To the west of the Appalachian Plateau lies the Highland Rim, an elevated plain with steep slopes, surrounding the Central Basin, or Nashville Basin. The Nashville Basin is characterized by rich, fertile farm country.
With the exception of a few broad stream bottoms, the land is characterized by ridges and valleys with a few fairly low hills. The entire region is sprinkled with many perennial streams and occasional waterfalls, which sometimes delineate the Rim from the Basin which it surrounds.
The eastern portion of the Rim rises approximately fifty miles east of Nashville, bordered to its east by even higher terrain, the Cumberland Plateau.
