Appalachian Mountains
Blue Ridge, part of the Appalachian Mountains.
The Piedmont is a geographic region in the eastern United States that lies between the Appalachian Mountains to the west and the Atlantic Coastal Plain to the east.1
Specifically, the Piedmont is situated directly seaward of the Blue Ridge Mountains, which descend into it via an abrupt escarpment. It is characterized as a well-drained, rolling plateau with elevations ranging from approximately 300 to 1,800 feet (90 to 550 meters). Historically, it has been a highly productive agricultural area.21
The boundary between the Piedmont and the Atlantic Coastal Plain is marked by the fall line, where rivers transition from resistant rocks to weaker ones, creating numerous waterfalls and rapids.34
