Wisconsinan drift that dates from 21,750 BP mantles the older glacial sediments. This drift was deposited from a lobate ice front dominated by the Hudson Lobe on the west, the Connecticut Lobe in central Long Island and the Connecticut-Rhode Island Lobe in the east. The Hudson and Connecticut lobes are separated by an ...

During the Wisconsinan Stage, the area of Québec-Labrador was completely covered by the Laurentide Ice Sheet (LIS), except for nunataks in the Torngat Mountains. For this reason, pre-Late Pleistocene events are only documented in scattered stratigraphical sections, and by erosional glacial marks.

Boston Run is a tributary of Kitchen Creek in Luzerne County, Pennsylvania, in the United States. It is approximately 1.2 miles (1.9 km) long and flows through Fairmount Township.

Old-growth forests are in the vicinity and wild trout naturally reproduce in the stream.Actually, the terms Wisconsinan Glaciation or Weichselian Glaciation (NW Europe) are frequently used as general terms for the last glacial cycle sensus lato. However, this …A late Wisconsinan marine deposit of nonglacial origin overlies the glaciomarine deposits in Cape Cod Bay.

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 Wisconsinan glaciation (red) peaked about 20,000 years ago. These glaciations had a major impact on Indiana geology. Glacial sediments buried much of the karst present in the older limestones north of these glacial boundaries. Today, this buried karst supplies an important groundwater source for much of northern and eastern Indiana.The Wisconsin Experience.

The last cycle of climate cooling and glacier expansion in North America is known as the Wisconsin Glaciation. About 100,000 years ago, the climate cooled again and a glacier, the Laurentide Ice Sheet, spread across the continent. Near the end of the cycle, beginning about 31,500 years ago, the glacier began its advance into Wisconsin. Wisconsinan, Wisconsinan Terrace Deposits. Character, distribution, and thickness.
