Sequatchie Valley

It is generally considered to be part of the Cumberland Plateau region of the Appalachian Mountains; it was probably formed by erosion of a compression anticline, rather than rifting process as had been formerly theorized.

Geologically, the Sequatchie Valley continues south of the Tennessee River into central Alabama.

The portion of the plateau east of the valley is relatively narrow and known as Walden Ridge in Tennessee.

Another, smaller karst valley, Bat Town Cove, is forming northeast of Grassy Cove, which may also grow and eventually become part of Sequatchie Valley.

Towns in the Alabama portion of the geologic valley include Bridgeport, Scottsboro, Guntersville, and, around the southern end, Blountsville.
