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 ...
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 ...

Cordilleran Ice Sheet. Southern edge of the ice sheet. It extended north along the Pacific coast and covered the Alaska Peninsula. The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~2.6 million years.
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 ...
During the last glacial maximum, northern North America was covered by an ice sheet, which alternately advanced and retreated with variations in the climate.This continental ice sheet formed during the period now known as the Wisconsin glaciation, and covered much of central North America between 30,000 and 10,000 years ago.
The Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation ...
The Pleistocene (/ ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [ 5 ][ 6 ] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c.2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International ...
