Gulph Creek originates at an elevation of 410 feet in
Strafford, Chester County and flows east into Delaware County. Another branch begins in
Tredyffrin Township, Chester County, and flows south. The branches merge in
Radnor Township, Delaware County, just west of
Eastern University. The creek flows east through the campus, then turns northeast as it approaches East County Line Road. It enters
Montgomery County and continues northeast, before turning north to flow through the "gulph," a
gorge flanked by 200-foot hills. North of the "gulph" the creek turns east and flows through
Gulph Mills and the borough of
West Conshohocken, where it empties into the Schuylkill River. As it flows through the "gulph," Gulph Creek parallels
PA Route 320 and passes
Hanging Rock, the ancient remnant of a collapsed
natural arch. ==References==
