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 miles long (119 km), running generally north-south. Its highest point is called "Hinch Mountain", which is 3,048 feet high (929 meters).Sequatchie Valley, a long valley in the Cumberland Plateau, is located just west of the southern part of Walden Ridge. The Sequatchie River runs through the valley. To the east of Walden Ridge is the Ridge-and-valley Appalachians and the Tennessee River. Walden Ridge is significantly higher than the Cumberland Plateau, and its eastern slope, descending over 1,000 feet from the plateau to the Tennessee Valley, is steep and escarpment-like. Sometimes Walden Ridge is called the "Cumberland Escarpment". Geologically, Walden Ridge continues south in Alabama as Sand Mountain.
