Wisconsin Glaciation Effect
Wisconsin Glaciation Effects on Minnesota
A glacier is a large piece of ice on land, normally formed over time. A glacier forms when snow falls and compresses together to form the large mass of ice over time. The glaciers can move because of gravity, and the smoothness of the glacier. Glaciers were present in Minnesota thousands of years ago, and as they retreated they left behind large amounts of glacier meltwater and various landforms still present today.Glaciers are both constructive and destructive. The glaciers are constructive because glaciers pick up materials and sediments. Glaciers are destructive because glaciers tear down everything in the glacier's path. There were four lobes present in Minnesota with the names of Rainy lobe,superior lobe, Des Moines lobe, and Wadena lobe. These lobes all came from the south.The glacier moved as far south as Des Moines's Iowa. The southern parts of Minnesota along with the middle were missed by the ice. The start of the Wisconsin glaciation started in Minnesota 75,000 years ago. The ice went into Minnesota almost 14,000 years ago. Minnesota was ice free 11,000 years ago from today. Water from melting glacier/ice flooding a landscape forms a glacial lake. There …show more content…
were 5 glacial lakes located in Minnesota Grantsburg,Upham,Aitkin, Duluth, and Agassiz. The largest glacial lake formed in Minnesota goes by the name of the Agassiz lake, which form in northwestern Minnesota. The glacial river Warren drained the Agassiz lake. The present day river in place of the glacial Lake Agassiz, is Minnesota River. Till and outwash are very different.
Till has large sediments and no layers, outwash has small sediments and is in organized layers. Till and outwash are produced the same way which is deposited directly from melt water. Drumlins are elongated hills with one steep side, drumlins can be found in west-central Minnesota with the name of Wadena drumlin field. A moraine is a show path of where the glacier has been also called “footprints”. Moraines can be found in west-central, eastern, and central Minnesota. A kettle lake forms by ice breaking off of a glacier and forming a depression that fills with water. Most kettle lake clusters in Minnesota are located in central Minnesota.Outwash plains form when the glacier pushes small sediments in
front. In conclusions even though glaciers were present thousands of years ago there are still traces of them. Glaciers really are very interesting to study. Many things that were mysteries many years ago about glaciers we have discovered, some things are still to be discovered.
