The North Branch Potomac River forms the winding state boundary between Maryland and West Virginia, anchoring a corridor of industrial and residential development. Clusters of settlement at Westernport, Luke, and Piedmont reveal the area's history as a regional hub for transportation and manufacturing. Along the steep slopes of the Allegheny Front, numerous small family burial sites such as the Thomas Family Cem and Sinkler Cem are preserved, offering valuable clues for genealogists and local historians researching the early families of Garrett and Mineral counties.
