Lake Vermont
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 geographical predecessor of Lake Champlain. Once the glacier retreated far enough north, it drained into Glacial Lake Candona, the geologic predecessor of the St. Lawrence River. At one time, Lake Vermont may have reached nearly as far south as to what is now Albany, New York. The surface of the lake was about above present day Lake Champlain, and was up to deep. The lake contained muddy water, and the sediment of Lake Vermont contains silt/clay varves, with silt being deposited during summer and clay during the less-energetic flow of winter. The Laurentide Ice Sheet retreated north of what is now Burlington, Vermont, about 13,500 years ago, marking the beginning of Lake Vermont. The ice damming the water at the north ...

Glacial Lakes Albany, Champlain, Hitchcock, Winsooski, & Merrimack
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a Greenhouse and icehouse Earth, greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the m ...

Champlain Sea
The Champlain Sea (french: Mer de Champlain) 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. 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 the 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 gradually rose again, in the process known as isostatic rebound, the sea coast gradually retreated to its current location. The sea lasted from about 13,000 years ago to about ...

Natural History Of Quebec
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

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.

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).

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, 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 clay in the ...

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.

Warwick, Quebec
Warwick is a small town north east of Montreal, located in Arthabaska county, Quebec, Canada. The town was incorporated in 1861 and named after a city of the same name in England. Up until 2014 the town hosted Quebec's annual summer cheese festival, which showcases many of the locally produced artisanal cheeses. In 2014 the festival was moved to Victoriaville. Warwick also claims to be one of the possible birthplaces of poutine (fries with gravy and cheese curds). It is an industrial centre, with factories for agricultural machinery, washing-machines, overalls, cheese-boxes, and doors. Warwick is located on Route 116.

Glaciers
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
