Upper Wisconsinan  

Définition

  • Two related movements have been termed Wisconsin : Early Wisconsin and Late Wisconsin. The Early Wisconsin was the bigger of the two and extended farther west and south. It retreated an unknown distance before halting. During this period of quiet, the glacial deposits were eroded and weathered. This first Wisconsin period erased all the Illinoian glacial topography that extended over. The Late Wisconsin ice sheet extended more towards the west than the earlier movements. This may have been due to changes in the accumulation center of the ice sheet, topographic changes introduced by the Early phase or by pressure changes in the ice mass in the north. The culmination of Late Wisconsin is dated to 50,000 years before Present. (Adapted from: https://en.wikipedia.org/wiki/Wisconsin_glaciation)
