1893 Map of Delaware Water Gap

About this map

Delaware River carved the iconic Delaware Water Gap through the Kittatinny Mountain long before this 1890s survey, but industrial expansion was quickly reshaping the valley floor. The map highlights a landscape defined by heavy extraction and transport, particularly around Bangor and its Old Bangor Slate Quarry. Extensive rail networks including the Bangor and Portland Railroad and the Belvidere Division Railroad weave through the gap, connecting industrial hubs like Oxford Furnace to the river trade. While steel bridges were becoming common, traditional river crossings like Myeres Ferry and Hartzells Ferry still appear, marking the transition from water-based transit to the dominant iron rail. High peaks like Mt Tammany and Jenny Jump Mountain loom over smaller settlements such as Portland and Columbia, providing a clear look at the topography that funneled commerce through these narrow mountain passes.
