Wisconsinan
Discussion of the Glacial Limits. The limit of the most recent glaciation or the 'Terminal Moraine' was traced across the entire state of Pennsylvania by Lewis (1884) and assigned a Late Wisconsinan age by Chamberlin (1883). In north-western Pennsylvania, that limit was remapped and refined by Shepps et al. (1959).Geologists working for the North Dakota Geological Survey have identified glacial deposits in the southwestern part of the state that are well beyond the Late Wisconsinan ice marginal limit. These consist of patches of much-older glacial sediment or, in places, areas of sporadic erratic boulders.

The most-recent glacier, the Late Wisconsinan glacier, covered all of the eastern and northern parts of the state between about 25,000 and 20,000 years ago. The edge of the Late Wisconsinan glacial deposits is well defined and coincides with the edge of the glacier. The ice at the edge of the glacier was thin, the ice presumably thinning to ...during the early Wisconsinan glaciation (MIS 4) around 75 0 00 years ago created unfavorable envi-ronmental conditions, eliminated browse, and le d to their local extirpation in eastern Berin gia.2nd Place: Wisco.

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.
