Appalachian Plateau
The Appalachian Plateau is a series of rugged dissected plateaus located on the western side of the Appalachian Mountains. The Appalachian Mountains are a mountain range that run down the Eastern United States. The Appalachian Plateau is the northwestern part of the Appalachian Mountains, stretching from New York to Alabama. The plateau is a second level United States physiographic region, covering parts of the states of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Alabama, and Georgia. Geography and physical features The formation of the plateau began during the Paleozoic Era. Regional uplift during this time caused the area to rise altogether without changing the topography of the land. The eastern side of the plateau appears as a mountain range. This false appearance is due to a very steep slope on the eastern side known as the Allegheny Front. The eastern edge is the highest part of the Appalachian Plateau. In Pennsylvania, the ele ...

Quaternary Glaciation
The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing. Although geologists describe this entire period up to the present as an "ice age", in popular culture this term usually refers to the most recent glacial period, or to the Pleistocene epoch in general. Since Earth still has polar ice sheets, geologists consider the Quaternary glaciation to be ongoing, though currently in an interglacial period. During the Quaternary glaciation, ice sheets appeared, expanding during glacial periods and contracting during interglacial periods. Since the end of the last glacial period, only the Antarctic and Greenland ice sheets have survived, with other sheets formed during glacial periods, such as the Laurentide Ice Sheet, having completely melted. The major effects of the Quaternary glaciation have been the continental erosion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kanawha County, West Virginia
Kanawha County ( ) is a county in the U.S. state of West Virginia. As of the 2020 census, the population was 180,745, making it West Virginia's most populous county. The county seat is Charleston, which is also the state capital. Kanawha County is part of the Charleston, WV Metropolitan Statistical Area. History The county began taking formation on November 14, 1788, under the authorization of the Virginia General Assembly and was founded on October 5, 1789. The county was named for the Kanawha River, which in turn was named after a Native American tribe that lived in the area. (WV County Etymology) During the American Civil War, a number of state infantry and cavalry regiments were organized in the county for both Confederate Army and Union Army service. In 1863 West Virginia's counties were divided into civil townships, with the intention of encouraging local government. This proved impractical in the heavily rural state, and in 1872 the townships were converted into mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allegheny Mountains
The Allegheny Mountain Range (; also spelled Alleghany or Allegany), informally the Alleghenies, is part of the vast Appalachian Mountain Range of the Eastern United States and Canada and posed a significant barrier to land travel in less developed eras. The Allegheny Mountains 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 approximately 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. Name The name is derived from the Allegheny River, which drains only a small porti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catskill Mountains
The Catskill Mountains, also known as the Catskills, are a physiographic province of the larger Appalachian Mountains, located in southeastern New York. As a cultural and geographic region, the Catskills are generally defined as those areas close to or within the borders of the Catskill Park, a forest preserve protected from many forms of development under New York state law. Geologically, the Catskills are a mature dissected plateau, a flat region subsequently uplifted and eroded into sharp relief by watercourses. The Catskills form the northeastern end of the Allegheny Plateau (also known as the Appalachian Plateau). The Catskills were named by early Dutch settlers. They are well known in American society as the setting for films and works of art, including many 19th-century Hudson River School paintings, as well as for being a favored destination for vacationers from New York City in the mid-20th century. The region's many large resorts gave many young stand-up comedian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mohawk Mountains
The Mohawk Mountains ( mrc, Vii Kachkwiny, ood, Kusvo To:b) is a mountain range in the northwest Sonoran Desert of southwest Arizona. It abuts the western Gila River valley to the north (the Lower Gila River Valley), and is located in southern Yuma County. The Mohawk Valley lies adjacent and southwest of the range; the San Cristobal Valley is northeast.''Arizona Atlas & Gazetteer,'' DeLorme, 4th ed., 2001, p. 63, The Mohawk Mountains-Bryan Mountains is a northwest–southeast trending block faulted system.

Appalachian Highlands
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 Valley, Appalach ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...

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," sepa ...

Cumberland Mountains
The Cumberland Mountains are a mountain range in the southeastern section of the Appalachian Mountains. They are located in western Virginia, southwestern West Virginia, the eastern edges of Kentucky, and eastern middle Tennessee, including the Crab Orchard Mountains. Their highest peak, with an elevation of above mean sea level, is High Knob, which is located near Norton, Virginia. According to the USGS, the Cumberland Mountain range is long and wide, bounded by the Russell Fork on the northeast, the Pound River and Powell River on the southeast, Cove Creek on the southwest, and Tackett Creek, the Cumberland River, Poor Fork Cumberland River, and Elkhorn Creek on the northwest. The crest of the range forms the Kentucky and Virginia boundary from the Tennessee border to the Russell Fork River. Variant names of the Cumberland Mountains include Cumberland Mountain, Cumberland Range, Ouasioto Mountains, Ouasiota Mountains, Laurel Mountain, and Pine Mountain. They are name ...

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 Pennyril ...
