The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~ 2.6 million years. The ice sheet covered up to 2.5 million square kilometres at the Last Glacial Maximum and probably more than that in some previous periods, when it may have extended into the northeast extremity of Oregon and the Salmon River Mountains in Idaho.
