| 6 | Esker |
| Eskers are long, winding ridges of stratified sand and gravel which occur in glaciated and formerly glaciated regions of Europe and North America. They are frequently several miles in length and, because of their peculiar uniform shape, somewhat resemble railroad embankments. Eskers are the ... | |

| 10 | Ice Age Trail |
| The Ice Age Trail is a designated National Scenic Trail in the United States that will run some 1000 miles through the state of Wisconsin. In 2003, some 600 miles of trail is completed. The trail wanders through the state following the southernmost location of the last continental glaciation ... | |
| 11 | Nunatak |
| A nunatak is a mountain top that never has been covered by land ice (glaciation, ice age) or glaciers. The wildlife on a nunatak can be isolated by the surrounding glacier, just like an island in the ocean. The word is borrowed from inuit and has been used in west European languages at least since ... | |
