Analysis: The Wisconsin Glaciation Of Minnesota

The Wisconsin glaciation started in Minnesota about two million years ago. The parts missed by the Wisconsin glaciation were the Southwestern and Southeastern corners of Minnesota. There are four lobes in Minnesota called The Rainy Lobe, The Superior Lobe, The Des Moines Lobe, and The Wadena Lobe. The Wadena lobe advanced from Northern Minnesota. The Rainy Lobe along with the Superior Lobe advanced from Northeastern Minnesota.

Much of Michigan’s landforms can be traced to the Pleistocene period, which lasted until around 10,000 years ago. Of the four periods of glacial movements in the Pleistocene period, the Nebraskan, Kansan, Illinoian and Wisconsin, the Wisconsin Glaciation is the most prominent cause of the current Michigan landscape in the Upper Peninsula and Lower Peninsula (Damery, 2001). The Wisconsin Glaciation occurred about 100,000 years ago. The climate cooled, and the Laurentide Ice Sheet was spread across the continent. About 31,500 years ago, this glacier began to approach Wisconsin. The Laurentide Ice Sheet expanded in the area that today is Wisconsin and Michigan, for 13,500 years before the ice began to melt and retreat. As this ice sheet moved south, valleys were filled in, the drainage systems of rivers were blocked, and major basins that are now the Great Lakes were gouged. The graphic below shows the land that the Laurentide glacier

The glaciation is very confusing to those who don't know about glaciers so here is some background information. The last glacial advance started about 75,000 years ago and the last

In the 1920’s, geologist J. Harlen Bretz challenged the current concept of how various geological formations happened. At the time, geologists believed in uniformitarianism, which meant that geologic change in the past resulted from the same slow, steady processes at work today.

Arriving in the overgrown drive way trees start to crowd your vision, in the middle of all the trees I see an old beach house; that has stayed the same over the 18 years I have been going up there. Grandma is waiting outside on the front porch we all run up to give her a hug, then we go and start unpacking for a week’s worth of relaxing. First thing we do when were done unpacking is go to the old but new play structure. We sit on the swings and look out towards the big blue Michigan Lake. White caps cover most of the water along with passing boats, and some kayakers. Right over the horizon I can see the lights from the town, reaching into the sky. The sun is starting to set; the sky is painted with pink, orange, and yellow.

The first glaciers circulated south from what is now Canada. From what I’ve researched the Great Lakes were once riverbeds, which provided the glaciers perfect passage to the south.

Richard White provides a refreshing perspective on the Great Lakes region during the colonial and early national periods in regards to the developing relationships between the intrusive French, British, Americans and the indigenous Native Americans. The Middle Ground: Indians, Empires and Republics in the Great Lakes Region effectively links Native American history to broader themes in American history. He presents a convincing argument of how the Middle Ground, a place the French called the pays d’en haut, allowed for mutual accommodation and an acculturative social solution to develop out of the misunderstandings and the new meanings given to older institutions. White looks to this area to show how Native Americans and Europeans together constructed a complex and dynamic world that became the multiethnic society of early America. White has written a remarkable book that further enriches the historiography of the Great Lakes region and gives us a fuller understanding of this complicated world that underwent profound historic change.

The 1989-1991 Biennial Budget established a program that would support school districts’ efforts to give information about Wisconsin Indian history, culture, and tribal sovereignty. The exact year Act 31 took place was 1989 (information from Act 31 handout/lecture). I would like to teach at the high school level which is the grades nine through twelve. One course would be history. History is a very delicate topic when dealing with Wisconsin Native Americans. I would talk to the Native American students in my class, and I would ask them what they would be comfortable with me teaching. If those students could not make up their mind, then I would talk to their parents. I would also talk to the other history teachers and see what their

The Little Bison Basin has a relatively new history shrouded in mystery and revealed through its many glaciers and carved out regions. Prior to and into the ice age, this entire region was a frozen wasteland, lifeless and barren. In fact, it was so barren that no people had even ventured into the area.

The Paleo-Indian Tradition was considered the first humans to come to Wisconsin. Through the Bering Land Bridge, these people came into North America. They inhabited Wisconsin from 10,000-8,500 BC according to the Milwaukee Public Museum website.

A glacier occurs when the climate of an area is so cold that new snow does not completely melt each summer and more snow is added in the winter. After many winters the accumulation of this snow becomes compact and re-crystallizes, thus forming a glacier. Currently, glaciers cover about ten percent of the Earth's surface. Yet, in the past, glaciers covered much more land and were thousands of meters thick. (Tierney)

1. Michigan. I would choose Michigan for many reasons. For example, Michigan isn't along any tectonic plates. Plus, Michigan has not had any real damage earthquakes and it doesn't have any volcanoes. If you didn't want any part in any of that, then Michigan is the perfect place for you.

Wisconsin contains rocks ranging from around 359 million years all the way to 2.8 billion years old. Fortunately, this wide range of rocks has patterns in their placement across the state. If one were to dig down to solid rock, in general, the age of upper most rocks layers increases in age going from west to east, and also from south to north. The history of the formation of Wisconsin to its present day condition happed through major geological events such as various tectonic processes, sedimentation, metamorphism, and glaciation. Let’s walk through the major events that have come to define Wisconsin geology. The oldest rocks in Wisconsin are in the northern most part of the state near Ontario and they range from 2.8-1.0 billion years old. These rocks formed when North American continents was getting assembled, mostly though complex

Neoproterozoic ice ages: During these ice ages, two major glaciers were formed. One of which was formed before 600 Ma, and the

A glacier is a slowly moving mass of ice formed over years by the buildup and compaction of snow on mountains or near the poles. Most of the world's glaciers are found near the poles (because the very cold and snowy conditions found there) but glaciers actually exist on all the continents including africa! The perfect conditions to form glaciers are mostly found in regions with high snowfall in winter and cool temperatures in summer. These conditions allow snow to build up in winter and not melt in summer these conditions usually occur in polar regions and high alpine regions. Global warming is the gradual increase of the earth's atmosphere from carbon dioxide emissions from burning fossil fuels. Unfortunately the spreading disbelief of global
