Wisconsinan
The Wisconsinan ice sheet approached the sites from the the north to within about 60 km distance only. One of the profiles (Pittsburg Basin) probably reaches back to the late Illinoian (zone 1), which was characterized by forests with much Picea. Zone 2, most likely of Sangamonian age, represents a period of species-rich deciduous forests ...B. The most recent glaciation of Earth is called the Wisconsinan glaciation. It reached its maximum development about 18,000 years ago, when a "Laurentide Ice Sheet" covered central and eastern Canada, the Great Lakes Region, and the northeastern United States. It ended by about 11,700 years ago, at the start of the Holocene Epoch. Refer to FIGURE 13.13, a portion of the Whitewater ...Glacial, periglacial, alluvial, and aeolian sediments from pre-Illinoian, Illinoian, and Wisconsinan Glaciations are present, but age control for all except Late Wisconsinan events is limited to palaeosols and palaeomagnetic data. The chapter reviews that glacial sediment covers approximately three fourths of the 145,000-km2 land surface in ...

This knowledge will constrain conceptual and numerical models of Late Wisconsinan ice cover in Arctic Canada (i.e. Tarasov et al., 2012) and will lend greater insight into the myriad variables that occasioned deglaciation.

In southern New England, the late Wisconsinan till and the tills that locally underlie it are informally referred to as upper and lower tills, respectively. For the most part, the ages of the lower tills are not firmly established, and regional ...
The youngest of the several episodes to have impacted the Great Lakes basin is termed the Wisconsinan episode which lasted from about 55,000 to 10,000 years ago. The maximum advance occurred about 20,000 years ago (Figure 5). During this advance, unconsolidated glacial debris left after retreat of previous glacial episodes wasScenario - what do you do ???

The low-relief landscapes offer very few exposures of their internal composition. Erosion on a large scale is the key to the geological origins of the Iowan Surface. Earlier in its landscape evolution, before the Wisconsinan glacial events, the region was actually part of the Southern Iowa Drift Plain. It was last visited by glaciers in Pre ...Adapted from Fleming and others (1993) and Brown and Laudick (2003). The glacial sediments between the modern land surface of Marion County and the buried pre-Wisconsin surface were deposited during at least three ice advances (fluctuations of the Huron-Erie Lobe) that occurred after about 22,000 years before present (yr B.P.), and are thus of late Wisconsin age.In the Connecticut Valley of southern New Hampshire and Vermont the advance of Late Wisconsinan ice buried advance outwash and lake beds were deposited in tributaries impounded by advancing ice.
