context_page_description: The Piedmont Mountains are outlying mountains in the United States, sometimes called “low mountains”, that typically occur in the western Piedmont near the Blue Ridge. Most of the features within the Piedmont physiographic region 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 likely occur. Occasionally, due to diverse rock formations, folds and outcroppings, these mountains can rise at various locations across the Piedmont like the Uwharrie Mountains in North Carolina or the Pine Mountain Range in Georgia. Most of these mountains, or hills, are what is left of ancient eroded mountains. Some, like Stone Mountain in Georgia, are solitary rock domes called Monadnocks which become further exposed with erosion. The Piedmont is part of the greater Appalachian Mountain Range and is also referred to as the Appalachian Plateau. The French definition of piedmont in itself translates as foothill; however, a Piedmont Mountain may be that of greater significance or prominent elevation.
context_section_description: 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.  Therefore, the Piedmont Mountains in the Southeast occur less frequently (in a larger area) and are more prominent.  Once the Piedmont enters Pennsylvania it comes into contact with a total of four physiographic provinces as the Piedmont itself begins to terminate.  Here, the regional territories are less defined and the hills seem to scatter.  It is also in this vicinity that the Appalachian Trail leaves the Blue Ridge, climbs onto the Ridge and Valley (very near Piedmont Mountains) and enters the New England region.
