In this article Allegheny Plateau will be analyzed in detail, with the aim of delving into its importance, impact and relevance in today's society. Allegheny Plateau is a topic that has gained great interest in recent years, and its influence covers different areas, from technology to culture. Through a multidisciplinary approach, various aspects related to Allegheny Plateau will be addressed, such as its history, evolution, implications and possible future scenarios. By collecting data, expert opinions and critical analysis, this article seeks to provide a comprehensive and updated vision of Allegheny Plateau, in order to contribute to the debate and reflection on this topic.
The Allegheny Plateau (/ˌælɪˈɡeɪni/ AL-ig-AY-nee) is a large dissected plateau area of the Appalachian Mountains in western and central New York, northern and western Pennsylvania, northern and western West Virginia, and eastern Ohio. It is divided into the unglaciated Allegheny Plateau and the glaciated Allegheny Plateau.
The plateau extends southward into western West Virginia, eastern Kentucky, and Tennessee, where it is instead called the Cumberland Plateau.
The plateau terminates in the east at the Allegheny Mountains, which are the highest ridges just west of the Allegheny Front. The Front extends from central Pennsylvania through Maryland and into eastern West Virginia.
The plateau is bordered on the west by glacial till plains in the north, generally north of the Ohio River, and the Bluegrass Region south of the Ohio River.
Elevations vary greatly. In the glaciated Allegheny Plateau, relief may only reach one hundred feet or less. In the unglaciated Allegheny Plateau in southeastern Ohio and westernmost West Virginia, relief is typically in the range of two hundred to four hundred feet. Absolute highest elevations in this area are often in the range of 900 to 1,500 feet (270 to 460 m). By the Allegheny Front, however, elevations may reach well over 4,000 feet (1,200 m), with relief of up to 2,000 feet (610 m).
Geology and physiography
The Allegheny Plateau is a physiographic section of the larger Appalachian Plateau province, which in turn is part of the larger Appalachian physiographic division.
