Tennessee’s seven natural regions lie between the Blue Ridge Mountains on the east, and the Mississippi River on the west. The Tennessee portion of the Blue Ridge Mountains is known as the Unaka Range, a sparsely populated and mostly forested region along the Tennessee-North Carolina border. Within the Unaka Chain is a large portion of the Great Smoky Mountains National Park, including Clingmans Dome, which rises to 2,025 m (6,643 ft) above sea level and is the highest point in Tennessee.
