The transition from the High Allegheny Plateau's ridges into the industrial corridor of Du Bois defines this 1929 survey. Extensive rural school networks like Oswald Sch, Coal Hill Sch, and Lines Sch reflect a time of small, dispersed communities linked by the Buffalo Rochester and Pittsburgh railroad. The map documents early aviation and communications infrastructure through an Airplane Landing Field and a strategically placed Beacon near Rockton.
