Fall Line

The Fall Line represents the contact between metamorphic crystalline rocks of the Piedmont with the sedimentary rocks of the Coastal Plain. Although this transition can be sharply delineated in places, it is best to think of the Fall Line as a transitional zone between the two areas. Commonly waterfalls and rapids occur in the vicinity of the Fall Line, hence its name.
