  2. Pleistocene - Wikipedia

    en.wikipedia.org/wiki/Pleistocene

    The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -⁠stoh-; [4] [5] 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.

  3. Laurentide ice sheet - Wikipedia

    en.wikipedia.org/wiki/Laurentide_ice_sheet

    This ice sheet was the primary feature of the Pleistocene epoch in North America, commonly referred to as the ice age. During the Pre-Illinoian Stage, the Laurentide Ice Sheet extended as far south as the Missouri and Ohio River valleys.

  4. Quaternary glaciation - Wikipedia

    en.wikipedia.org/wiki/Quaternary_glaciation

    The formation of 3 to 4 km (1.9 to 2.5 mi) thick ice sheets equate to a global sea level drop of about 120 m (390 ft) The Quaternary glaciation , also known as the Pleistocene glaciation , is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.

  5. Cordilleran ice sheet - Wikipedia

    en.wikipedia.org/wiki/Cordilleran_ice_sheet

    Unlike the Laurentide Ice Sheet, which may have taken as many as eleven thousand years to fully melt, [3] the Cordilleran ice sheet melted very quickly, probably in four thousand years or less. [4] This rapid melting caused floods such as the overflow of Lake Missoula and shaped the topography of the fertile Inland Empire of Eastern Washington. [5]

  6. Late Cenozoic Ice Age - Wikipedia

    en.wikipedia.org/wiki/Late_Cenozoic_Ice_Age

    Although different ice sheets reached maximum extent at somewhat different times, this was the time when ice sheets overall were at maximum extent. According to Blue Marble 3000 (a video by the Zurich University of Applied Sciences), the average global temperature around 19,000 BCE (about 21,000 years ago) was 9.0 °C (48.2 °F). [25]

  7. Weichselian glaciation - Wikipedia

    en.wikipedia.org/wiki/Weichselian_glaciation

    The Fennoscandian Ice Sheet of the Weichselian glaciation most likely grew out of a mountain glaciation of small ice fields and ice caps in the Scandinavian Mountains.The initial glaciation of the Scandinavian Mountains would have been enabled by moisture coming from the Atlantic Ocean and the mountains high altitude.

  8. Last Glacial Period - Wikipedia

    en.wikipedia.org/wiki/Last_Glacial_Period

    An artist's impression of the last glacial period at glacial maximum [4]. The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.

  9. Deglaciation - Wikipedia

    en.wikipedia.org/wiki/Deglaciation

    Throughout the Pleistocene Epoch, the Laurentide Ice Sheet spread over large areas of northern North America, with over 5,000,000 square miles of coverage. The Laurentide ice sheet was 10,000 feet deep in some areas, and reached as far south as 37°N.
