Glaciated Allegheny Plateau

Glaciated Allegheny Plateau

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.

A small area of the Allegheny Plateau was glaciated during the Pre-Illinoian B and G glaciations of the Pre-Illinoian Stage, the late Illinoian Stage, and the Wisconsin Stage.Richmond, G.M. and D.S. Fullerton, 1986, "Summation of Quaternary glaciations in the United States of America", Quaternary Science Reviews. vol. 5, pp. 183-196.] This area - only a few hundred square kilometers owing to the blockage the steep relief of the mountains provides at the edge of the ice sheet - contains only old drift now buried by long periods of soil development.

The major cities on the Glaciated Allegheny Plateau are Akron and Youngstown.
