In Virginia, the North and South Piedmont areas are considered by some as distinct regions both geographically and culturally. Virginia's Northern Piedmont stretches from the falls of the Potomac, Rappahannock, and James Rivers to the Blue Ridge Mountains. The region is about 50 miles wide and 100 miles long. At its northern corners are the major cities of Washington, D.C., and Harpers Ferry, West Virginia; on the southern corners, Charlottesville and Richmond, Virginia. It encompasses the counties of Loudoun, Fauquier, Prince William, Culpeper, Madison, Greene, Orange, Louisa, Albemarle and Fluvanna in Virginia. This area even has its own dialect called the Virginia Piedmont.
During my drives through the Northern Piedmont Region, I have noticed that the areas closer to the Blue Ridge Mountains tend to be poorer and more hilly, while closer to the ocean is flat and generally more wealthy, particularly nearer to Washington, DC.
