Introduction: Sandy Run is an interesting secondary drainage route as it drains the Chester Valley east end (also known as the Roslyn Valley) in a west-southwest direction, but instead of continuing a short distance further on the Chester Valley floor to join south oriented Wissahickon Creek, it turns in a north direction to flow through […]

Overview: Along its 34.4-mile trip from Center City Philadelphia to Doylestown a SEPTA train travels from the Philadelphia City Center to and then along the Coastal Plain-Piedmont Province boundary before moving from the Coastal Plain onto the Piedmont to reach the Tookany Creek drainage basin. Once in the Tookany Creek valley the train travels in […]
Little Neshaminy Creek originates as a northeast oriented stream and then turns to flow in an east, southeast, and east direction to eventually join southeast and south oriented Neshaminy Creek, which then flows to a southwest oriented Delaware River segment. Wissahickon Creek originates as a southwest oriented stream just north of the northeast oriented Little […]
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 […]
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 […]
Without question the deepest, longest, and most magnificent Wissahickon Creek water gap is the seven-mile long Wiisahickon Gorge eroded across a 420-foot high ridge of tightly folded metamorphic and igneous rocks and which is located entirely within the Philadelphia city limits. The erosion resistant ridge extends in an east-northeast direction across southeast Pennsylvania and is […]
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 […]
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 […]
The Andorra Wind Gap links an east-northeast oriented tributary to the Wissahickon Gorge north entrance with a west-southwest oriented Schuylkill River tributary and has an elevation of 266 feet. To the south Schuylkill River-Wissahickon Creek drainage divide elevations rise to 420 feet before decreasing until Wissahickon Creek joins the Schuylkill River. To the north a […]
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 […]
The Marble Hall Through Valley between Spring Mill Creek and Wissahickon Creek is one of several through valleys linking the Wissahickon Creek valley upstream from the Wissahickon Gorge with the Schuylkill River valley and is located in Marble Hall between Lafayette Hill and Barren Hill. Wissahickon Creek flows in a south direction at the through […]
The Whitemarsh Through Valley between Plymouth Creek and Wissahickon Creeks is one of several low elevation through valleys linking the Wissahickon Creek valley upstream from Wissahickon Gorge with the Schuylkill River and is a west to east oriented valley underlain by easily eroded bedrock and bounded on the south by an erosion resistant upland and […]
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 […]
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 […]
Wissahickon Creek has a relatively small drainage basin in southeastern Pennsylvania, but is located along the Schuylkill River-Delaware River drainage divide southern end and includes a well-known and picturesque gorge in northwest Philadelphia. The stream rises near Lansdale in Montgomery County and flows for approximately 23 miles in a south direction to reach northwest Philadelphia […]
