What was the Wisconsin Glaciation?
The Wisconsin glacial stage is the last glacial period of the Pleistocene in North America. It is an glacial period following the Sangamong interglacial period. To the south of the Great Lakes, about 40 ° north latitude, the total area is 16 million square kilometers, which is more than double the 6.7 million square kilometers of European glacier area in the same period. Compared with the modern Antarctic ice sheet (14 million square kilometers), Slightly bigger. The Wisconsin Glacial Laurent Ice Sheet has rapidly retreated from 14,000 years ago to 11,000 years ago and has retreated to the northern edge of the Canadian Shield. The entire Canadian Plain and Cordillera Ice Sheet have all disappeared 10,000 years ago. The water cover invaded Hudson Bay 8000 years ago. The ice sheet in the Fokker Basin has existed 7000 years ago, while the Ladorado ice sheet still has water rivers until 6500 years ago.

- The Wisconsin glacial chronological order has been divided into five subglacial periods from Lowan, Cary, Mankato, Valders, and Cochrane. . It is comparable to the Wilm Glacier in the European Alps and the Weissel Glacier in Northern Europe.
