How did an ancient geologic fault line form this 120 mile long valley?

Today's Appalachian Mountains are a product of long-term erosion interacting with much older geologic structures. The Sequatchie Valley is one of the best examples of how Appalachian landscapes are a product of erosional forces sculpting existing folds within the bedrock. One of the Sequatchie Valley's most interesting aspects is that a fault runs for most of its nearly 120 mile (200 km) length. The role of the fault in actually forming the valley is not immediately obvious, and a look at the landscape, along with a Microsoft Paint sketch, are necessary to see how the fault and the rocks interact to make one of the regions longest landforms.
