  2. Last Glacial Period - Wikipedia

    en.wikipedia.org/wiki/Last_Glacial_Period

    The Wisconsin glacial episode was the last major advance of continental glaciers in the North American Laurentide ice sheet. At the height of glaciation, the Bering land bridge potentially permitted migration of mammals, including people, to North America from Siberia. It radically altered the geography of North America north of the Ohio River.

    Glacial history of Minnesota; Glacial period – Interval of time within an ice age that is marked by colder temperatures and glacier advances; Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago)

  4. Laurentide ice sheet - Wikipedia

    en.wikipedia.org/wiki/Laurentide_ice_sheet

    The Laurentide ice sheet (LIS) 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, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.

    Boulder Glacier, Mount Baker. There are around 880 glaciers in Washington state, with 186 named according to the Geographic Names Information System (GNIS). [6] However, the 1980 eruption of Mount St. Helens eliminated nine of its eleven named glaciers and only the new glacier known as Crater Glacier has been reestablished since.

  6. Cordilleran ice sheet - Wikipedia

    en.wikipedia.org/wiki/Cordilleran_ice_sheet

    The rapid retreat of the Cordilleran ice sheet is a focus of study by glaciologists seeking to understand the difference in patterns of melting in marine-terminating glaciers, glaciers whose margin extends into open water without seafloor contact, and land-terminating glaciers, with a land or seafloor margin, as scientists believe the western ...

  7. Wisconsin glaciation - Wikipedia

    en.wikipedia.org/wiki/Wisconsin_glaciation

    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 sea level. This glaciation radically altered the geography north of the Ohio River, creating the Great Lakes.

  8. Yarmouthian (stage) - Wikipedia

    en.wikipedia.org/wiki/Yarmouthian_(stage)

    Elsewhere in North America, as in Illinois, the Yarmouth Soil also has developed over a variable number of multiple glacial - interglacial cycles. [ 4 ] [ 8 ] Thus, the presumption that the Yarmouth Soil, by which the Yarmouthian (Yarmouth) Interglacial was later defined, represents a single interglacial stage or period has been completely ...
