Delaware River currents divide Pennsylvania and New Jersey at the midpoint of this survey, where the industry of the past is still etched onto the landscape. The river valley is punctuated by several significant landmarks, most notably the site of Durham Furnace near the mouth of Durham Creek. This industrial legacy is set against a backdrop of small rural communities like Riegelsville, Kintnersville, and Ferndale. The terrain is characterized by distinctive elevations such as Rattlesnake Hill and Chestnut Hill, while the Penn Central rail line tracks the river's path, emphasizing the corridor's role in regional transport.
