Skenoh Island
Skenoh Island is located at the north end of Canandaigua Lake, near the city of Canandaigua, New York, United States. It is one of two islands in the 11 Finger Lakes.The other is Frontenac Island, in Cayuga Lake near the town of Union Springs. Frequently it is described as New York's smallest state park; however, while it is one of the state's smallest protected areas, it is not formally designated as a state park, but rather it is a "unique area" managed by the New York State Department of Environmental Conservation. The island was previously known as Squaw Island until October 2021, when the name was changed to avoid the ethnic slur ''squaw''. It formed from the alluvial deposits of nearby Sucker Brook. Limestone from the brook's bedrock dissolved in its waters forms rare lime carbonate oncolites, known locally as "water biscuits", on its shores. Rises in the lake level following the damming of Canandaigua Outlet have reduced the island to a small portion of its former land. T ...

Seneca Language
Seneca (; in Seneca, or ) is the language of the Seneca people, one of the Six Nations of the Iroquois League; it is an Iroquoian language, spoken at the time of contact in the western portion of New York. While the name ''Seneca'', attested as early as the seventeenth century, is of obscure origins, the endonym translates to "those of the big hill." About 10,000 Seneca live in the United States and Canada, primarily on reservations in western New York, with others living in Oklahoma and near Brantford, Ontario. As of 2013, an active language revitalization program is underway. Classification and history Seneca is an Iroquoian language spoken by the Seneca people, one of the members of the Iroquois Five (later, Six) Nations confederacy. It is most closely related to the other Five Nations Iroquoian languages, Cayuga, Onondaga, Oneida, and Mohawk (and among those, it is most closely related to Cayuga). Seneca is first attested in two damaged dictionaries produced by the Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Colonization Of The Americas
During the Age of Discovery, a large scale European colonization of the Americas took place between about 1492 and 1800. Although the Norse had explored and colonized areas of the North Atlantic, colonizing Greenland and creating a short term settlement near the northern tip of Newfoundland circa 1000 CE, the later and more well-known wave by the European powers is what formally constitutes as beginning of colonization, involving the continents of North America and South America. During this time, several empires from Europe—primarily Britain, France, Spain, Portugal, Russia, the Netherlands and Sweden—began to explore and claim the land, natural resources and human capital of the Americas, resulting in the displacement, disestablishment, enslavement, and in many cases, genocide of the indigenous peoples, and the establishment of several settler colonial states. Some formerly European settler colonies—including New Mexico, Alaska, the Prairies or northern Grea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandbar
In oceanography, geomorphology, and Earth science, geoscience, a shoal is a natural submerged ridge, bank (geography), bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared crest and trough, troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and ocea ...

Central New York
Central New York is the central region of New York State, including the following counties and cities: With a population of about 773,606 (2009) and an area of , the region includes the Syracuse metropolitan area. Definitions The New York State Department of Transportation's definition of the Central/Eastern region includes the counties of Albany, Broome, Chenango, Columbia, Cortland, Delaware, Fulton, Greene, Herkimer, Madison, Montgomery, Oneida, Onondaga, Oswego, Otsego, Rensselaer, Saratoga, Schenectady, Schoharie, Sullivan, Ulster, and Washington, but does not commit itself to a definition of Central New York ''per se''. Cortland County and Tompkins County are often considered part of the New York State region called the Southern Tier; the ski country demarcation line runs through Cortland County. Tompkins County, which includes Ithaca at the edge of Cayuga Lake, is also considered part of the Finger Lakes. Oneida County and Herkimer County are often considered part o ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and 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 were 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 , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Glacial Meltwater
Meltwater is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found in the ablation zone of glaciers, where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions, in a similar way in which the more dangerous lahars form. When meltwater pools on the surface rather than flowing, it forms melt ponds. As the weather gets colder meltwater will often re-freeze. Meltwater can collect or melt under the ice's surface. These pools of water, known as subglacial lakes can form due to geothermal heat and friction. Water source Meltwater provides drinking water for a large proportion of the world's population, as well as providing water for irrigation and hydroelectric plants. This meltwater can originate from seasonal snowfall, or from the melting of more permanent glaciers. Climate change threatens the precipitation of snow and the shrinking volume of glaciers.

Wisconsin Glaciation
The Wisconsin Glacial Episode, also called the Wisconsin glaciation, was the most recent glacial period of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from approximately 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred approximately 25,000–21,000 years ago during the last glacial maximum, also known as the ''Late Wisconsin'' in North America. This glaciation radically altered the ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canandaigua Outlet
The Canandaigua Outlet is a main tributary which feeds the Erie Canal and Clyde River in Wayne County, New York, United States. It begins at Canandaigua Lake in nearby Ontario County and flows approximately north before emptying into the Erie Canal in the hamlet of Lyons. A number of tributaries feed the Canandaigua Outlet along its route. It is the primary outflow for Canandaigua Lake. The Canandaigua Outlet is part of the Clyde River watershed which feeds the Seneca River. From there, the Seneca River enters the Oswego River and into Lake Ontario. It is used for fishing as well as whitewater canoeing, kayaking and rafting. Course The Canandaigua Outlet begins as a natural outflow on the north end of Canandaigua Lake in the city of Canandaigua. From there, the outlet travels northeast past the Muar Lakes through the town of Canandaigua and into the neighboring town of Hopewell. A man-made feeder canal also enters the outlet from Canandaigua Lake to help with drainage. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oncolite
Oncolites are sedimentary structures composed of oncoids, which are layered structures formed by cyanobacterial growth. Oncolites are very similar to stromatolites, but, instead of forming columns, they form approximately spherical structures. The oncoids often form around a central nucleus, such as a shell fragment, and a calcium carbonate structure is deposited by encrusting microbes. Oncolites are indicators of warm waters in the photic zone, but are also known in contemporary freshwater environments. These structures rarely exceed 10 cm in diameter. Oncolites may have either a porostromate or spongiostromate texture. Most oncolites are spongiostromate, having no recognisable cellular texture or microstructure. Porostromate oncolites are mostly unknown during the Precambrian; since the Eocene they have mostly been confined to freshwater environments. Distribution The appearance of recent or near-recent freshwater oncoids has been documented in two rivers in Bavaria: th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
