Map Of Long Island Topography
A map is a symbolic depiction emphasizing relationships between elements of some space, such as Physical body, objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to Context (language use), context or Scale (map), scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Long Island
Long Island is in southeastern New York, United States, separated from the rest of the state by the East River and from Connecticut by Long Island Sound. Long Island contains four counties, of which the western two are boroughs (Queens and Brooklyn) of New York City, and the other two (Nassau and Suffolk) are mainly suburban. Geology Long Island, as part of the Outer Lands region, is formed largely of four spines of glacial moraine, with a large, sandy outwash plain towards its barrier islands and the Atlantic Ocean. These moraines consist of gravel and loose rock left behind during the two most recent pulses of Wisconsin glaciation some 21,000 years ago (19,000 BC). The northern moraine, which directly abuts the North Shore of Long Island at points, is known as the Harbor Hill moraine. The more southerly moraine, known as the Ronkonkoma moraine, forms the "backbone" of Long Island; it runs primarily through the very center of Long Island, roughly coinciding with the length o ...

Long Island
Long Island is a densely populated island in the southeastern region of the U.S. state of New York (state), New York, part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the List of islands by population, 18th-most populous in the world. The island begins at New York Harbor approximately east of Manhattan Island and extends eastward about into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four List of counties in New York, counties: Kings and Queens counties (the New York City Borough (New York City), boroughs of Brooklyn and Queens, respectively) and Nassau County, New York, Nassau County share the western third of the island, while Suffolk County, New York, Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens. Culturally, many people in t ...

Terminal Moraine
A terminal moraine, also called end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from a previou ...

Harbor Hill Moraine
The Harbor Hill Moraine, in the geography of Long Island, forms the northern of two ridges along the "backbone" of Long Island. Description The Harbor Hill Moraine, skirting the North Shore, represents the terminal moraine of the most recent advance of the Wisconsinian glaciation, which reached its most southward advance about 18,000 years ago; the earlier Ronkonkoma Moraine, much cut through by outwash streams from the Harbor Hill Moraine, lies to the southeast. The Harbor Hill moraine is represented by the North Fork of eastern Long Island and in three disjunct sections farther east, Plum Island, Great Gull Island, and Fisher's Island. The Harbor Hill Moraine, named for its prominence at Harbor Hill, Roslyn, New York, the highest point in Nassau County, resulted from a lingering equilibrium stage in the glacier's episodic retreat, creating a stationary melting front; the Long Island area became permanently free of glacial ice in the range of 13,000 to 12,000 YBP (Years ...

Wisconsin Glacial Episode
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 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Success (lake)
Lake Success is a kettle lake in Lake Success, in Nassau County, on Long Island, in New York, United States. Description Lake Success was formed during the last ice age. The name of the lake is believed to be derived from the Native American chief "Sacut." The center of Lake Success is approximately deep. Lake Success is the source of the name of the village it is located in: Lake Success, New York. Lake Success marks the location where the Harbor Hill Moraine and the Ronkonkoma Moraine meet. West of Lake Success, the Harbor Hill Moraine overrode the Ronkonkoma Moraine. See also * Lake Ronkonkoma – Another kettle lake on Long Island, located in neighboring Suffolk County. References Success Success is the state or condition of meeting a defined range of expectations. It may be viewed as the opposite of failure. The criteria for success depend on context, and may be relative to a particular observer or belief system. One person mig ... {{NassauCountyNY- ...

South Fork (Long Island)
The South Fork of Suffolk County, New York is a peninsula in the southeastern section of the county on the South Shore of Long Island. The South Fork includes most of the Hamptons. The shorter, more northerly peninsula is known as the North Fork. Geography The South Fork is composed of all of the Town of East Hampton and a substantial part of the Town of Southampton. The body of water to the south is the Atlantic Ocean. The South Fork and North Fork split at Riverhead, New York where the Peconic River empties into Peconic Bay. It has long been noted that Long Island resembles a fish with the forks forming a tail. The native name for this is "Paumanok". This name is also used to name a trail that navigates the entirety of the South Fork (as well as parts of Long Island), the Paumanok Path. The South Fork and North Fork are separated by Great Peconic Bay, Little Peconic Bay, and Gardiners Bay. Between the two forks lie several islands, including Gardiners Island and She ...

Bald Hill (Farmingville, New York)
Bald Hill, located in the hamlet of Farmingville, New York, part of the Town of Brookhaven, is one of the highest areas of elevation on Long Island. The highest elevation in the Bald Hill area is . Though local residents often claim it to be the highest point on Long Island, ("Mr. Venezio insists that the Bald Hill Ski Bowl is situated on the highest spot on Long Island, although there is some dispute about this from people who live in Southampton.") that honor actually belongs to Jayne's Hill in the Town of Huntington at . Also, nearby Telescope Hill, about WSW, is slightly higher at . Bald Hill in Brookhaven should also not be confused with Bald Hill in Riverhead. History The Bald Hill area is part of the Ronkonkoma Moraine, which runs east to west along the center of the Town of Brookhaven, and marks where the glacier which formed Long Island stopped its advance. When first settled in the late 18th century, the area was called "Bald Hills." While the elevation and views ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescope Hill
Telescope Hill, at , is the highest point of elevation in the Town of Brookhaven, on Long Island, New York, United States. The hill is located at the end of Tower Hill Ave., on the border of the ZIP codes of the hamlets of Selden and Farmingville, and west of Bald Hill. Notably, Telescope Hill was the site of a fire observation station operated by the New York State Conservation Commission and later the Conservation Department from 1918 to 1959. Geology As with the Bald Hill area, Telescope Hill is part of the Ronkonkoma Moraine, which runs east to west along the center of the Town of Brookhaven, and marks where the glacier which formed Long Island stopped its advance. Fire Lookout Tower Beginning in 1918, a series of fire lookout towers were constructed on Long Island to aid in the fighting of wildfires. The first constructed was on Telescope Hill in the fall of 1918 (only two were constructed that year), and went into operation in March 1919.Bill Starr, The Fire Tow ...
