The Potomac River begins as a small spring at Fairfax Stone in West Virginia, marking the northern corner of a royal land grant to Lord Fairfax in the 17th century. From this trickle, through the mountains of West Virginia and the valleys of the Appalachian Piedmont, beside the nation's ccapitl city, the Potomac River widens to the great historic waterway, fully ten miles from shore to shore at its mouth. Almost 400 miles long, the Potomac River passes through ancient settlements and hunting grounds of natives peoples, land grants to royal colonies, homes of the Founding Fathers, battlefiends of the Civil War and more.
