Thanks for the map. I’m in northeast Kansas, at the tip of the glacier. We have some pink granite stones in the area...geologist say it is the result of ‘glacial till’...or rocks from Wisconsin that were carried here by the glacier, and left behind when the glacier receded. They are rounded, after slowly rolling (at glacial speed) a thousand miles to get here. There is no pink granite anywhere in this area, so its pretty neat to think of the journey these rocks took to get here.
