1936 Map of Delaware Water Gap

About this map

The Delaware River cuts through the ancient ridges of Blue Mountain at the iconic Water Gap, forming a natural corridor for some of the region's most important early infrastructure. This landscape is defined by its deep rail history, featuring the Delaware Lackawanna and Western RR and the Belvidere Delaware RR, which follows the river's winding course. The valley is dotted with historic settlements like Oxford Furnace and Portland, while an Emergency Landing Field near Hutchinsons and Fire Lookout Towers atop Mt Minsi and Mt Tammany indicate the transition into early 20th-century aviation and forest management.
