Summary:"There are many glaciers all over Alaska. Flying into Lake Clark National Park and Preserve through Lake Clark Pass, you will see many glaciers. These glaciers were growing during the last Ice Age. Now many are retreating because Alaska is getting warmer. As the glaciers melt they leave behind evidence of their presence. The evidence includes moraines, erratics, and U-shaped valleys. The weight and movement of glaciers has a changing effect on the landscape. They pick-up rocks, scour out canyons, and push rock debris in front of them as they are growing or flowing. When the glacier is retreating it leaves behind large rocks and boulders known as erratics. It leaves behind a terminal moraine where it stops. Glaciers can create lakes, valleys and areas known as kettle marshes. Their weight and movement are the tools a glacier uses to shape the landscape. Use this experiment to look at small """"glaciers"""" and how they shape the landscape around them. You will be able to describe how a glacier carves an area and label the characteristics formed by the glacier's movement. By mixing water, rocks, and gravel and freezing it, the thaw will show imprints left behind by a """"glacier."""""
