Cumberland Plateau
The Cumberland Plateau rises to the west of the Tennessee Valley. This landform is part of the larger Appalachian Plateau, and is mostly covered by flat-topped tablelands. The elevation of the Cumberland Plateau ranges from above sea level. The Cumberland Mountains, with peaks above , comprise the northeastern part of the Appalachian Plateau in Tennessee, and the southeastern part of the Cumberland Plateau is divided by the largely undeviating Sequatchie Valley. The plateau's eastern edge is relatively distinct, but the western escarpment is irregular, containing several long, crooked stream valleys separated by rocky cliffs that contain numerous waterfalls. The boundary between East and Middle Tennessee straddles the top of the Cumberland Plateau, as does the boundary between Eastern and Central Time.
