The divide's central portion generally follows the easternmost ridge of the Blue Ridge Mountains and thus of the Appalachian Mountains as a whole, which takes the form of a high escarpment. In this portion, the western drainage of the divide flows into the watersheds of the New River and Tennessee River, both tributaries of the Ohio River.

Blue Ridge Mountains - Front Royal, Virginia Although the term "Blue Ridge" is sometimes applied exclusively to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains, the Great Balsams, the Roans, the Blacks, and other mountain ranges.
