Crum Creek and Darby Creek both originate in the same region near Paoli and Berwyn just south of the Chester Valley south rim and diverge slightly before flowing in southeast and south-southeast directions to join the southwest oriented Delaware River at almost the same location. Both streams are joined by northeast oriented barbed tributaries from […]

Cheney, PA is located in an east oriented East Branch Chester Creek valley segment and is located a short distance downstream from the confluence of south-southeast oriented East Branch Chester Creek with southeast oriented Goose Creek and a short distance upstream from where the East Branch Chester Creek turns to flow again in a south-southeast […]
Darby Creek flows in a southeast direction from near Berwyn and Daylesford, PA to southwest Philadelphia where it turns to flow in a southwest direction to join the southwest oriented Delaware River. Crum Creek headwaters are located just west of the Darby Creek headwaters near Paoli and Crum Creek flows in a south-southeast direction to […]
Figure 1 illustrates the drainage divide area at Chester Heights between Chester Creek and West Branch Chester Creek and also illustrates at locations 1 and 2 two well-defined gaps (or notches) linking northeast oriented tributary valleys with southwest oriented tributary valleys. Note how Chester Creek flows in a southeast direction from the north center edge […]
Ridley Creek flows in a south-southeast direction along the west edge of Media and eventually reaches the southwest oriented Delaware River while Chester Creek flows in a southeast direction approximately 3 kilometers to the west and independently reaches the Delaware River. In addition to being two closely spaced and roughly parallel southeast oriented Delaware River […]
Media (Delaware County, PA) is located on the relatively narrow drainage divide between south oriented Crum Creek and south-southeast oriented Ridley Creek. Northeast oriented and barbed tributaries drain to Crum Creek and to Ridley Creek from the west and tributaries to both creeks from the east are oriented in southwest directions. The northeast and southeast […]
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 […]
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 […]
Tacony Creek (known also as Tookany Creek further upstream and as Frankford Creek further downstream) flows in roughly a southeast direction from Elkins Park to between Cheltenham and Ashmead Village and then turns abruptly to flow in a southwest direction between Ashmead Village and Lawndale. This abrupt change of direction is here named the Cheltenham […]
The Schuylkill River Gorge, as defined here, extends in a southeast direction for about eight miles from Spring Mill (east of Consohocken) to the Roosevelt Avenue Bridge Elbow of Capture in the City of Philadelphia. While longer than the seven-mile long Wissahickon Creek Gorge the Schuylkill River Gorge is much wider and unlike the Wissahickon […]
Pennypack Creek as seen in figure 1 flows in a southeast direction from location 1 to location 2 with two noticeable northeast oriented turns and two noticeable southwest oriented segments. Tributaries from the east identified by locations 3, 4, 5, and 6 all flow in southwest directions to join south oriented Pennypack Creek segments at […]
The Schuylkill River flows in a south direction from Norristown to West Conshohocken where it turns to flow in an east-northeast direction to Spring Mill and then turns abruptly to flow in a southeast direction through the eight-mile long Schuylkill Gorge carved in erosion resistant metamorphic and igneous rocks. The gorge southeast end is in the […]
Wissahickon Creek flows through the Ambler region in a southeast direction before making a turn to flow in a southwest and then south direction through its Fort Washington Water Gap located between Militia Hill and Fort Hill. In the Amber region southeast oriented Wisahickon Creek is joined by southwest oriented tributaries from the east and […]
Wissahickon Creek flows in a southwest and south-southwest direction as it travels from its headwaters to just west of North Wales and then turns to flow in a south-southwest and south-southeast direction to pass through the first of several water gaps encountered on its journey to reach the southeast oriented Schuylkill River. South of the […]
Stony Creek flows in a southwest and south direction in Montgomery County to join the southeast oriented Schuylkill River at Norristown. Southwest oriented Stony Creek headwaters and headwaters tributaries are linked by shallow through valleys with the south oriented Wissahickon Creek valley to the east. Other Stony Creek tributaries flow in south, southwest, and northeast […]
Wissahickon Creek after flowing for approximately six miles in a south-southeast direction through the Wissahickon Gorge turns to flow in an east direction where it is joined by southwest oriented Monoshone Creek. But, instead of continuing in a south-southeast or east direction Wissahickon Creek makes an abrupt turn to flow in a southwest direction along […]
Wissahickon Creek originates near Lansdale at an elevation of approximately 400 feet and its headwaters flow in a southwest direction for a distance of approximately 4 miles before reaching an elevation of about 300 feet where the stream turns to flow in a southeast direction through its first water gap. Wissahickon Creek headwaters are bounded […]
Southwest oriented North Branch Neshaminy Creek and southwest oriented Pine Run join northeast oriented West Branch Neshaminy Creek at Chalfont to create the meandering and east oriented Neshaminy Creek, which eventually meanders in a southeast, south-southeast, and south direction to join a southwest oriented Delaware River segment. The Chalfont Elbow of Capture is just one […]
