The Baltimore And Ohio railroad winds through the narrow valleys of Allegheny County, serving as a primary corridor for the industrial and suburban growth of Glenshaw and Etna in the early 1960s. This survey illustrates a landscape in transition, where residential developments like Elfinwild and Allison Park expand across the ridges between the deeply incised paths of Pine Creek and Little Pine Creek. The presence of the Radio Sta (KDKA) tower and the Pennsylvania Turnpike slicing through the northern sections near Wildwood signals the area's role in regional communications and transport. Local history is deeply embedded in the map's details, from the numerous parochial schools such as St Nicholas Sch to the many community landmarks like the Little Red Brick Ch and the historic Talley Cavey crossing, providing a rich view of mid-century community life.
