2011 Map of Portland
USGS Topo · Published 2011About this map
The Delaware River serves as the primary artery for this region of Warren County and eastern Pennsylvania, carving through the Delaware Water Gap where Indian Head and Mount Tammany rise above the banks. The river's influence on local development is evident in the cluster of settlements at Portland and Columbia, which are connected by the Columbia Dam and bridge infrastructure. Along the Paulins Kill and Delawanna Creek, smaller crossroads such as Hainesburg, Vail, and Knowlton define the landscape.
