Wisconsinan.

Wisconsinan, Illinoian and pre-Illinoian, based mainly on semi-quantitative relative-weathering criteria and com-parison with the mid-continent. Abouthalf of the local sequences included a two-fold subdivision of the Wisconsinan glaciation (Early and Late) and many authors recognised multiple advances early during the Holocene.

Geomorphic mapping, landform and sediment analysis, and cosmogenic 10 Be and 36 Cl ages from erratics, moraine boulders, and glacially polished bedrock help define the timing of the Wisconsinan glaciations in the Chugach Mountains of south-central Alaska. The maximum extent of glaciation in the Chugach Mountains during the last glacial period (marine isotope stages [MIS] 5d through 2) occurred ...Wisconsinan drift that dates from 21,750 BP mantles the older glacial sediments. This drift was deposited from a lobate ice front dominated by the Hudson Lobe on the west, the Connecticut Lobe in central Long Island and the Connecticut-Rhode Island Lobe in the east. The Hudson and Connecticut lobes are separated by an ...wisconsinan (14,000 to 24,000 years old) illinoian (130,000 to 300,000 years old) pre-illinoian (older than 300,000 years) williams fulton lucas ottawa wood henry defiance hardin hancock auglaize allen putnam mercer van wert paulding holmes erie sandusky seneca huron lorain medina crawford richland ashland wayne morrow wyandot marion carroll ... The concept of a Last Glacial Maximum (LGM) dominates the Quaternary literature and ideas associated with the last glacial cycle (Weichselian, Wisconsinan, Valdaian Stage, Marine Isotope Stages [MIS] ca. 5d-2). However, neither its meaning nor its stratigraphic definition is well defined.

Late Wisconsinan deposits are widespread, consisting largely of sand and silt (defined herein as silty sand), and probably accumulated in a very low energy fluvial environment. Radiocarbon ages from the lower part of the silty sand range from about 20,000 yr B.P. to around 9,000 yr B.P. At all localities, the silty sand contains one or two ...Composition of arvicolid and soricid faunal components is a better latitudinal indicator than is diversity of those components. Unlike Wisconsinan mammalian faunas of the southern and eastern United States, those of the Central and Northern plains consist almost entirely of steppe and boreal taxa. Boreal taxa predominate in the northern faunas.

Abouthalf of the local sequences included a two-fold subdivision of the Wisconsinan glaciation (Early and Late) and many authors recognised multiple advances early during the Holocene.The principal effect of the Wisconsinan glaci-ation was to influence the distribution of the native North American earthworm fauna, with total extirpation of earthworms from soils directly affected by ice sheets and permafrost. Since the recession of the glacial ice sheets, climatic factors have been the primary drivers in the distribution

The till occurs near the late Wisconsinan drift border and below fossiliferous marine beds of oxygen-isotope stage 5 (Sangamonian) age.

During late Wisconsinan retreat, moraine deposits dammed the valley at the Narrows to form Lake Albany.

The ice expansion phase occurred during an extended period when glaciers flowed westward to the Pacific Ocean and east-southeastward onto the Nechako Plateau from ice centers in the Skeena, Hazelton, Coast, and Omineca Mountains.The Late Wisconsinan and Holocene record of the Atlantic walrus is known from numerous collections of bones and tusks from Arctic Canada and south to North Carolina, as well as from many archaeological sites in the Arctic and Subarctic.of the late Wisconsinan .-S.-F Lake Michigan lobe.

The soil C horizon shows this decrease to some extent but not as clearly as the soil A horizon. The northern limit of kaolinite–rich soils corresponds to the southern limit of the youngest (Wisconsinan) Pleistocene glaciation (Soller and others, 2012). North of that boundary, soils are relatively young and formed from glacial deposits ...

2). During the most recent glacial advance (Wisconsinan Stage), ice extended nearly as far south as the Ohio River ~21,000 years ago. Th ereaft er, the ice margin receded in pulses with several ridges of glacial debris (moraines) being deposited under what is now the bed of Lake Erie (Lewis and others 2012). Prominent end moraines occur
