What ridge is part of the Appalachian Plateau
Walden Ridge Walden Ridge (or Walden's Ridge) is a mountain ridge and escarpment located in Tennessee, in the United States. It marks the eastern edge of the Cumberland Plateau and is generally considered part of it. Walden Ridge is about 74 mi long, running generally north-south. Its highest point is at Hinch Mountain (near Crossville), which reaches 3048 ft above sea level.
Piedmont Mountains The Piedmont Mountains are outlying mountains, sometimes called “low mountains”, that typically occur in the western Piedmont near the Blue Ridge. Most of the features within the Piedmont physiographic region of North America lie either on the eastern border where the plateau plunges onto the Coastal Plain at the Fall Line, in the broad valleys of the river systems, or on the western border where Piedmont Mountains likely occur. Occasionally, due to diverse rock formations, folds and outcroppings, these mountains can rise at various locations across the Piedmont like the Uwharrie Mountain Range in North Carolina or the Pine Mountain Range in Georgia. Most of these mountains, or hills, are what is left of ancient eroded mountains. Some, like Stone Mountain in Georgia, are solitary rock domes called Monadnocks which become further exposed with erosion. The Piedmont is part of the greater Appalachian Mountain Range and is also referred to as the Appalachian Plateau. The French definition of piedmont in itself translates as foothill; however, a Piedmont Mountain may be that of greater significance or prominent elevation.
