Unglaciated Allegheny Plateau

The Unglaciated Allegheny Plateau is located in an arc around southeastern Ohio, West Virginia, into western Pennsylvania and a small portion of southwestern New York State.

This area is a dissected plateau, characterized by sandstone, shale, and many coal seams.

This is the part of the Allegheny Plateau that lies outside the continental glaciation of the ice age.

This area, similar to but smaller than the Red River Gorge in the Cumberland Plateau in Kentucky, features cliffs, rock shelters and waterfalls.

The Ohio River roughly bisects the Unglaciated Allegheny Plateau in generally a north-northeast to south-southwest direction.
