The Southwestern Appalachians are the Cumberland Plateau and its escarpments, a sandstone tableland covered in oak and mixed mesophytic forest and cut by deep gorges. Creeks pour off the plateau rim over sandstone caprock into gorges, creating many tall, dramatic falls. Big Fiery Gizzard Creek carries 3 recorded waterfalls, and Black Canyon Cascades is the tallest of them.
