The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides.
The Mohawk River [TieonontatátieKanien'ké:ha for "a river flowing through a mountain"] is a 149-mile-long (240 km) river in the U.S. state of New York. It is the largest tributary of the Hudson River. The Mohawk flows into the Hudson in Cohoes, New York, a few miles north of the city of Albany. The river is named for the Mohawk Nation of the Iroquois Confederacy. It is a major waterway in north-central New York. The largest tributary, the Schoharie Creek, accounts for over one quarter (26.83%) of the Mohawk River's watershed. Another main tributary is the West Canada Creek, which makes up for 16.33% of the Mohawk's watershed.
The Catskill Mountains, also known as the Catskills, are a physiographic province of the larger Appalachian Mountains, located in southeastern New York. As a cultural and geographic region, the Catskills are generally defined as those areas close to or within the borders of the Catskill Park, a 700,000-acre (2,800 km2) forest preserve protected from many forms of development under New York state law.
The Beaver Kill, sometimes written as the Beaverkill or Beaverkill River, is a tributary of the East Branch Delaware River, a main tributary of the Delaware River, approximately 44 miles (71 km) long, in the U.S. state of New York. The kill drains a 300-square-mile (780 km2) area of the Catskill Mountains and has long been celebrated as one of the most famous trout streams in the United States. Its preservation helped establish many of the basic conservation principles of rivers in the United States.
The Neversink River is a 55-mile-long (89 km) tributary of the Delaware River in southeastern New York in the United States. The name of the river comes from the corruption of an Algonquian language phrase meaning "mad river."
Rondout Creek is a 63.3-mile-long (101.9 km) tributary of the Hudson River in Ulster and Sullivan counties, New York, United States. It rises on Rocky Mountain in the eastern Catskills, flows south into Rondout Reservoir, part of New York City's water supply network, then into the valley between the Catskills and the Shawangunk Ridge, where it goes over High Falls and finally out to the Hudson at Kingston, receiving along the way the Wallkill River.
North–South Lake is an 1,100-acre (4.4 km²) state campground in the Catskill Forest Preserve near Palenville, New York operated by the New York State Department of Environmental Conservation near the site of the historic Catskill Mountain House overlooking the Hudson River. The escarpment on which the lakes are located is at 2,250 feet, 1,700 feet above the valley floor, providing a view of five states in clear weather.
Esopus Creek is a 65.4-mile-long (105.3 km) tributary of the Hudson River that drains the east-central Catskill Mountains in the U.S. state of New York. From its source at Winnisook Lake on the slopes of Slide Mountain, the Catskills' highest peak, it flows across Ulster County to the Hudson at Saugerties. Many tributaries extend its watershed into neighboring Greene County and a small portion of Delaware County. Midway along its length, it is impounded at Olive Bridge to create Ashokan Reservoir, the first of several built in the Catskills as part of New York City's water supply system. Its own flow is supplemented 13 miles (21 km) above the reservoir by the Shandaken Tunnel, which carries water from the city's Schoharie Reservoir into the creek.
Kaaterskill High Peak is one of the Catskill Mountains, located in the Town of Hunter in Greene County, New York, United States. It was once believed to be the highest peak in the entire range, but its summit, at 3,655 feet in elevation, places it only 23rd among the Catskill High Peaks. It is, however, the fourth most prominent peak in the range. Due to its situation as the easternmost High Peak, its summit is just outside the watersheds of New York City's reservoirs in the region.
Kaaterskill Falls is a two-stage waterfall on Spruce Creek in the eastern Catskill Mountains of New York, between the hamlets of Haines Falls and Palenville in Greene County. The two cascades total 260 feet in height, making Kaaterskill Falls one of the highest waterfalls in New York, and one of the Eastern United States' tallest waterfalls.
New York State Route 23A (NY 23A) is an east–west state highway in Greene County, New York, in the United States. It serves as a 34.56-mile (55.62 km) alternate route of NY 23 through the northern Catskill Mountains. The route passes several of the Catskill High Peaks, including Hunter Mountain, before dropping into the Hudson Valley via Kaaterskill Clove and ending at an intersection with U.S. Route 9W (US 9W) in the village of Catskill. NY 23A was assigned in the mid-1920s and has not been changed since. A portion of the route through Kaaterskill Clove was closed for several months in 2006 after landslides triggered by heavy rains damaged the route.
The geography of New York (state) varies widely. 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.
The Catskill Escarpment, often referred to locally as just the Escarpment or the Great Wall of Manitou, and known as the Catskill Front to geologists, is the range forming the northeastern corner of the Catskill Mountains in Greene and Ulster counties in the U.S. state of New York. It rises very abruptly from the Hudson Valley to summits above 3,000 feet (910 m) in elevation, including three of the Catskill High Peaks, with almost no foothills. The plateau to the south and west averages 2,000 feet (610 m) above sea level.
Kaaterskill Clove is a deep gorge, or valley, in New York's eastern Catskill Mountains, lying just west of the village of Palenville and in Haines Falls. The clove was formed by Kaaterskill Creek, a tributary of Catskill Creek rising west of North Mountain, and is estimated by geologists to be as much as 1 million years old. Kaaterskill High Peak and Roundtop Mountain rise to the south of the gorge, while South Mountain is to its north. This makes the gorge as deep as 2,500 feet in places.
The Poesten Kill is a 26.2-mile-long (42.2 km) creek in upstate New York located entirely in Rensselaer County, which flows westerly from its source at Dyken Pond in the town of Berlin to its mouth at the Hudson River in the city of Troy. It has been used historically as a source of water for local inhabitants and farmers and became even more important as a source of water power during the Industrial Revolution, during which many mills and factories sprung up along its banks.
Catskill Creek is a 46.0-mile-long (74.0 km) tributary of the Hudson River that drains the northeastern Catskill Mountains of the U.S. State of New York. From its source at Franklinton Vlaie in Schoharie County it flows southeast through parts of Albany County and Greene County to its mouth at the village of Catskill on the Hudson River.
Kaaterskill Creek is a 25.9-mile-long (41.7 km) tributary of Catskill Creek in Greene and Ulster counties in New York. Via Catskill Creek, it is part of the Hudson River watershed.
The Verkeerder Kill, sometimes Verkeerderkill and locally shortened to Kaidy Kill is an 8-mile-long (13 km) stream in Ulster County, New York, United States. It rises on the Shawangunk Ridge, in the town of Wawarsing, and flows southwards through the town of Shawangunk, toward the Shawangunk Kill, itself a major tributary of the Wallkill River. Ultimately it is a part of the Hudson River's watershed.
