| Coastal areas deglaciated rapidly as coastal alpine glaciers, then lobes of Cordilleran ice, retreated. |
| Local glaciations existed in the Rocky Mountains and the Cordilleran ice sheet and as ice fields and ice caps in the Sierra Nevada in northern California. |
| 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 Tapir Pinchaca appears to be confined to the region of the cordilleran table-lands. |
| The inland Cordilleran and Laurentide ice sheets retreated more slowly than did the coastal glaciers. |
| During the wet season the vicua browses on the scanty vegetation of the cordilleran ridges. |
