The West Virginia. Cyclopedia
The Seneca Trail, or Warrior's Path, was the Native American highway from upper New York into deep within Georgia. In West Virginia, it followed, in general, the Alleghenies. From the South Branch of the Potomac, at Seneca Rock, it crossed the Allegheny Mountains near the headwaters of the Cheat River, then, by way of Cheat Mountain and Shavers Fork of the Cheat, it led almost direct to Elkins. From there it continued westward, with a branch to the south.
When the King of England in 1763 issued a proclamation forbidding further settlement beyond the mountains and demanding the return of settlers who had already crossed the Alleghenies, a line was established roughly following the Seneca Trail. That line formed the boundary of "the frontier" during the French and Indian War. The highway comes into Tucker County near the famed Fairfax Stone, a boundary between West Virginia and Maryland.
