascent of the mountain was made by a party led by Ebenezer Emmons on August 5, 1837, who named it after New York governor William L. Marcy. One of the mountain's most notable ascents was made in 1901, when Theodore Roosevelt climbed it with his family, and learned during his descent that William McKinley was dying and he was to become President of the United States.

Plattsburgh is a city in and the county seat of Clinton County, New York, United States, situated on the north-western shore of Lake Champlain. The population was 19,841 at the 2020 census. The population of the surrounding (and separately incorporated) Town of Plattsburgh was 11,886 as of the 2020 census, making the combined population of Plattsburgh to be 31,727. Plattsburgh lies just to the northeast of Adirondack Park, immediately outside of the park boundaries. It is the second largest community in the North Country region (after Watertown), and serves as the main commercial hub for the sparsely populated northern Adirondack Mountains. The land around Plattsburgh was previously inhabited by the Iroquois, Western Abenaki, Mohican, and Mohawk people. Samuel de Champlain was the first ever recorded European that sailed into Champlain Valley and later claimed the region as a part of New France in 1609.

Plattsburgh was the site of the amphibious Battle of Plattsburgh in the War of 1812, a key American victory that marked the end of hostilities in the Northern United States. It has been an important military outpost for much of its history, from hosting one of the largest Citizens' Military Training Camps prior to World War I, and Plattsburgh Air Force Base, the east coast center of operations for the Strategic Air Command during much of the Cold War period. The conversion of the base to a civilian airport in the 1990s resulted from the Base Realignment and Closure process during the wind down of the Cold War, and today it serves as a hub for economic development for the region. The city was named one of the Financial Times Top 10 Micro Cities of the Future several times.

The Catskill Park is the designation for a large area of eastern New York centered on the Catskill Mountains. Like Adirondack Park to the north, the area is unusual in the United States because, while the entire area is considered "parkland", as of 2005 about 54 percent of the land within the boundary consists of privately owned inholdings. Another 5 percent is owned by New York City to protect four of the city's reservoirs that either lie partially within the park or have watersheds encompassing parts of the park. The remaining 41 percent, or 287,500 acres (116,300 ha), is publicly owned by the state as part of the Forest Preserve.

Like Adirondack Park, the total acreage is defined by a Blue Line which encompasses all or part of four counties: Delaware, Greene, Sullivan, and Ulster, amounting to about 700,000 acres (280,000 ha; 2,800 km).

New York's Forest Preserve comprises almost all the lands owned by the state of New York within the Adirondack and Catskill parks. It is managed by the state Department of Environmental Conservation (DEC).

As of 2022, the Forest Preserve covers nearly 3 million acres (12,000 km), about 61% of all land managed by DEC. Around 2.7 million acres (11,000 km) are in the Adirondacks while 288,000 acres (1,170 km) are in the Catskills.

Newcomb is a town in Essex County, New York, United States. The population was 436 at the 2010 census.
