HAGERSTOWN, Md. (AP) — Many of the centuries-old stone markers are weathered and difficult to decipher, but their importance to American history holds strong today just like the boundary line they represent.
This year marks the 250th anniversary of the completion of the famed Mason-Dixon Line, established as the remedy to a contentious boundary dispute between several British colonies in the 1760s.
The line still exists in the same form it did when it was completed in 1767 by surveyors Charles Mason and Jeremiah Dixon, creating the borders of Maryland, Pennsylvania, Delaware and, eventually, West Virginia.
