This inventory is an effort to identify each township’s most prominent through valley, or through valleys and many less prominent through valleys are not included. The through valleys provide evidence of former drainage routes that can best be explained in the context of massive and prolonged southwest oriented floods that were sequentially captured by headward […]

Figure 1: Buckingham Mountain region in Bucks County, PA. United States Geological Survey topographic map digitally presented using National Geographic TOPO software. Buckingham Mountain in Bucks County is a high southwest-to-northeast oriented ridge (more than 500 feet at its highest point while surrounding landscape elevations are in the 200-300 foot range). According to the Pennsylvania […]
Figure 1: Delaware Bay extends from northeast of Philadelphia to Cape May and is a drowned river valley.

The Pidcock Creek drainage basin is located east of Doylestown in Bucks County and is bounded on the southwest by the southeast and south oriented Mill Creek drainage basin, the northwest by Buckingham Mountain, the north by Solebury Mountain, the northeast by the southeast oriented Delaware River, and the south and southeast by Bowman Hill […]
Northeast oriented Aquetong Creek headwaters originate north and east of Lahaska, Pa area and eventually reach the south oriented Delaware River while south and south-southwest oriented Lahaska Creek flows just west and south of Lahaska to reach Mill Creek and then Neshaminy Creek, which eventually flows to a southwest oriented Delaware River segment. Through valleys […]
The Delaware River flows in a south and southeast direction to Bulls Island and then turns to flow in an east-northeast direction for approximately one mile to Hendrick Island before turning to again flow in a southeast and south direction. Delaware River tributaries from the northeast are aligned in a southwest direction while tributaries from […]
The Delaware River-North Branch Neshaminy Creek Plumstead Township through valley extends in a southwest direction from Point Pleasant along the Delaware River to southwest oriented North Branch Neshaminy Creek, which at Chalfont joins east and southeast oriented Neshaminy Creek as a barbed tributary. Geddes Creek and a tributary drain the through valley northeast end. Geddes […]
The Core Creek Elbow of Capture east of Newtown, PA poses an intriguing problem as Core Creek first flows in a southeast direction toward the nearby Delaware River and then abruptly turns to flow in a southwest direction to eventually join Neshaminy Creek. Further shallow west-southwest to east-northeast oriented through valleys link the southeast and […]
Aligned and barbed tributaries are commonly found along south and southeast oriented Delaware River valley segments marking the Pennsylvania and New Jersey border. One such region is the New Hope, PA and Lambertville, NJ region where the Delaware River flows in a southeast and south direction as seen in figure 1. Most tributaries from the […]
The Delaware River flows in a southeast direction to the Washington Crossing area and then gradually turns to flow in a south-southeast direction. As seen in figure 1 closely spaced and aligned southwest oriented tributaries enter the Delaware River from the New Jersey side (east). Also as seen in figure 1 many streams from the […]
The Delaware River flows in a southwest direction along the Pennsylvania-New Jersey border until it turns to flow in a south direction under the Benjamin Franklin Bridge, which links the Philadelphia City Center with the Camden City Center. The abrupt change in the Delaware River direction of flow just north of the Benjamin Franklin Bridge […]
