Tennessee Valley

The Tennessee Valley is the drainage basin of the Tennessee River and is largely within the U.S. state of Tennessee. It stretches from southwest Kentucky to north Georgia and from northeast Mississippi to the mountains of Virginia and North Carolina. The border of the valley is known as the Tennessee Valley Divide. The Tennessee Valley contributes greatly to the formation of Tennessee's legally recognized Grand Divisions. Tennessee Valley is a generally accepted term for North Alabama, anchored by the city of Huntsville (analogous to referring to Greater Philadelphia as the Delaware Valley).
