Piedmont Mountains

[1] Most of the features within the Piedmont physiographic province of North America lie either on the eastern border where the plateau plunges onto the Atlantic Coastal Plain at the Fall Line, in the broad valleys of the river systems, or on the western border where Piedmont Mountains occur.

[2] Some, like Stone Mountain in Georgia, are solitary rock domes called monadnocks which become further exposed with erosion.

[3] The Piedmont extends north from mid-eastern Alabama to extreme southern New York.

Almost ninety percent of the Piedmont lies south below the Mason–Dixon Line before permeating into the New England region.

[4] Therefore, the Piedmont Mountains in the Southeast occur less frequently (in a larger area) and are more prominent.
