Lake Stowe
Lake Stowe was a glacial lake that formed in Central Vermont approximately 15,000 years ago in the late Pleistocene epoch. After the Laurentide Ice Sheet retreated, glacial ice melt accumulated at the terminal moraine. The lake existed until the glacier had completely melted. Then it flowed out through the Lamoille River valley. The lake was named after Stowe, near where evidence of the lake was discovered.

Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as glacial striations, striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-blocked lake, moraine-dammed lake, other glacial lake, supraglacial lake, and subglacial lake.

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and Rock (geology), rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines are those formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French language, French , which in turn is derived from the Savoyard dialect, Savoyard Italian ('mound of e ...

Lamoille River
The Lamoille River is a river which runs through northern Vermont and drains into Lake Champlain. It is about in length, and has a drainage area of around . The river generally flows southwest, and then northwest, from the water divide of the Green Mountains. It is the namesake of Lamoille County, Vermont, through which it flows. The river was the basis of the name of the now-defunct Lamoille Valley Railroad Company, successor to the St. Johnsbury and Lamoille County Railroad. Legend has it that early French settlers named the river ''La Mouette,'' meaning "The Seagull". However, a cartographer forgot to cross the t's, which led people to begin calling it ''La Moulle''. Over time, this became ''Lamoille,'' elided in speaking. In July 2023, heavy rains caused flooding on the Lamoille River and on the nearby Winooski River and Missisquoi River The Missisquoi River is a transboundary river of the east shore of Lake Champlain (via Missisquoi Bay), approximately long, in no ...

Stowe, Vermont
Stowe is a town in Lamoille County, Vermont, United States. The population was 5,223 at the 2020 census. The town lies on Vermont Routes 108 and 100. It is nicknamed "The Ski Capital of the East" and is home to Stowe Mountain Resort, a ski facility with terrain on Mount Mansfield, the highest peak in Vermont, and Spruce Peak. History The indigenous people who lived in the area now called Vermont were primarily Abenaki, who spoke Algonquian. They were forced aside by strategies of displacement after primarily British settlers flooded into the area after the French and Indian War. There are no surviving names from the original language, which was most likely Mahican, an Algonquian dialect akin to Abenaki. Stowe was chartered on June 8, 1763, by Royal Governor Benning Wentworth of the Province of New Hampshire. Vermont became a U.S. state in 1791. Two years later more settlers arrived in Stowe. By the turn of the nineteenth century, the majority of the town's property had b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Champlain Sea
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, and the lower Saguenay River, as well as other lakes, islands and shores. Origins The mass of ice from the continental ice sheets had depressed the rock beneath it over millennia. At the end of the last glacial period, while the rock was still depressed, the Saint Lawrence and Ottawa River valleys, as well as modern Lake Champlain, at that time Lake Vermont, were below sea level and flooded with rising worldwide sea levels, once the ice no longer prevented the ocean from flowing into the region. As the land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Albany
Glacial Lake Albany was a prehistoric North American proglacial lake that formed during the end of the Wisconsinan glaciation. It existed between 15,000 and 12,600 years ago 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. Organic materials in Lake Albany deposits have been carbon dated to approximately 11,700 years ago.The lake spanned approximately from present-day Poughkeepsie to Glens Falls. Lake Albany drained about 10,500 years ago through the Hudson River due to post-glacial rebound. 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. Dune and deltaic sands, containing lenses of silty sand, silt and clay, compose the topsoil which now underlies the Albany Pine Bush. Beneath the surficial deposits are lake-bottom silt and clay, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Hitchcock
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, north to St. Johnsbury, Vermont (about ). 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. Lake Hitchcock is an important part of the geology of Connecticut. It experienced annual layering of sediments, or varves: silt and sand in the summertime (due to glacial meltwater) and ...

Lake Merrimack
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. Lake Hitchcock is an important part of the geology of New Hampshire. It experienced annual layering of sediments, or varves: silt and sand in the summertime (due to glacial meltwater) and clay in the wintertime (as the lake froze).

Former Lakes Of The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built unti ...
