Glaciers may seem irrelevant to how we live now because in Minnesota there hasn't been a glacier for a long time but, they formed our state. The last glacial advance start of the Des Moines lobe was about 75,000 years ago. The last glacial maximum which means most ice, was around 14,000 years ago, and it completely melted in Minnesota approximately 11,000 years ago. The Glacier moved south to about the middle of Iowa, and cover northern and western parts of Minnesota. It also covers the eastern North and South Dakota and ends in Iowa. Continental glaciers form by snow staying in the same spots all year and compacting and they keep growing, …show more content…
These lakes formed from the melting of these huge glaciers. Glaciers can create Kettles which are holes left behind after being pressured by a glacier that can fill with water. Glaciers can create huge lake like Lake Superior, which is a great example of evidence that glaciers have been in our state. There were many lakes like Lake Superior that has drained and they don't exist now but there names are lake Benson, lake Uham, lake Aitkin, lake Minnesota, Lake Grantsburg, Lake Duluth now know at Lake Superior and the largest lake, Agassiz. It went all the way into Canada. Lake Agassiz drained from the Mississippi River, Hudson bay, and the largest amount of water into lake Superior. There were many present day effects of Agassiz such as Glacial plains, Lake Winnipegosis, Lake Manitoba, and Lake of the Woods. The Laurentide ice sheet had a huge effect on Minnesota's Geology and if it weren't for glaciers we might not be able to claim our name of the land of 10,000
