This paper reports on the landform assemblages at the northern confluence of the Late Wisconsinan Laurentide and Cordilleran ice sheets with montane and piedmont glaciers in the northern Rockies and southern Mackenzie Mountains. Recent observations in northeastern British Columbia refine our knowledge of the pattern and style of ice sheet retreat, glacial lake formation, and meltwater drainage ...

Actually, the terms Wisconsinan Glaciation or Weichselian Glaciation (NW Europe) are frequently used as general terms for the last glacial cycle sensus lato. However, this statement begs the question of when did the “Wisconsinan” Glaciation of North America really commence?

The Wisconsinan glaciation (red) peaked about 20,000 years ago. These glaciations had a major impact on Indiana geology. Glacial sediments buried much of the karst present in the older limestones north of these glacial boundaries.

Wisconsinan Glaciation. The last ice advance into Ohio, the Wisconsin Glaciation, began around 35,000 years ago and ended roughly 12,000 years ago, when ice retreated out of the Lake Erie Basin.

The extent of glacial erosion and volume of glacial deposition indicates that toward the northern border of Pennsylvania, Late Wisconsinan ice was present for 8,000 - 10,000 years, and lastedA late Wisconsinan marine deposit of nonglacial origin overlies the glaciomarine deposits in Cape Cod Bay. Both deposits indicate that the crust was isostatically depressed below the late Wisconsinan eustatic sea level and that deglaciation and marine submergence occurred simultaneously. Valleys cut into the marine deposits, both glacial and ...During this time, cyclic climate fluctuations caused glaciers and continental-scale ice sheets to advance and retreat into the mid-latitudes of the northern hemisphere.
