Fairfax Stone Historical Monument 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.

Fairfax Stone Historical Monument, part of a four-acre West Virginia state park, is six miles north of Thomas, West Virginia. The site is sparsely developed, lacking any buildings or restroom facilities.History
The exact boundaries of the "Northern Neck Land Grant" had been undetermined since it was first contrived in 1649 by the then-exiled Charles II of England.John Savage and his survey party had located the site of the source of the North Branch of the Potomac River in 1736, but had made no attempt to establish the western boundaries. A 1746 survey by Colonel Peter Jefferson and Thomas Lewis resulted in both the placement of the Fairfax Stone as well as the establishment of a line of demarcation known as the "Fairfax Line", extending from the Stone to the south-east and ending at the source of the Rappahannock River, a distance of.
In 1748, George Washington, along with frontiersman and noted surveyor David Morgan of Virginia, had surveyed the area again. Their job was to establish the northernmost boundary of Lord Fairfax's land and estate, on the present day borders of Maryland and West Virginia. They placed the Fairfax Stone where it is today for a consummation of their hard work.
The North Branch of the Potomac River initially heads west from its source at the Fairfax Stone before curving north and then generally flowing east toward Chesapeake Bay. For this reason, the Stone is only a county corner of West Virginia counties rather than part of the state's border with Maryland, an issue that was only resolved when the Supreme Court ruled against Maryland in 1910 in Maryland v. West Virginia, determining that Maryland would only go westward up the Potomac far enough to meet a point where a line north from the Fairfax Stone would cross that branch of the Potomac. Until the ruling, the boundary of Maryland was indeterminate. Three West Virginia counties—Grant, Preston and Tucker— share the boundary marked by the Fairfax Stone.
The site was placed on the National Register of Historic Places on January 26, 1970.
