The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. [2] Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth 's climate by ...
The last glacial period saw alternating episodes of glacier advance and retreat with the Last Glacial Maximum occurring between 26,000 and 20,000 years ago. While the general pattern of cooling and glacier advance around the globe was similar, local differences make it difficult to compare the details from continent to continent (see picture of ...
Laurentide ice sheet. The maximum extent of glacial ice in the north polar area during the Pleistocene period included the vast Laurentide ice sheet in eastern North America. The Laurentide ice sheet 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 ...
Timeline of glaciation. Appearance. Climate history over the past 500 million years, with the last three major ice ages indicated, Andean-Saharan (450 Ma), Karoo (300 Ma) and Late Cenozoic. A less severe cold period or ice age is shown during the Jurassic - Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth ...
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 glacial advance reached the Last Glacial Maximum about 26,500 BP. In Europe, the ice sheet reached Northern Germany. Over the last 650,000 years, there have been on average seven cycles of glacial advance and retreat.
Weichselian glaciation. The Weichselian glaciation is the regional name for the Last Glacial Period in the northern parts of Europe. In the Alpine region it corresponds to the Würm glaciation. It was characterized by a large ice sheet (the Fenno-Scandian ice sheet) that spread out from the Scandinavian Mountains [1] and extended as far as the ...
Last Glacial Period, not to be confused with the Last Glacial Maximum or Late Glacial Maximum below. (The following events also fall into this period.) 48,000–28,000: Mousterian Pluvial wet in North Africa 26,500–19,000: Last Glacial Maximum, what is often meant in popular usage by "Last Ice Age" 16,000–13,000
