1992 Map of Portland
USGS Topo · Published 1995About this map
Kittatinny Mountain dominates the northwestern landscape, where the Appalachian Trail follows the ridgeline through the Worthington State Forest. The geography is defined by the deep cut of the Delaware River, which separates Pennsylvania and New Jersey at the iconic The Gap. This 1992 photo-inspection, based on earlier Army Map Service work, illustrates the transition from the river-bottom industrial sites like the powerplant and its conveyors near Portland to the agricultural and recreational lands of Knowlton and Blairstown.
