Figure 3: Relationship of southwest oriented Wissahickon Creek headwaters to southwest oriented Towamencin Creek headwaters. West of map Towamencin Creek flows to south and southwest oriented Skippack Creek, which then flows to south oriented Perkiomen Creek, which in turn flows to the southeast oriented Schuylkill River. Southwest oriented Towamencin Creek headwaters along with the southwest oriented Wissahickon Creek headwaters are relics of the southwest oriented drainage routes that once crossed the region.
