Question

What are the names of the two glaciers that covered much of North America during the Pleistocene? And which of the two was the larger glacier?

Answer 1

I'm having difficulty finding these names. I seem to recall from Glacial Geology a Laurentide Ice Sheet and a Cordilleran Ice Sheet, however (both were still retreating when I was in grad school). The Laurentide sheet (if that was it's name!) was much the larger, covering much of North America, down to the Ohio River (across it, in some cases). The Cordilleran sheet (western NA) was amplified by numberous mountain or Alpine glaciers.

Answer 2

no clue but they might melt cuz of global warming! hah.

Answer 3

'Cold' and 'Colder'
