5.2.1 Soils of Northern and Eastern Wisconsin. Forested, red, sandy, and loamy soils (soil region E). This region encompasses deposits with a red color and sandy and loamy textures that are of Late Wisconsinan age (Fig. 2.6).Hole (1976) delineated 13 soil associations in this region (E) that were Alfisols , Entisols , Inceptisols, Mollisols , …son (1949) proposed that the drumlin till in Boston was of early Wisconsinan age and this age assignment was retained in regional summaries (Muller, 1965; Scha­ fer and Hartshorn, 1965; Stone and Borns, 1986). Further consideration of radio­ carbon age constraints on the late Wisconsin glaciation (Stone and Borns, 1986),limits to Late Wisconsinan ice thickness of between 250 and 920 m in northeastern North Dakota. As a check on their ice thickness model, they calculated the basal stresses indicated by their ice thick­ ness limits and compared chem to basal shear stresses calculated by other researchers for the Des Moines Lobe.The late Wisconsinan (25-10 ka bp [ka = thousands of radiocarbon years]) North American ice sheet complex consisted of three major ice sheets: the Laurentide Ice Sheet, which was centered on the Canadian Shield but also expanded across the Interior Plains to the west and south; the Cordilleran Ice Sheet, which inundated the western mountain ...Geochemical data and geophysical measurements from a 554‐m ice‐core from Taylor Dome, East Antarctica, provide the basis for climate reconstruction in the western Ross Embayment through the entire Wisconsinan and Holocene.Wisconsinan Glaciation. The last ice advance into Ohio, the Wisconsin Glaciation, began around 35,000 years ago and ended roughly 12,000 years ago, when ice retreated out of the Lake Erie Basin. Ice reached its maximum extent in Ohio around 26,000-24,000 years ago during a time known as the Last Glacial Maximum (LGM). During this time ...Monroe, Wisconsin Military Bases. Fort McCoy is one of the primary training bases in the United States of America. It is located near between Sparta and Tomah, Wisconsin in Monroe County. It spreads over 240 square kilometers and has always been one of the main training facilities for the US Army. Its objectives haven't changed too much over ...Numerous clastic intrusive sheets, a few decimetres to more than 16 m long, 1-120 cm thick, and extending one to more than 25 m laterally, occur along a 350 m long section of the late Wisconsinan Catfish Creek Drift in the Lake Erie bluffs at Bradtville, southwestern Ontario. Most of them are downglacier-dipping dikes, the largest one terminating in the underlying middle Wisconsinan Tyrconnell ...Wisconsinan in age and are conventionally thought to relate to the Illinoian glaciation, but they may in­ stead relate to other pre-Wisconsinan stages. At present there is no convincing rationale to dis­ criminate among the pre-Wisconsinan events in southern Indiana. ICE-MARGINAL DRAINAGE IN SOUTHWESTERN INDIANAIn central British Columbia, ice flow during the late Wisconsinan Fraser glaciation (ca. 25-10 ka) occurred in three phases. 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.Remapping of Wisconsinan limit. the Late Wisconsinan limit by Crowl & Sevon (1980) and the radiocarbon dates mentioned above have convinced all that the Late Wisconsinan limit is the same age in both north-eastern and north-western Pennsylvania and that age is about 20 ka.moraines and outwash. Ridge (1983) defined the late Wisconsinan history of part of Kittatinny Valley extending from the terminal moraine to the Sussex-Warren County boundary. He did this by employing a morptK)stratigraphic aprxoach by Koteff (1974). and Koteff and Pessl (1981) to map the distribution Of He that deposits in KittatinnyThe Wisconsinan Terminus transects the basin into two regions (Fig. 1). Northern watersheds above the glaciation boundary (glaciated watersheds) are characterized by low gradient streams draining mostly flat or gently rolling terrain (Daniel et al. 2010). Southern watersheds that were unaffected by the Wisconsinan glaciation …During the last glaciation, shifts in climate altered the world’s vegetation patterns from what they had been prior to the formation of the ice sheets. However, the types of vegetation present during the glaciation are similar to those found today. Many such trees, mosses, flowering plants, insects, birds, shelled mollusks, and mammals are ...Wisconsinan lacustrine deposits (stratified silt, clay, peat, and muck) occur along some rivers and tributaries and between moraines in the northeastern part of the Section. Bedrock beneath the drift is composed of lower Mississippian limestones, shales, and sandstones, well exposed on the uplands between the lower Illinois River and the ...Ground-moraine dominated areas have a shallow DTB, the Ice-deposited Wisconsinan-age ridge moraines generally have a medium DTB, and limited areas of …

Ice streams in the tributary channels draining the Laurentide and Innuitian ice sheets flowed into Barrow Strait and Lancaster Sound and thence eastward toward Baffin Bay. The resulting major Late Wisconsinan ice stream in Lancaster Sound was interpreted by Li et al. (2011) to have flowed eastward to a grounding line at ∼1300 m water depthDrumlin fields in North America are no older than late-Wisconsinan. and all preserved drumlin fields of significant size appear to have formed during this time period in the late Pleistocene. If drumlins formed during earlier glacial time, they probably were eroded or masked by subsequent glaciations. Only three fields, consisting of a few very ...The Late Wisconsinan deglaciation period was a time of rapid climate adjustment that resulted in the widespread transition from proglacial/paraglacial conditions to non-glacial settings favourable for plant and animal colonization. Establishing the timing of this transitional period in northeastern British Columbia provides constraints on the ...For Barnes Ice Cap, the late Wisconsinan and LGM δ 18 O values are much lower (−34.3 ± 2.4‰ and −41.7‰, respectively), suggesting surface ice elevations for most of the last glacial ...He simplified Rutter's (1977) stratigraphy and proposed a pre-middle Wisconsinan Cordilleran event and a short late Wisconsinan event (lasting ∼5000 yr) of limited extent, supported by sub-till radiocarbon ages of 15,180 ± 100 14 C yr BP (18,690–18,160 cal yr BP) (calibration using OxCal 4.2 and the IntCal 13 data set; Bronk Ramsey, 2009 ...

Wisconsinan history of northern Maine are proposed to explain the observed relationship between the Van Buren and Mars Hill Drifts: a) Separate Ice_Cap Model: A separate ice cap developed in central Maine during mid Wisconsinan time which eventually expanded and interacted with the advancing Laurentide Ice Sheet from north present, but age control for all except Late Wisconsinan events is limit-ed to palaeosols and palaeomagnetic data (Whittecar, 1979; Baker et al., 1983; Miller, 2000). Radiocarbon ages are abundant for the Late Wisconsinan deglaciation after 13,000 14 C yr B.P., but they are much less common for earlier Wisconsinan events.…
