Is there a fall line in Alabama?

In Alabama, the fall line isn’t always a steep drop. As you travel from Opelika to Montgomery, you’ll notice a shift in slope where the sturdy Piedmont rocks meet the sand and gravel of the Coastal Plain. The change is clear, with the Piedmont rocks supporting a plateau that sits 150 to 200 feet above the Coastal Plain rocks.

What is the fall line known for?

The eastern United States is home to a significant fall line, separating the tough Appalachian Piedmont rock from the gentle sediment of the Atlantic Coastal Plain. Early European explorers found this line crucial as it signaled the end of river travel for their ships.

Why is the divide called the fall line?

The fall line, also known as the fall zone, is where an elevated area meets a coastal plain, often creating rapids or waterfalls where rivers flow across it. The uplands consist of tough, crystalline basement rock, while the coastal plain is made up of softer sedimentary rock.

Why is it called the fall line?

Rivers running on the fall line form waterfalls and rapids, hence the name “fall line”. The geological areas north of this line comprise the Appalachian Plateau, the Valley and Ridge, the Blue Ridge, and the Piedmont.
