Cordilleran Ice Sheet was located in North America.
The direction north is quite often associated with colder climates because most of the world's land at high latitudes is located in the Northern Hemisphere
== Sea levels during glaciation ==Because of the weight of the ice, the mainland of northwest North America was so depressed that sea levels at the Last Glacial Maximum were over a hundred metres higher than they are today (measured by the level of bedrock)
