Abstract

This review paper evaluates assumptions of pristine landscapes and European disruption from a geomorphic perspective, i.e., with regard to fluvial erosion and sedimentation rates. Geoarcheologic and sedimentologic evidence indicates that the potential for geomorphic change with land-use practices utilized by European settlers was potentially very effective in producing erosion and sedimentation in Anglo America (United States and Canada). A general lack of evidence of rapid sedimentation prior to the time of European contact implies that pre-Columbian agriculture was not highly disruptive geomorphically. Examples from northern California and the southeastern Piedmont support this interpretation by documenting geomorphically stable conditions followed by episodic fluvial sedimentation after colonization
