Valley Creek originates as a north oriented stream along the Chester Valley south wall and turns in an east-northeast direction to flow along the Chester Valley floor, but before reaching the southeast oriented Schuylkill River turns in a north direction to cross the Chester Valley north wall between Mount Joy and Mount Misery and to […]

This inventory identifies most of each township’s obvious barbed tributaries and elbows of capture as seen on 1:24,000-scale United States Geological Survey topographic maps, but should not be regarded as being complete. Also many of the barbed tributaries and elbows of capture are best seen and understood by observing the evidence in an area much […]
The Schuylkill River between Phoenixville and Norristown makes several remarkable direction changes including two complete U-turns just upstream from Valley Forge National Historical Park. Other interesting Schuylkill River U-turns or perhaps incised meanders are found between Pottstown and Phoenixville, although this essay will focus on the U-turns between Phoenixville and Valley Forge National Historical Park. […]
West of the City of West Chester, Pennsylvania the East Branch Brandywine Creek flows in a south-southeast and southwest direction to join southeast, northeast, and southeast oriented West Branch Brandywine Creek and to form southeast oriented Brandywine Creek. Broad Run is a southeast, east, and south-southeast oriented West Branch Brandywine Creek tributary located between the […]
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 […]
Watson Creek is a relatively minor stream located east of Doylestown and flows in a south and northeast direction to join southeast oriented Mill Creek, which then joins southeast and south oriented Neshaminy Creek. In its short distance Watson Creek passes through two water gaps and abruptly changes direction at an elbow of capture. The […]
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 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 […]
A shallow (20-40 foot deep) through valley at location 1 (in figure 1) and shown in more detail in figure 2 (at end of text) links the south and south-southeast oriented Ironworks Creek valley head with a northeast oriented valley (Potter Run) draining through Northampton Country Club and Tyler State Park to southeast and south […]
The Neshaminy Creek drainage route just downstream from Neshaminy Falls exhibits an intriguing elbow of capture seen in figure 1 below. Neshaminy Creek flows in a south, southwest and south direction from location 1 to location 2 and then turns to flow in a northeast direction before turning again to flow in a southeast direction […]
The Neshaminy Creek drainage route north and west of Langhorne exhibits several intriguing elbows of capture. Figure 1 below shows Neshaminy Creek flowing in a southeast direction to Bridgetown (near map northeast corner) where it then makes a U-turn to flow in a west-southwest direction to Playwick Park (near map center). East-northeast oriented Mill Creek […]
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 […]
Spring Mill Creek (also known as Spring Mill Run) is a relatively minor Schuylkill River tributary and flows in a southwest, south, west, and south direction to the Schuylkill River at Spring Mill (just east of Conshohocken). The Spring Mill Creek drainage basin is bounded on the north and west by the southwest and south […]
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 […]
The Schuylkill River flows in a southeast direction into Philadelphia and just after flowing under the Roosevelt Avenue Bridge makes an abrupt turn to flow in a southwest direction. After flowing in a southwest direction the Schuylkill River flows under the Columbia Bridge and just west of the East Park Reservoir makes another abrupt turn […]
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 […]
After flowing in a southwest, south, south-southeast, and east direction Wissahickon Creek turns at its Gynedd Valley Elbow of Capture to flow in a south direction through its Gynedd Valley Water Gap. Southwest and west-southwest oriented Trewellyn Creek joins the east oriented Wissahickon Creek segment at the Gynedd Valley Elbow of Capture. The Gynedd Valley […]
Sandy Run originates in Roslyn and flows in a west direction along the Camp Hill ridge south flank or the Whitemarsh Valley north side toward the south oriented Wissahickon Creek, but instead of continuing in a west direction Sandy Run turns abruptly at the Sandy Run Elbow of Capture to flow in a north direction […]
Two adjacent water gaps can be seen just south of Fort Washington. The first, the Wissahickon Water Gap, is where Wissahickon Creek flows in a south direction between Fort Hill (east) and Militia Hill (west). The second, the Sandy Run Water Gap, is where Sandy Run turns from flowing in a west direction to flow […]
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 […]
