South Mountains (North Carolina) South Mountains (North Carolina) The South Mountains are an ancient and deeply eroded mountain range in western North Carolina. They are an isolated remnant of the much larger Appalachian Mountains to the west, and are separated from the Appalachians by the Catawba River valley. The range covers approximately 100,000 acres (400 km²) in Burke, Cleveland, McDowell and Rutherford counties. The South Mountains are the highest and most rugged chain of the isolated mountain ranges which dot North Carolina's Piedmont region. The highest point in the range is Buzzard Roost, which rises to 2,980 feet (908 m) above sea level. The
