Champlain Valley
The Champlain Valley is a region of the United States around Lake Champlain in Vermont and New York extending north slightly into Quebec, Canada. It is part of the St. Lawrence River drainage basin, drained northward by the Richelieu River into the St. Lawrence at Sorel-Tracy, Quebec (northeast of Montreal). The Richelieu valley is not generally referred to as part of the Champlain Valley. The Champlain Lake Valley is the most heavily populated region in Vermont, broadly stretching eastward from the lake's shore to the base of the Green Mountains. The state's largest city, Burlington, is located on the lake, and the city's associated suburban communities encompass part of the central section of the valley. Beyond urbanized Chittenden County, however, the valley's landscape is primarily open pasture and row crops, making the Champlain Valley the most productive agricultural region of Vermont. The New York portion of the Champlain Valley includes the eastern portions of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Champlain River
The Champlain River is 66.7 km long flowing on the north shore of St. Lawrence river. This river flows between Saint-Maurice River and the Batiscan River watershed, in Les Chenaux Regional County Municipality, in administrative region of Mauricie, in the province of Quebec, Canada. Geography Champlain River is flowing almost at the boundary between the manors of Batiscan and Champlain. Champlain river flows from north to south to empty in the St. Lawrence river at Champlain village. Champlain River rises at an altitude of about 130 meters in wetlands located at the foot of the moraine of Saint-Narcisse.William Tellier, Mylène Valley, Isabelle Lavoie and Stéphane Campeau, ''Portrait du bassin versant de la rivière Champlain, Rapport déposé au Comité ZIP les Deux-Rive (Portrait of the watershed of the river Champlain, report tabled by Deux-Rives ZIP Committee)''.

Essex County, New York
Essex County is a county in the U.S. state of New York. As of the 2020 census, the population was 37,381. Its county seat is the hamlet of Elizabethtown. Its name is from the English county of Essex. Essex is one of only 2 counties that are entirely within the Adirondack Park, the other being Hamilton County. History When counties were established in the state of New York in 1683, the present Essex County was part of Albany County. This was an enormous county, including the northern part of New York state as well as all of the present state of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766, by the creation of Cumberland County, and further on March 16, 1770, by the creation of Gloucester County, both containing territory now in Vermont. On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name Albany County. One of the other pieces, Charlotte County, containe ...

Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; R. S. P. Beekes has suggested that a " Pre-Greek origin is probable". This stem is also the ancestor of the English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French , most other European languages (with words like "marmoreal") more closely resemble the original Ancient Greek. Physical origins Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valle ...

Saint Lawrence River
The St. Lawrence River (french: Fleuve Saint-Laurent, ) is a large river in the middle latitudes of North America. Its headwaters begin flowing from Lake Ontario in a (roughly) northeasterly direction, into the Gulf of St. Lawrence, connecting the American Great Lakes to the North Atlantic Ocean, and forming the primary drainage outflow of the Great Lakes Basin. The river traverses the Canadian provinces of Ontario and Quebec, as well as the U.S. state of New York, and demarcates part of the international boundary between Canada and the United States. It also provides the foundation for the commercial St. Lawrence Seaway. Names Originally known by a variety of names by local First Nations, the St. Lawrence became known in French as ''le fleuve Saint-Laurent'' (also spelled ''St-Laurent'') in 1604 by Samuel de Champlain. Opting for the ''grande riviere de sainct Laurens'' and ''fleuve sainct Laurens'' in his writings and on his maps, de Champlain supplanted previous Fre ...

Physiographic Regions Of The World
Physiographic regions of the world are a means of defining Earth's landforms into distinct regions, based upon the classic three-tiered approach by Nevin M. Fenneman in 1916, that separates landforms into physiographic divisions, physiographic provinces, and physiographic sections. Originally used in North America, the model became the basis for similar classifications of other continents, and was still considered valid . Physiography During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a contraction of "''physi''cal" and "ge''ography''", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. Some geomorphologists held to a geological basis for physiography and emphasized a concept of physiographic regions while a conflicting trend among geographers was to equate physiography with "pure morphology," se ...

Great Appalachian Valley
The Great Appalachian Valley, also called The Great Valley or Great Valley Region, is one of the major landform features of eastern North America. It is a gigantic trough—a chain of valley lowlands—and the central feature of the Appalachian Mountains system. The trough stretches about from Quebec in the north to Alabama in the south and has been an important north–south route of travel since prehistoric times. Geography Broadly defined, the Great Valley marks the eastern edge of the Ridge and Valley physiographic province. There are many regional names of the Great Valley, such as the Shenandoah Valley. From a large perspective the Great Valley can be divided into a ''northern section'' and a ''southern section''. Northern section In its ''northern section'', the Great Valley includes the Champlain Valley around Lake Champlain and the upper Richelieu River that drains it into the Saint Lawrence; the Hudson River Valley, Newburgh Valley, and Wallkill Valley; and the ...

Lake George (lake), New York
Lake George ( moh, Kaniá:taro’kte), nicknamed the ''Queen of American Lakes'', is a long, narrow oligotrophic lake located at the southeast base of the Adirondack Mountains, in the northeastern portion of the U.S. state of New York. It lies within the upper region of the Great Appalachian Valley and drains all the way northward into Lake Champlain and the St. Lawrence River drainage basin. The lake is situated along the historical natural ( Amerindian) path between the valleys of the Hudson and St. Lawrence Rivers, and so lies on the direct land route between Albany, New York, and Montreal, Quebec, Canada. The lake extends about on a north–south axis, is deep, and ranges from in width, presenting a significant barrier to east–west travel. Although the year-round population of the Lake George region is relatively small, the summertime population can swell to over 50,000 residents, many in the village of Lake George region at the southern end of the lake.

Ticonderoga, New York
Ticonderoga (, moh, Tekaniataró:ken) is a town in Essex County, New York, United States. The population was 5,042 at the 2010 census. The name comes from the Mohawk ''tekontaró:ken'', meaning "it is at the junction of two waterways". The Town of Ticonderoga is in the southeastern corner of the county and is south of Plattsburgh. History In the 17th century, French explorers such as Samuel de Champlain encountered the area. The town was on the direct route, utilizing rivers and two long lakes, between New York City to the south and the French settlement of Montreal to the north. The town was the setting for historic battles and maneuvers during both the French and Indian War and the American Revolutionary War. Fort Ticonderoga, constructed by the French, who called it ''Fort Carillon'', in the 1750s, marked the location of an important portage between the two lakes, George and Champlain. The Town of Ticonderoga was formed in 1804 from part of the town of Crown Point. By ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
