Allegheny plateau map

Map of the Allegheny plateau. The gray line divides the glaciated (northern) and unglaciated (southern) sections of the plateau.

The Allegheny Plateau is a large dissected plateau area 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 (Southern part) and the Glaciated Allegheny Plateau (Northern part).

Glaciated Allegheny PlateauEdit

The Glaciated Allegheny Plateau is that portion of the Allegheny Plateau that lies within the area covered by the last glaciation. As a result, this area of the Allegheny Plateau has lower relief and more gentle slopes than the relatively rugged Unglaciated Allegheny Plateau. In general, the glaciated lies to the north and west of the unglaciated, and forms an arc in northeastern to southeastern Ohio lying between the glacial till plains and the Unglaciated Allegheny Plateau. The Glaciated Allegheny Plateau extends into a belt of southern New York state and the central Susquehanna River basin.
