The Anglo-Saxons of the Kentucky I\Iou}itains Appalachians arc distinguished by a central zone of depression, flanked on the east by the Appalachian Mountains jiroper, and on tiie west by the Allegheny and the Cumberland JMatcaus. This central trough is generally designated as the Great Ap[)alachian \ alley. It is depressed several hundred feet below the highlands on either side, but its surface is relieved by intermittent series of even-crested ridges which rise looo feet or juore above the general level, running parallel to each other, and conforming at the same time to the structural axis of the whole system. The valleys between them owe neither width nor form to the streams which drain them. The Cumberland I'lateau forms the western highland of the Great Valley in Eastern Kentucky, 'J'ennessee, and Northern Alabama. This plateau belt reaches its greatest height in Kentucky, and slopes gradually from this section to the south and west. Its eastern escarpment rises abruptly (Soo to 1500 feet from the Great Valley, and shows everywhere an almost perfectly straight skyline. The western escarpment is very irregular, for the streams, flowing westward from the plateau, have carved out their valleys far back into the elevated district, leaving narrow spurs running out into the low plains beyond. The surface is highly dissected, presenting a maze of gorge-like valleys separating the steep, regular slopes of the sharp or rounded hills. The level of the originally upheaved mass of the plateau is now represented by the altitude of the existing summits, which show a remarkable uniformity in the northeast-southwest line, and a slight rise in elevation from the western margin towards the interior. About 10,000 square miles of the Cumberland Plateau fall within the confines of the State of Kentucky, and form the eastern section of the State. A glance at the topographical map of the region shows the country to be devoted by nature to isolation and poverty. The eastern rim of the plateau is formed by Pine Mountain, which raises its solid wall with level top in silhouette against the sky, and shows only one water-gap in a distance of 150 miles. And just beyond is the twin range of the Cumberland. Hence no railroads have attempted to cross this double border-barrier, except at the northeast and southeast corners of the State, where the Big Sandy and Cumberland Rivers have carved their way through mountains to the west. Railroads, therefore, skirt this upland region, but nowhere penetrate it. The whole area is a coalfield, the mineral being chiefiy bituminous, with several thousand square miles of superior canne! coal.
