“ The greater part of the mountain region, occupying more than one-third of the State, belongs to the Alleghany Plateau, though the mountains in the extreme southern section may be considered as a northern extension of the Cumberland Plateau. The mountains of the northeast are chiefly in the form of parallel ridges with a southwest and northeast trend, but the southern part of the plateau is irregularly dissected by river valleys, presenting broad domes with spurs running in all directions, and but few definite ridges. ”
