1 Fig. 2 Pleistocene drainage evolution in the upper Mississippi drainage basin.
Pleistocene drainage evolution in the upper Mississippi drainage basin. (A) The pre-Pleistocene continental divide extended from southern Wisconsin to southern Minnesota (30) and had been stable throughout the Cenozoic (101). The pre-LGM Mississippi River followed the course of the Illinois River over erodible shales; LGM ice advance pushed it into its current course (13). (B) Ice advance (drawn schematically; exact pattern unknown) dammed and rerouted former tributaries to the St. Lawrence, causing them to overtop and incise through the paleodivide (1). (C) Modern rivers and depth to bedrock data points. (D) Location map. In map (A to C) backgrounds, shading indicates shale (easily erodible), and carbonate bedrock underlies most of the paleodivide region (fig. S4). Andrew D. Wickert et al.
