The 'Fairfax Stone' was a
surveyor's marker, placed to settle a boundary dispute between
Thomas Fairfax, 6th Lord Fairfax of Cameron and the English
Privy Council concerning the
Northern Neck of the
Potomac River, and to determine the proprietorship and boundaries of a large tract of largely unsurveyed land in the colonies of
Maryland and
Virginia during the Survey of 1736/37.
John Savage and his party made the survey, the results of which include both the placement of the Fairfax Stone as well as the establishment of a line of demarcation known as the Fairfax Line, which extends from the Fairfax Stone south to the headwaters of the
Rappahannock River.

Fairfax Stone
The
stone marks the headwaters of the
North Branch Potomac River.
Although the original stone is believed lost (as the stone was most likely simply a natural, unmarked rock selected from among the outcroppings common to the area, in accordance with common surveying practices of the era), nonetheless a replica is maintained at the original site near
Garrett County,
Maryland, marking what should theoretically represent a corner of the State of Maryland. Because of the way the head of the Potomac River bends around, the stone is only a county corner of West Virginia counties. This issue was only resolved when the Supreme Court ruled against Maryland in determining that Maryland would only go up the Potomac far enough to meet a point where a North line from the Fairfax stone would cross the branch of the Potomac. Without the ruling, the boundary of Maryland was indeterminate.
West Virginia counties—
Tucker County and
Preston County— share the boundary marked by the Fairfax Stone (West Virginia having seceded from
Virginia during the
United States Civil War).
