The Wisconsin Glacial Episode, also called the Wisconsinan glaciation, was the most recent major advance of the North American ice sheet complex. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide ice sheet. "Surficial geology" refers to the study of landforms and the unconsolidated sediments that lie beneath them. The majority of the unconsolidated sediments found at the land surface were deposited during the late Wisconsin glaciation, 21, to 13, years ago. Matthew Barnes, Claire L. McLeod, Caleb Chappell, Olivia Faraci, Brandt Gibson, Mark P. S. Krekeler, Characterizing the geogenic background of the Midwest: a detailed mineralogical and geochemical investigation of a glacial till in southwestern Ohio, Environmental Earth Sciences, /sz, 79, 6, ().Cited by: This was the beginning of the last major glaciation in Ohio. By ab years ago, the Wisconsinan glacier reached Ohio and by ab years ago, the ice had reached its maximum southward extent, covering nearly two-thirds of the state. As the climate once again warmed, the Wisconsinan glacier began to melt and retreated northward.

The age of Indiana’s bedrock that breaks the surface ranges between million and million years old. The Ordovician shale and limestone that occur as outcrops in the southeastern part of the state contain many fossils. The younger rock layers that are exposed in the southwestern region of the state. The glacier that began melt to 15, years ago was the last one of four to cover Indiana and has been named the Wisconsin glacier. The Saginaw lobe of this massive, one-mile thick, ice flow was the last of the “great forces” of Mother Nature to leave a . Start studying Glacial History of Wisconsin.

In ground water, arsenic is commonly present in two oxidation states. Arsenate (H n AsO 4 n-3) has an oxidation state of +5 and is the predominant form of arsenic in oxic te (H n AsO 3 n-3) has an oxidation state of +3 and is the predominant form in reducing the two forms, arsenite is the more toxic and the more mobile in solution.

  The Wisconsin Glacial Episode was the last major advance of continental glaciers in the North American Laurentide ice sheet. This glaciation is made of three glacial maxima (sometimes mistakenly called ice ages) separated by interglacial warm periods (such as the one we are living in). These glacial maxima are called, from oldest to youngest, Tahoe, Tenaya and Tioga. This was an increase in ground-water use of about 30 percent from (Southeastern Wisconsin Regional Planning Commission, ). During , for a seven-county area in southeastern Wisconsin, the majority of ground-water withdrawals (52 percent) were from the deep sandstone aquifer (Feinstein and others, ). Hydraulic Properties.   At acres, Falls of the Ohio State Park is the smallest of Indiana's state parks. The park resides in the town of Clarksville, Indiana just across the river from Louisville, Kentucky. The Falls of the Ohio were a series of rapids that allowed the river to fall 26 feet in a little over two and a half miles. The Wisconsin Geological and Natural History Survey (WGNHS) has been serving Wisconsin for over years. Part of the University of Wisconsin-Madison Division of Extension, we provide objective scientific information about the geology, mineral resources, and water resources of Wisconsin.
