The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America. The Last Glacial Period caused a much lower global ...
The most recent glacial cycle, the Wisconsin Glaciation, began about 31,500 years ago and receded from the state by around 7,000 years ago. During this time the Lake Michigan Lobe and the Green Bay Lobe moved across the state; also present were the Chippewa, Superior, Wisconsin Valley, and Langlade lobes.
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
The buried forest has attracted attention for years, as seen in this Schumann photo from August 1967. A buried forest on the Lake Michigan shore at Two Creeks, trapped between two glaciers in the ...
Horicon Marsh was created by the Green Bay lobe of the Wisconsin glaciation during the Pleistocene era. The glacier, during its advance, created many drumlins (a glacial landform) in the region, many of which have become the islands of Horicon Marsh. The marsh and surrounding Dodge County have the highest concentration of drumlins in the world.
The different regions are defined by the differing effects of glaciers during the Wisconsin glaciation. [18] Timms Hill is the highest natural point in Wisconsin at 1,951.5 ft (594.8 m); it is located in the town of Hill, Price County. In the north, the Lake Superior Lowland occupies a belt of land along Lake Superior.
The moraine was created when the Green Bay Lobe of the Laurentide Ice Sheet, on the west, collided with the Lake Michigan Lobe of that glacier, on the east, depositing sediment. The western lobe formed Green Bay, Lake Winnebago and the Horicon Marsh. The major part of the Kettle Moraine area is considered interlobate moraine, though other types ...
Devil's Lake State Park is a state park located in the Baraboo Range in eastern Sauk County, just south of Baraboo, Wisconsin.It is around thirty-five miles northwest of Madison, and is on the western edge of the last ice-sheet deposited during the Wisconsin glaciation. [2]
