“…In spite of the broad knowledge that river systems and drainage basins have changed significantly since the LGM (Upham, 1883;Bell, 1889;Clayton and Moran, 1982;Dyke and Prest, 1987;Wright, 1987;Teller, 1990a, b;Marshall and Clarke, 1999;Patterson, 1997Patterson, , 1998Licciardi et al, 1999;Overeem et al, 2005;Tarasov and Peltier, 2006;Wickert, 2014;Ullman et al, 2014;Margold et al, 2014;Ullman et al, 2015;Margold et al, 2015), many studies do not include any clear picture of drainage basin evolution. This results in representations of the modern drainage network wholly or partially in place of glacial-stage drainage basins (e.g., Blum et al, 2000;Sionneau et al, 2008;Montero-Serrano et al, 2009;Sionneau et al, 2010;Kujau et al, 2010;Lewis and Teller, 2006;Tripsanas et al, 2007Tripsanas et al, , 2014Rittenour et al, 2003Rittenour et al, , 2005Rittenour et al, , 2007Knox, 2007) that help to propagate a lack of consciousness about the continental-scale hydrologic changes that occurred, even in cases when the study acknowledges in the text that past drainage pathways were different. The best current Cenozoic history of Mississippi River drainage does not attempt to place its northern drainage basin boundary during the Pleistocene (Galloway et al, 2011).…”
