Fairfax Stone State Park

Fairfax Stone Historical Monument State Park is a West Virginia state park commemorating the Fairfax Stone, a surveyor's marker and boundary stone at the source of the North Branch of the Potomac River. The original stone was placed on October 23, 1746, to settle a boundary dispute between Thomas Fairfax, 6th Lord Fairfax of Cameron and the Privy Council of Great Britain concerning the Northern Neck of Virginia. It determined the proprietorship and boundaries of a large tract of mostly unsurveyed land in the British colonies of Maryland and Virginia.
