Allegheny Front
The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, eastern West Virginia, and western Virginia. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau (locally called the Allegheny Plateau) to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio River, Ohio/Mississippi River, Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean. The Allegheny Front and the Eastern Continental Divide do not always coincide; for example, the Potomac River, North Branch of the Potomac River begins well west of the Front, at the Fairfax Stone Historical Monument State Park, Fairfax Stone near the southwestern tip of Maryland, about and across the actual divide from ...

Allegheny Mountains
The Allegheny Mountain Range ( ) — also spelled Alleghany or Allegany, less formally the Alleghenies — is part of the vast Appalachian Mountain Range of the Eastern United States and Canada. Historically it represented a significant barrier to westward land travel and development. The Alleghenies have a northeast–southwest orientation, running for about from north-central Pennsylvania southward, through western Maryland and eastern West Virginia. The Alleghenies comprise the rugged western-central portion of the Appalachians. They rise to in northeastern West Virginia. In the east, they are dominated by a high, steep escarpment known as the Allegheny Front. In the west, they slope down into the closely associated Allegheny Plateau, which extends into Ohio and Kentucky. The principal settlements of the Alleghenies are Altoona, State College, and Johnstown, Pennsylvania; and Cumberland, Maryland. Using the USGS classification of physical geography (physiography) ...

Gulf Of Mexico
The Gulf of Mexico () is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the southeast by Cuba. The coastal areas along the Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are occasionally referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific coasts), but more often as "the Gulf Coast". The Gulf of Mexico took shape about 300 million years ago (mya) as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is about wide. Its floor consists of sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Straits of Florida between the ...

Western Maryland
upright=1.2, An enlargeable map of Maryland's 23 counties and one independent city Western Maryland, also known as the Maryland panhandle or Mountain Maryland, is the portion of the U.S. state of Maryland that typically consists of Washington, Allegany, and Garrett counties. The region is bounded by the Mason-Dixon line (Pennsylvania) to the north, the Potomac River and West Virginia to the south, and Preston County, West Virginia to the west. At one point, at the town of Hancock, the northern and southern boundaries are separated by just 1.8 miles, the narrowest stretch in the state. Western Maryland is more rural than the Washington-Baltimore area, where most of the state's population lives, and is noted for its mountainous terrain. The area is in the central Appalachians. Washington, Allegany, and Garrett counties are part of the Appalachian Regional Commission. The most populous community in Western Maryland is Hagerstown, located in Washington County, the most ...

Cumberland Plateau
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms " Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky. Geography The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about , and frequent sandstone outcroppings and bluffs. At Kentucky's Pottsville Escarpment, which is the transition from the Cumberland Plateau to the Bluegrass in the north and the Penny ...

Catskill Escarpment
The Catskill Escarpment, often referred to locally as just the Escarpment or the Great Wall of Manitou, and known as the Catskill Front to geologists, is the mountain range, range forming the northeastern corner of the Catskill Mountains in Greene County, New York, Greene and Ulster County, New York, Ulster counties in the U.S. state of New York (state), New York. It rises very abruptly from the Hudson Valley to summits above in elevation, including three of the Catskill High Peaks, with almost no foothills. The plateau to the south and west averages above sea level. The Escarpment was the first area of the Catskills to attract the interest of European colonization of the Americas, European settlers. Botanist John Bartram wrote a widely read account of an expedition there prior to American independence, independence, and a century later the North-South Lake area he had visited became home to a number of exclusive resorts, including the Catskill Mountain House.

Allegheny Portage Railroad
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania. It operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front. Approximately long overall, both ends connected to the Pennsylvania Canal, and the system was primarily used as a portage railway, hauling river boats and barges over the divide between the Ohio and the Susquehanna Rivers. Today, the remains of the railroad are preserved within the Allegheny Portage Railroad National Historic Site operated by the National Park Service. The railroad was authorized as part of the Main Line of Public Works legislation in 1824. It had five inclines on either side of the drainage divide running athwart the ridge line from Blair Gap through along the kinked saddle at the summit into Cresson, Pennsylvania. The endpoint ...

Wind Farm
A wind farm, also called a wind park or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore. Many of the largest operational onshore wind farms are located in China, India, and the United States.

Monongahela River
The Monongahela River ( , ), sometimes referred to locally as the Mon (), is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed August 15, 2011 river on the Allegheny Plateau in north-central West Virginia and Southwestern Pennsylvania. The river flows from the confluence of its west and east forks in north-central West Virginia northeasterly into southwestern Pennsylvania, then northerly to Pittsburgh and its confluence with the Allegheny River to form the Ohio River. The river includes a series of locks and dams that makes it navigable. Etymology The Unami word ''Monongahela'' means "falling banks", in reference to the geological instability of the river's banks. Moravian missionary David Zeisberger (1721–1808) gave this account of the naming: "In the Indian tongue the name of this river was ''Mechmenawungihilla'' (alternatively spelled ''Menawngihella''), which signifies a high bank, which is ever washed o ...

Drainage Basin
A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, " watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
