Such evidence suggests major periods of glaciation prior to the current Quaternary glaciation. One of the best documented records of pre-Quaternary glaciation, called the Karoo Ice Age, is found in the late Paleozoic rocks in South Africa, India, South America, Antarctica, and Australia. Exposures of ancient glacial deposits are numerous in ...
The Earth is currently in such an interglacial period of the Quaternary glaciation, with the Last Glacial Period of the Quaternary having ended approximately 11,700 years ago. The current interglacial is known as the Holocene epoch. [1] Based on climate proxies, paleoclimatologists study the different climate states originating from glaciation.
Quaternary glaciation began in the Alps 870,000 years ago and advanced to the Alpine Foreland 650,000 years ago. In the Alps, the four glaciations are known by the names of Bavarian rivers: Gunz, Mindel, Riss and Wurm. The Wurm glaciation is the most recent and best preserved, ending 11,700 years ago.

Detailed research by various geomorphologists and Quaternary geologists demonstrated that the two glacial tills and one ash bed stratigraphic model, on which the Yarmouthian, Kansan, Nebraskan, and Aftonian glacial - interglacial nomenclature was based, was completely wrong.
Last Glacial Period, the most recent glacial period (115,000 to 11,700 years ago) Penultimate Glacial Period, the glacial period that occurred before the Last Glacial Period; Late Cenozoic Ice Age, the geologic period of the last 33.9 million years; Little Ice Age, a period of relative cold in certain regions from roughly 1450–1480
The scoured area and other zones made up of crystalline Fennoscandian Shield rocks (northern and western Baltic Sea) have experienced overall very limited glacial erosion during the Quaternary. [7] Bathymetry of linear depressions in the Baltic seabed shows that the depression has been subject to glacial overdeepening. The date during which ...
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. [2]
