Tennessee Area Information
Tennessee Area Information
Tennessee borders eight other states: Kentucky and Virginia to the north; North Carolina to the east; Georgia, Alabama and Mississippi on the south; Arkansas and Missouri on the Mississippi River to the west. Tennessee ties Missouri as the state bordering the most other states. The state is trisected by the Tennessee River. The highest point in the state is Clingmans Dome at 6,643 feet (2,025 m). Clingmans Dome, which lies on Tennessee's eastern border, is the highest point on the Appalachian Trail. The state line between Tennessee and North Carolina crosses the summit. The lowest point is the Mississippi River at the Mississippi state line. The geographical center of the state is located in Murfreesboro.
The state of Tennessee is geographically and constitutionally divided into three Grand Divisions: East Tennessee, Middle Tennessee, and West Tennessee. Tennessee features six principal physiographic regions: the Blue Ridge, the Appalachian Ridge and Valley Region, the Cumberland Plateau, the Highland Rim, the Nashville Basin, and the Gulf Coastal Plain. Tennessee is home to the most caves in the United States, with over 8,350 caves registered to date.
The Blue Ridge area lies on the eastern edge of Tennessee, bordering North Carolina. This region of Tennessee is characterized by the high mountains and rugged terrain of the western Blue Ridge Mountains, which are subdivided into several subranges, namely the Great Smoky Mountains, the Bald Mountains, the Unicoi Mountains, the Unaka Mountains and Roan Highlands, and the Iron Mountains. The average elevation of the Blue Ridge area is 5,000 feet (1,500 m) above sea level. Clingmans Dome, the state's highest point, is located in this region. The Blue Ridge area was never more than sparsely populated, and today much of it is protected by the Cherokee National Forest, the Great Smoky Mountains National Park, and several federal wilderness areas and state parks.
Stretching west from the Blue Ridge for approximately 55 miles (88 km) is the Ridge and Valley region, in which numerous tributaries join to form the Tennessee River in the Tennessee Valley. This area of Tennessee is covered by fertile valleys separated by wooded ridges, such as Bays Mountain and Clinch Mountain. The western section of the Tennessee valley, where the depressions become broader and the ridges become lower, is called the Great Valley. In this valley are numerous towns and two of the region's three urban areas, Knoxville, the 3rd largest city in the state, and Chattanooga, the 4th largest city in the state.
