Canerod--You may well be right, but even if that was the case the changes they would have wrought to areas a few hundred miles south would have been immense. I'm sure there's detailed information on how far they went somewhere (perhaps even in a book entitle The Geology of I-40 in a series I edited) but I'm not sure beyond that.
Just checked and the Park Service's website says the glaciers affected the Park without reaching it.
