The Allegheny River defines the western corridor of this map, winding past a series of river islands and named eddies. Settlements like Cobham and Magee are situated along the riverbanks, where the valley terrain meets the mouths of several tributary runs including Waid Run and Perry Magee Run. This river-oriented landscape transitions into the high, dissected plateaus of the Allegheny National Forest, marked by deep valleys such as Bully Hollow and Beers Hollow.
