Glacial Lake Albany was a prehistoric North American proglacial lake that formed during the end of the Wisconsinan glaciation. [1] [2] It existed between 15,000 and 12,600 years ago [3] and was created when meltwater from a retreating glacier, along with water from rivers such as the Iromohawk, became ice dammed in the Hudson Valley. [1] [4] Organic materials in Lake Albany deposits have been carbon dated to approximately 11,700 years ago. [5] The lake spanned approximately 160 miles (260 km) from present-day Poughkeepsie to Glens Falls. [1] [3] [6]
Lake Albany drained about 10,500 years ago through the Hudson River due to post-glacial rebound. [1] [6] [7] When the lake drained it exposed the sandy and gravelly glaciolacustrine deposits left by the glacier, along a broad plain just west of Schenectady, where the Mohawk emptied into the lake. [8] Dune and deltaic sands, containing lenses of silty sand, silt and clay, [9] compose the topsoil which now underlies the Albany Pine Bush. [10] Beneath the surficial deposits are lake-bottom silt and clay, which overlie till and shale bedrock. [9] A small rill caused by the lake's drainage created Patroon Creek, Sand Creek, Lisha Kill, Shaker Creek, Delphus Kill and the Salt Kill in the town of Colonie, New York. [11]
Albany County is a county in the state of New York, United States. Its northern border is formed by the Mohawk River, at its confluence with the Hudson River, which is to the east. As of the 2020 United States Census, the population was 314,848. The county seat and largest city is Albany, which is also the state capital of New York. As originally established by the English government in the colonial era, Albany County had an indefinite amount of land, but has had an area of 530 square miles (1,400 km2) since March 3, 1888. The county is named for the Duke of York and of Albany, who became James II of England.
The Richelieu River is a river of Quebec, Canada, and a major right-bank tributary of the St. Lawrence River. It rises at Lake Champlain, from which it flows northward through Quebec and empties into the St. Lawrence. It was formerly known by the French as the Iroquois River and the Chambly River, and was named for Cardinal Richelieu, the powerful minister under Louis XIII.
A kame delta is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame deposits. Upon entering a proglacial lake at the end (terminus) of a glacier, the river/stream deposit these sediments. This landform can be observed after the glacier has melted and the delta's asymmetrical triangular shape is visible. Once the glacier melts, the edges of the delta may subside as ice under it melts. Glacial till is deposited on the lateral sides of the delta, as the glacier melts.
The Capital District, also known as the Capital Region, is the metropolitan area surrounding Albany, the capital of the U.S. state of New York. The Capital District was first settled by the Dutch in the early 17th century and came under English control in 1664. Albany has been the permanent capital of the state of New York since 1797. The Capital District is notable for many historical events that predate the independence of the United States, including the Albany Plan of Union and the Battles of Saratoga.
Lake Hitchcock was a glacial lake that formed approximately 15,000 years ago in the late Pleistocene epoch. After the Laurentide Ice Sheet retreated, glacial ice melt accumulated at the terminal moraine and blocked up the Connecticut River, creating the long, narrow lake. The lake existed for approximately 3,000 years, after which a combination of erosion and continuing geological changes likely caused it to drain. At its longest, Lake Hitchcock stretched from the moraine dam at present-day Rocky Hill, Connecticut, to St. Johnsbury, Vermont. Although the rift valley through which the river flows above Rocky Hill actually continues south to New Haven, on Long Island Sound, the obstructing moraine at Rocky Hill diverted the river southeast to its present mouth at Old Saybrook.
The Albany Pine Bush, referred to locally as the Pine Bush, is one of the largest inland pine barrens in the world. It is centrally located in New York's Capital District within Albany and Schenectady counties, between the cities of Albany and Schenectady. The Albany Pine Bush was formed thousands of years ago, following the drainage of Glacial Lake Albany.
Area codes 518 and 838 are telephone area codes in the North American Numbering Plan for eastern Upstate New York in the United States. 518 is one of the 86 original North American area codes created in 1947. Area code 838 was added to the 518 numbering plan area in 2017. The two area codes serve 24 counties and 1,200 ZIP Code areas in a numbering plan area (NPA) that extends from the eastern Mohawk Valley to the Vermont border, and from the Canada–US border to south of Albany. The bulk of the population is in the Capital District, the vicinity of the cities Albany, Schenectady, and Troy. Other cities in the NPA are Glens Falls, Plattsburgh, and Saratoga Springs. It includes the Upper Hudson Valley counties, Greene and Columbia counties, and some northern parts of Dutchess County.
