The Tennessee River Gorge is a 26-mile (42 km) canyon formed by the Tennessee River known locally as Cash Canyon. It is the fourth largest river gorge in the Eastern United States. The gorge is cut into the Cumberland Plateau as the river winds its way into Alabama from Tennessee. The Tennessee River Gorge was also known as Walden Gorge. Walden Ridge originally extended across the present path of the Tennessee River at the gorge to Sand Mountain.[1]
