During the wet season the vicua browses on the scanty vegetation of the cordilleran ridges. |
That led to the hypothesis of a migration route between the Laurentide and Cordilleran ice sheets to explain the early settlement. |
Mexico, unlike other cordilleran countries, lends itself to travel in certain directions by means of roads and vehicles. |
The lowered sea level, and an isostatic bulge equilibrated with the depression beneath the Cordilleran Ice Sheet, exposed the continental shelf to form a coastal plain. |
The Cordilleran ice sheet produced features such as glacial Lake Missoula, which would break free from its ice dam causing the massive Missoula floods. |
The inland Cordilleran and Laurentide ice sheets retreated more slowly than did the coastal glaciers. |
