The Wisconsin Glaciation Of Minnesota Many many years ago glaciers covered the northern half of the United States with ice. 75% of Minnesota was engulfed with thick moving ice, commonly known as the Des Moines Lobe. The Des Moines Lobe caused the Wisconsin Glaciation of Minnesota and shaped it into the wonderful state we know today. The Wisconsin Glaciation Of Minnesota constructing and destructing the landscape in Minnesota forever. Minnesota once had a glaciation period in the last ice age that molded it into many ways. This was called The Wisconsin Glaciation Of Minnesota and it started around 75,000 years ago. And 14,000 years ago Minnesota was at its last glacial maximum. But only a short 3,000 years later, it receded back into Canada to the quickly melting Laurentide Ice Sheet. The Des Moines Lobe reached as far down as Des Moines Iowa, and covered the northern and western parts of Minnesota. This particular Lobe was approximately 400 miles long and 50 miles wide. The Des Moines Lobe was made when snow compacted over hundreds of years. Some of …show more content…
Glacial lakes can be formed when a glacier carves a hole into the earth and then it fills with melt off. Or a chunk of ice breaks off and sinks into the ground, melts then you have a kettle lake. Evidence of a glacial lake would be Lake Superior, this massive lake was formed when glacial melt water flooded the Superior basin created by a glacier. As soon as the the majority of the Louritide Ice sheet melted, the water was stored in large lakes. Some of these lakes were Lake Agassiz and Lake Upham. Out of all the lakes there once were in Minnesota Lake Agassiz was the largest of them all with 170,000 square miles of water. Eventually this massive lake was drained by The Glacial River Warren left behind the Minnesota River, a tributary of the Mississippi. Some lakes remain from Lake Agassiz such as Lake Mille
