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 ...Differences in both the oxygen isotope ratio δ 18 O (8 per mil) and the deuterium excess (4.5 per mil) from the Late Glacial Stage to the Holocene are comparable with polar ice core records. These data imply that the tropical Atlantic was possibly 5° to 6°C cooler during the Late Glacial Stage, that the climate was warmest from 8400 to 5200 ...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.

Because the rate of rind development decreases with time, ratios of rind thicknesses provide limits on corresponding age ratios. In all areas studied, deposits of late Wisconsinan age are obvious; deposits of late Illinoian agWisconsinan deposits of Block Island to the Montauk Drift. However, due to the physical separation of these sections and the recognition of an outwash unit beneath the till, the two sections may be differentiated.
