- Cumberland Mountain Thrust Fault
- Eastern Escarpment
- Cumberland Plateau
- Western Escarpment
- Eastern Highland Rim
The eastern edge of the plateau is about 750 feet higher than the lowlands of the eastern adjacent Cumberland Mountain Thrust Fault and Valley and Ridge Provinces. Very long linear valleys paralleled by ridges, all running northeast to southwest, with local relief of several hundred feet or more, characterize the topography of the Thrust Fault and Valley and Ridge.
The top of the Cumberland Plateau is primarily 1,700 to 1,900 feet in elevation. The topography at the top of the plateau is primarily flat with some rolling hills that can reach up to 3,000 feet in elevation and gorges to 900 feet. From the west, the Western Escarpment of the Plateau transitions to the Eastern Highland Rim that drops approximately 1,000 feet from the elevation of the Cumberland Plateau.
Another way to categorize geographic regions is by ecoregion. An ecoregion is “a relatively large area of land or water that contains a geographically distinct assemblage of natural communities.” Each ecoregion is assigned a standard identification number for mapping reference and additional research activities.
