The Laurentide Ice Sheet On Minnesota's Landscape

Improved Essays
Did you know that only 10% of the world is covered by glaciers? The Laurentide ice sheet was 13 million square miles. And it shaped Canada and Minnesota. In this paper, I will explain the effects of the Laurentide ice sheet on Minnesota's landscape.

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,

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

    Glaciation had four major effects on Connecticut. The first one is Jobs pond, a kettle hole. A kettle hole is a chunk of glacier that broke off and sat in one spot. The glacier melted and created a pond ( Jobs pond). However there is no tributaries coming in or out of this pond so the only other source to get water is precipitation.…

    Annette Atkins is an American author and historian. Her book, published in 2007, is entitled “Creating Minnesota; A History from the Inside Out.” The history book gives an in depth look into the history of Minnesota from its very beginnings. She begins her narrative of Minnesota with the glaciers moving across it, leaving in its wake a fertile land. She moves on from this to the first Indian inhabitants, all the way to the time of Hubert Humphrey.…

    It then moved to the other state borders where the river ran through their land towards the Mississippi River. The headwaters of the river were supposedly in Blowing Rock, North Carolina. The river then flowed into most of the rivers surrounding us today. The river back then was used a draining basin for the eastern part of US. Due to the river and glaciers during the ice age, a few lakes were formed such as Lake Tight and Lake Monongahela along the boundaries of the Teays River.…

    Yosemite National Park, located in the central eastern portion of California, has been founded since 1890. The park is known for its natural habitats and abstract scenery. Tourist enjoy hiking in Tuolumne Meadows, lodging in Yosemite Valley, fishing in the Eastern Sierra and even skiing in the Mammoth Lakes mountain resort. But what any do not know is that all of these attractions were created by one phenomenon, glaciation.…

    (Perrapirce et al. 2010). Glacier retreat in Saskatchewan left behind sediments that formed rolling glaciofuvial silts and sands, flat glaciolucutrine clays, and hummocky till (Pennock et al. 2011). In small pockets of southern Saskatchewan, the parent material was influenced from melting glaciers whose melt water formed streams and large glacial lakes (Perrapirce et al. 2010). Larger sediments such as sand and gravel from the glacial melt water were deposited first in the stream delta forming rolling glaciofuvial silts and sands (Anderson and Cerowiak 2010). After the glacier retreat, these landscapes were impacted by wind erosion and formed aeolian deposits such as sand dunes and silty deposits (Perrapirce et al.…

    The Valparaiso moraine is a terminal moraine formed from the Lake Michigan lobe of the Laurentide Ice Sheet that spreads across Illinois to Michigan, ranging from 700 to 800 feet above sea level on average, with some hills topping 950 feet (Hartke, 1975). Although the whole segment is termed the “Valparaiso moraine,” it is more accurately the accumulation of several different moraines formed on top of each other, and the whole section has varying compositions and features. This suggests it wasn’t made in a single retreat, but rather a repeated advance and retreat of the glacier. There are two main till layers, which are primarily silt-clay loam and are separated by a discontinuous layer of sand and gravel outwash. On the western side of the…

    These systems consist of roughly 60% of water. If they are not 100% water, then what are they? The answer is humans. Humans have an astonishing impact on how Michigan shapes itself. Manufactured objects, such as dams, and reservoirs, can create a stronger flow or cut of a certain river and direct it in a different direction.…

    The entire land of all the islands is about 205 acres. The Islands were formed from a large glacier that left a very large, deep pocket of water. The evidence of a glacier is all over the islands. There are grooves and scratches in the solid rocks and glacial boulders that dropped on the islands from when the ice melted. Lastly, the levelled slope of the northern shores and the ragged cliffs in the south east resembled the effects of the glacier.…

    Several melts over a period of time created passageways, and evidence from archeological site implies that there was an ice-free corridor for thousands of years. It was during another melt approximately ten thousand years ago, that a second corridor was most likely formed farther east along the borders of Saskatchewan and Canada plains. This points to the possibility that the ancient people could have traveled eastward along the rivers in the Great Plains, and down further…

    Ice sheets still move along the land by the power of gravity. Along the way the glacier picks up very large boulders which are dragged along by the glacier and cut deep into the earth’s surface. “Common all over the world, glaciated valleys are probably the most readily visible glacial landform. Similar to fjords, they are trough-shaped, often with steep near-vertical cliffs where entire mountainsides were scoured by glacial movement. One of the most striking examples of glaciated valleys can be seen in Yosemite National Park, where glaciers literally sheared away mountainsides, creating deep valleys with vertical walls.”…

    Results showed that underlying the fastermoving areas of ice was a wet mud and gravel slurry not found in other areas, perhaps from an old stream bed, that provided lubrication for the ice above it. Using the scientific method can sometimes be complicated for geologists because Earth is their laboratory and it has many variables and is NOT a controlled environment. Controlled experiments (usually carried out in laboratories) are carefully designed to test a specific hypothesis, and they can be repeated. Unfortunately, many hypotheses in geology cannot be directly tested in a controlled experiment (e.g., the origin of the Grand Canyon cannot be discovered by using this approach). Geologists must collect data by mapping or collecting specimens.…
