Introduction: Gulph Creek is a Schuylkill River tributary located in the region where Chester, Delaware, and Montgomery Counties meet. Gulph Creek is only about six miles long from its head on the Schuylkill River-Delaware River drainage divide to its mouth where the creek flows into the Schuylkill River and drains an area of approximately six […]
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 […]
Two completely different Valley Creeks originate almost adjacent to each other in the South Valley Hills near Glenloch (between Malvern and Exton) and then flow parallel to each other in a north direction in deep narrow valleys down a steep slope onto the west-southwest to east-northeast oriented Chester Valley floor where the eastern Valley Creek […]
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 […]
A shallow, but interesting through valley crosses the Schuylkill River-Delaware River drainage divide at the Main Line community of Strafford and links east oriented Gulph Creek, which flows to the Schuylkill River, with south oriented Darby Creek tributaries, with Darby Creek eventually reaching the Delaware River. The drainage divide elevation at the Strafford through valley […]
A well defined northeast-to-southwest oriented through valley links the northwest oriented Deer Run valley with the southwest oriented East Branch Perkiomen Creek valley. The Deer Run valley drains to southeast, east, and south oriented Tohickon Creek, which flows to the southeast oriented Delaware River and the East Branch Perkiomen Creek drains to south and southwest […]
The Valley Forge National Historical Park is located south of a northeast oriented Schuylkill River segment and at the east-northeast end of the ridge forming the Chester Valley west-northwest margin. Mount Joy in the Valley Forge Park is where the high ridge ends and west of the Mount Joy the ridge segments are named Mount […]
The Chester Valley is a narrow lowland extending from near the southeast oriented Susquehanna River valley in an east-northeast direction almost to the southeast oriented Schuylkill River valley. The Pennsylvania Geologic Survey web applications map shows the Chester Valley to be underlain by easily eroded carbonate rocks. The Chester Valley north rim (North Valley Hills) […]
The Honey Brook basin as defined here is located between Welsh Mountain and the Baron Hills and serves as the headwaters region for the East and West Branches of Brandywine Creek, the South Branch of French Creek, and Pequea Creek with Brandywine Creek flowing to the Delaware River, French Creek to the Schuylkill River, and […]
Pequea Creek originates on the Welsh Mountain southeast flank and flows in a southeast direction before turning to flow in a west and southwest direction to eventually join the Susquehanna River. The West Branch Brandywine Creek also originates along the Welsh Mountain southeast flank, although east of the Pequea Creek headwaters, and flows in a […]
The Chester Valley between Parkesburg and Coatesville is an east-northeast oriented segment of a much longer through valley and includes the drainage divide between south oriented Buck Run at Pomeroy and south oriented West Branch Brandywine Creek at Coatesville. West Branch Brandywine Creek flows from the 600-700 foot high North Valley Hills (north of the […]
The Chester Valley between Coatesville and Dowingtown is an east-northeast oriented through valley linking south oriented West Branch Brandywine Creek with south oriented East Branch Brandywine Creek. West Branch Brandywine Creek flows from the 500-600 foot high North Valley Hills (north of the Chester Valley) to enter and cross the less than 350-foot high Chester […]
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 […]

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 Paunnacussing Creek-Pine Run Through Valley is located a short distance north and east of Doylestown and links northeast oriented Paunnacussing Creek drainage with southwest oriented Pine Run drainage. Paunnacussing Creek flows in a northeast direction to join the south oriented Delaware River as a barbed tributary. Pine Run flows in a southwest direction to […]
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 […]
Newtown Creek (location 2, 4, and 5 in figure 1) is a relatively minor stream flowing in a southeast, east-northeast, and south direction near and through Newtown, PA to join southeast and south oriented Neshaminy Creek south of figure 1 (Neshaminy Creek flows in a southeast direction from location 1 to the figure 1 south […]
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 Mill Creek-Southampton Creek through valley (illustrated in figure 1) links south-southwest oriented Southampton Creek (location 2), which flows to Pennypack Creek (seen in the figure 1 southwest corner), with southeast and east-northeast oriented Mill Creek (location 3), which flows to Neshaminy Creek (located east of figure 1). The deepest notch (location 1) has a […]
The Somerton-Huntingdon Valley Through Valley is a shallow west-southwest to east-northeast oriented continuous valley linking the south oriented Poquessing Creek valley (east) with the south oriented Pennypack Creek valley (west).
