I understand that this is a C-Class article and would have some deficiencies. However, I see that the section "Sea Level During Glaciation", in my understanding, contains a significant lack of scholarship.

It is an accepted fact that during an Ice Age glaciers form, and as the result, sea level drops. The "Sea Level During Glaciation" section begins by stating that, "sea levels at the Last Glacial Maximum were over a hundred metres higher than they are today". Of course, there is no ready reference for this claim. In the second paragraph, there is a discussion about the sea level being lower with an explanation that is bewildering.

The third paragraph discusses how the migration from Beringia to North America was facilitated due to the subsequent deglaciation "due purely to the exposure of submerged land between the mainland and numerous continental islands". Logicaly, deglaciation would raise the sea level; deglaciation exposing land is not true.

The fourth paragraph is clearly non sequitur.

As a minimum, the third and fourth paragraphs should be eliminated.

Overall, this section does nothing to the purpose of describing the Cordilleran Ice Sheet. I suggest, lacking significant improvement, this section should be deleted.
