This glaciation is made of three glacial maximums (commonly called ice ages) separated by interglacial periods (such as the one we are living in).
In the region of Bern it merged with the Aar glacier.
Montane and piedmont glaciers formed the land by grinding away virtually all traces of the older Günz and Mindel glaciation, by depositing base moraines and terminal moraines of different retraction phases and loess deposits, and by the pro-glacial rivers' shifting and redepositing gravels.

The Quaternary history of the Puget Lowland is marked by three early Pleistocene glaciations (the Orting, Stuck, and Salmon Springs, separated by interglacial periods represented by the Alderton and Puyallup Formations) and two pre-late Wisconsin glaciations (the Double Bluff and Possession, separated by an interglacial period represented by the Whidbey Formation).

According to a 1995 Wisconsin Department of Natural Resources report, "The greatest historical event impacting Wisconsin vegetation occurred 10,000-60,000 years ago when Wisconsin was invaded by continental ice sheets."

The Wisconsin (in North America), Weichsel (in Scandinavia), Devensian (in the British Isles) or Würm glaciation (in the Alps) is the most recent period of the Ice Age, and ended some 10,000 Before Present (BP).
In Scandinavia, only the western parts of Jutland (a part of Denmark) were ice-free during the glaciation and a large part of what is today the North Sea was dry land connecting Jutland with Britain.
The Baltic Sea, with its unique brackish water, is a result of meltwater from the Weichsel glaciation combining with saltwater from the North Sea when the straits between Sweden and Denmark opened about 7,000 BP.

During the late Wisconsin glaciation (circa 26,000-13,000 carbon-14 yr BP) the Cordilleran glacier complex formed vast ice fields and large glaciers along the crest of the Coast Mountains.
For instance, the glacier that extended into the Dixon Entrance trough is known to have extended to the edge of the continental shelf.
Previous studies suggested that during the late Wisconsin glaciation Cordilleran ice overwhelmed the Alexander Archipelago and terminated in one vast ice front at the edge of the continental shelf.

 AW2002 Abstract: Carrara
As these glaciers flowed west toward the Gulf of Alaska they were joined by local glaciers originating on the higher reaches of the islands of the Alexander Archipelago (Mann and Hamilton, 1995).
For instance, the glacier that flowed into the Dixon Entrance trough advanced to the edge of the continental shelf; its retreat began sometime after 15,000 to 16,000 BP and the trough was free of ice by 13,000 BP (Barrie and Conway, 1999).
Although the exact extent of the late Wisconsin glaciers in southeastern Alaska is poorly known, the new bathymetric map indicates that most late Wisconsin glaciers along the western edge of the Alexander Archipelago did not extend to the shelf edge as some previous studies suggested (e.g.

This is the world of the Wisconsin glaciation, the last ice age to occur in North America.
The glaciation that lasted from 70,000 years ago to roughly 10,000 years ago created an America that is so different as to almost be an alien land when compared to the modern landscape.

Wisconsin Glaciation and The Labrador Sector of the Laurentide Ice Sheet
As the ice sheets and glaciers waned and the land surface was uncovered, the forms implanted by the ice were left exposed or were covered by glacial debris waqshed out from the receding ice margins on land, in lakes or in the sea.
The complex record of glacial and postglacial features and deposits remaining today afford a means of tracing the paths of the receding ice margins and interpreting the deglacial and postglacial patterns.

A glaciation (a created composite term meaning Glacial Period, referring to the Period or Era of, as well as the process of High Glacial Activity), often called an ice age, is a geological phenomenon in which massive ice sheets form in the Arctic and Antarctic and advance toward the equator.
Conversely, the term interglacial or Interglacial Period, such as the current era, is used to denote the absence of large-scale glaciation on a global scale — i.e., a non-Ice Age.

The conclusion that early glaciations entered Wisconsin more than 700,000 years ago is based on lake and glacial sediment west of Eau Claire that has reversed magnetic polarity of lake sediment and till (Hersey and parts of the Kinnikinnic Members of the Pierce Formation (Baker, et al., 1994).
Although there is evidence of early Wisconsin ice advances farther east in Ontario, there is little evidence of the extent of isotope stage 3 or 4 ice in the western Great Lakes area.
That lack of evidence probably does not mean that glaciers failed to enter the region; rather, almost everywhere earlier deposits probably were mostly eroded and the remnants covered by younger materials laid down by the late Wisconsin glaciers.
