The Allegheny River valley dictates the geography of this 1930 edition, with the Pennsylvania Railroad and State Highway No. 33 following its winding course past industrial and timber settlements. In Tidioute, the river forms a sharp bend, serving as a hub for nearby logging and oil operations in the Allegheny National Forest. The map documents a transition from early timber wealth to a more established rural infrastructure, evidenced by the numerous small schoolhouses like Watson Sch and Pleasant Grove Sch scattered across the high ridges.
