I don’t know how anyone would know but I have heard that there was three miles of ice above the Rockies. When you look at something like the Diamond on Long’s Peak and think about what it took to shear that off like a flint knapper taking a flake off of a piece of stone it has some credibility. But I don’t know how it really was. I do know that it would only take about 40’ of snow to cover up every stick of firewood around. Solid ice and high winds. Brrrr!

I did some googling and confirmed that in the West the ice stopped at about the Canadian border. There was substantial glaciation in the high mountains, but I couldn't find anything as to thickness. You see a lot of evidence of glaciation in Rocky Mountain National Park.

It's speculation on my part, but I would really doubt they were three miles thick, especially where the plains and mountain valleys were ice-free.

Still, the slogan "tis a pleasure to live in Colorado" probably wouldn't have been coined during the last glacial max. :-))
