Delaware Water Gap serves as the focal point for this 1930s topographic survey, where the Delaware River cuts through the massive ridges of Blue Mountain. The map captures a complex industrial and transport network at the height of the steam era, featuring the New York Susquehanna and Western RR and the Lehigh and New England RR threading through narrow river gaps and valleys. To the west, the slate-producing region near Bangor and Pen Argyl is densely settled, while the higher elevations of Godfrey Ridge and Scotts Mountain remain largely rural.
