The Allegheny River carves a deep, sinuous path through this 1900 survey of Armstrong and Butler Counties, dictating the placement of early industrial hubs and transport lines. Industrial activity is prominent along the riverbanks, most notably at Redbank Furnace and within the developed street grid of Kittanning. To the west, the landscape transition into more dissected plateau country where milling operations like Buffalo Mills and Fosters Mills established local economic centers.
