University Libraries Faculty Publications
Ridley Creek is a 24-mile long tributary of the Delaware River located in southeastern Pennsylvania. Its geological history has determined the topography of its watershed. The rolling Piedmont hills along most of its length, and the flat Coastal Plain at its confluence with the river have profoundly influenced the history of human land use within this landscape.
