Walden Ridge
Walden 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 long, running generally north-south. Its highest point is at Hinch Mountain, which reaches above sea level.
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 are the Ridge-and-valley Appalachians and the Tennessee River. Walden Ridge is significantly higher than the Cumberland Plateau, and its eastern slope, descending over 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 Georgia and Alabama as Sand Mountain.
The section of Walden Ridge that is visible from the Chattanooga area is often colloquially referred to as "Signal Mountain" due to the presence of the small town of Signal Mountain, Tennessee nearby, the proliferation of broadcasting towers on its eastern edge, and the area's use by early nineteenth century Native Americans as a signal point toward Lookout Mountain south across the Tennessee River.
Being part of the Cumberland Plateau, Walden Ridge is also part of the Appalachian Plateau physiographic province.
According to the USGS, variant names of Walden Ridge include Waldens Ridge, Walldenns Ridge, Wallens Ridge, Walden's Ridge, and Walden Ridge Plateau.