Rome Sand Plains is a 15,000-acre (61 km2) pine barrens about five miles (8.0 km) west of the city center of Rome in Oneida County in central New York. It consists of a mosaic of sand dunes rising about 50 feet (15 m) above low peat bogs that lie between the dunes. The barrens are covered with mixed northern hardwood forests, meadows, and wetlands. About 4,000 acres (16 km2) are protected in conservation preserves. Pine barrens are typical of seacoasts; the Rome Sand Plains is one of only a handful of inland pine barrens remaining in the United States. A second inland pine barrens, the Albany Pine Bush, is also found in New York, located north and west of state's capital Albany.
Superior National Forest, part of the United States National Forest system, is located in the Arrowhead Region of the state of Minnesota between the Canada–United States border and the north shore of Lake Superior. The area is part of the greater Boundary Waters region along the border of Minnesota and the Canadian province of Ontario, a historic and important thoroughfare in the fur trading and exploring days of New France and British North America.
Rensselaer Lake is an artificial lake in Albany, New York, United States named for Major-General Stephen Van Rensselaer, last patroon of Rensselaerswyck. The lake was Albany's first municipally-owned source of water. It is part of a 57-acre (23 ha) park and the state's Albany Pine Bush Preserve. The lake and park have been under the purview of the Albany Water Authority since 2003.
Superficial deposits refer to geological deposits typically of Quaternary age for the Earth. These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine. All pre-Quaternary deposits are referred to as bedrock.
The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by three of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.
The neighborhoods of Albany, New York are listed below.
Patroon Creek is a stream in Albany County, New York, United States and is a tributary of the Hudson River which flows south to New York Harbor and the Atlantic Ocean. The creek's source is Rensselaer Lake in the western section of the city of Albany. Patroon Creek received its name from the patroon of Rensselaerswyck.
New England is a region in the North Eastern United States consisting of the states Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine. Most of New England consists geologically of volcanic island arcs that accreted onto the eastern edge of the Laurentian Craton in prehistoric times. Much of the bedrock found in New England is heavily metamorphosed due to the numerous mountain building events that occurred in the region. These events culminated in the formation of Pangaea; the coastline as it exists today was created by rifting during the Jurassic and Cretaceous periods. The most recent rock layers are glacial conglomerates.
Lake Vermont, also called Glacial Lake Vermont, was a temporary lake created by the retreating glaciers during the close of the last ice age. The lake once included land in the Canadian province of Quebec and the American states Vermont and New York. It was a geologic predecessor of Lake Champlain. Once the glacier retreated far enough north, it drained into Glacial Lake Candona, a geologic predecessor of the St. Lawrence River.
The Champlain Sea was a prehistoric inlet of the Atlantic Ocean into the North American continent, created by the retreating ice sheets during the closure of the last glacial period. The inlet once included lands in what are now the Canadian provinces of Quebec and Ontario, as well as parts of the American states of New York and Vermont. Today, the remains of the sea include the St. Lawrence Seaway, Lake Champlain, Lake of Two Mountains on the lower Ottawa River, the lower Saguenay River, as well as other lakes, islands and shores.
Lake Merrimack was a glacial lake that formed during the late Pleistocene epoch. After the Laurentide Ice Sheet retreated, glacial ice melt accumulated at the terminal moraine and blocked up the Merrimack River, creating the narrow lake. The lake extended from Manchester to Plymouth, New Hampshire. It is unknown when the lake was drained.
The geology of Rhode Island is based on nearly one billion year old igneous crystalline basement rocks formed as part of the microcontinent Avalonia that collided with the supercontinent Gondwana. The region experienced substantial folding associated with its landlocked position during the Alleghanian orogeny mountain building event. The region accumulated sedimentary rocks, including small deposits of coal. The region was covered with thick Atlantic Coastal Plain sediments, with the erosion of the Appalachians and the creation of the Atlantic Ocean throughout the past 200 million years. These surficial sediments and soils were substantially reworked by the Pleistocene glaciations. The state's geology is part of the broader geology of New England.
