This includes the Catskill Mountains of southeastern New York, the Poconos in Pennsylvania, and the Allegheny Plateau of southwestern New York, western Pennsylvania, eastern Ohio and northern West Virginia . This same plateau is known as the Cumberland Plateau in southern West Virginia, eastern Kentucky, western Virginia, eastern Tennessee, and northern Alabama . </P> <P> The dissected plateau area, while not actually made up of geological mountains, is popularly called "mountains," especially in eastern Kentucky and West Virginia, and while the ridges are not high, the terrain is extremely rugged . In Ohio and New York, some of the plateau has been glaciated, which has rounded off the sharp ridges, and filled the valleys to some extent . The glaciated regions are usually referred to as hill country rather than mountains . </P>
