Wisconsin Glacial Limit (1:500,000) - Shows the Wisconsin glacial limit in Indiana as delineated by mapped glacial deposits. The mapped units include glacial till that is interpreted to have been deposited during the Wisconsin Glaciation. The last major expansion of the North American Laurentide Ice Sheet occured in the Wisconsin glacial episode.sult of the most recent or Wisconsinan‑age glaciers. The material left by the ice sheets consists of mixtures of clay, sand, gravel, and boulders in various types of deposits of different modes of ori-gin. Rock debris carried along by the glacier was deposited in two principal fashions, either directly by the ice or by meltwater from the glacier. Throughout the Wisconsinan Episode, large lakes containing glacial meltwater formed along the margins of the ice lobes (Fig. 2). Glacial Lake Grantsburg was dammed north of the Twin Cities by the Grantsburg sublobe. Farther to the north, glacial Lakes Upham and Aitkin were formed in front of the St. Louis sublobe.

The greatest confirmation during these two decades came from sea-floor coring; sea-surface temperatures and oxygen isotopes showed one cool long …The named stratigraphic units of the Wisconsinan Stage, the Peoria silt member and the Bignell silt member, are included within the Sanborn formation. However, extensive alluvial deposits of early Wisconsinan and late Wisconsinan ages and accumulations of eolian dune sands are extensive in the State but have not been assigned formal names.

Bootherium. Bootherium (Greek: "ox" (boos), "beast" (therion) [1]) is an extinct bovid genus from the middle to late Pleistocene of North America which contains a single species, Bootherium bombifrons. [2] Vernacular names for Bootherium include Harlan's muskox, woodox, woodland muskox, [3] helmeted muskox, [4] or bonnet-headed muskox.The response of continental-scale drainage systems to short-term (i.e., millennial-scale) climate change is unknown but has wide implications for understanding climate feedbacks and terrestrial-marine fluxes.

These consist of patches of much-older glacial sediment or, in places, areas of sporadic erratic boulders.The St. Louis Sublobe protruded from the Des Moines Lobe in northwestern Minnesota at a later date (about 12,000 yrs ago). Its meltwater flowed down the St. Louis River toward Lake Superior, but it was diverted southward into the St. Croix drainage by the still-existing Superior Lobe.

The Wisconsinan Stage has traditionally been divided into several substages representing various episodes of glacial advance and retreat (Frye and Leonard, 1952; Wilman and Frye, 1970), but recent data indicate that the names and age limits of these substages should be abandoned here in Kansas (Johnson, 1993).Hickin, A.

After retreat of Mogadore ice into the Erie Basin, ice readvanced ...Therefore, these dates suggest Langlade Lobe ice began retreating before this time. Surface exposure dates in Wisconsin imply that the Laurentide Ice Sheet began retreating from the terminal moraines at ~22,000 and/or before 18,500 years ago. This shows that ice started to retreat from the region in advance of the global rise in greenhouse ...Wisconsinan-age till; underlain by resistant Berea Sandstone Ordovician- and Silurian-age dolomites, limestones, and calcareous shales; thin pre-Wisconsinan drift on ridges in west; silt-loam colluvium Thin to thick Wisconsinan-age clay to loam till over Mississippian-and Pennsylvanian-age shales, sandstones, conglomerates and coals
