Cumberland serves as the industrial and transit hub of this 1949 survey, where the Potomac River and Wills Creek intersect at the base of Wills Mountain. The topographic detail highlights the dramatic geological gap known as The Narrows, a critical passage for the Western Maryland RR and other lines connecting the coalfields of the Allegheny Plateau to the coastal markets. To the north, the historic Mason and Dixon Line defines the border between Maryland and Pennsylvania, passing through the settlements of Wellersburg and Ellerslie.
