A minor nitpick, Winona, MN is part of the Driftless Area that was not covered by glaciers during the last ice age. It was definitely shaped by glacial meltwaters, though.

- doodlebugging 4y agoThank you for this. I did not know that part of Minnesota and Wisconsin have no evidence of glaciation from the last ice age. I imagine then that all the landforms are related to outflow of melt-water from the glaciers as they receded. I appreciate that information and for anyone else interested in glacial landforms I found a great Story Map to shows in DEM models and in photos what you would expect to see post-glaciation.
