Piedmont Region

      The Georgia Piedmont lies between the Blue Ridge Mountains and the Upper Coastal Plain. It is part of a larger area,

called the southern Piedmont and located in the southeastern and mid-Atlantic regions of the United States, that is about 1,400 kilometers long and 100 to 300 kilometers wide. It runs in a northeast-to-southwest direction, following the main axis of the mountains, faults, and coastline of the southeastern United States. The southern Piedmont extends from Alabama and Georgia northeastward through South Carolina and North Carolina.

      Geologists continue to study the origins of the rocks in the Piedmont province.The area is large and includes rocks ranging widely in age. The dynamic changes over time in this area are complex, but research has revealed the broad patterns of origin and development and specific structures in zones of special interest. The plateau of the Piedmont region has been formed largely on the edges of steeply upturned and altered rocks. Topographically, the Piedmont is made up of low hills and narrow valleys. The worn-down rocks of the Piedmont region pass below the sedimentary rocks of the Atlantic Coastal Plain for more than 150 miles from the fall line.
