I, love it! How would a meteor, hitting a glacier and causing melt wash? I mention this because ive been rock hounding in blackhawk county and have found a layer of melted limestone with a layer of glass on top dark too light shades of green teals and greys n blacks. .... Im just saying it looks like a event of chunks of glacier flowing and the bits left were the inbetweens. I say Meteor and wind fill, over time.
Younger Dryas at the end of the last glaciation had 2 episodes triggered by cosmic impacts. A lot of the formations in Iowa, particularly the Missouri and Mississippi underfit river basins, where formed by the massive outwash of glaciers melted by these impacts.
Excellent interpretation. Thank you for your work.

Very interesting. Do you know if the Iowa glaciers formed in place by local snowfall or did the glaciers flow down from Canada?
Great lecture. Exactly what I was looking for. Thanks
