How far south did the glaciers go.
the glaciers, called the Wisconsin Stage. Ice fanned out prominently from the Laurentian Highlands, east of Hudson Bay, and pushed southward to central Illinois, Indiana, and Ohio. The earlier stages had advanced as far south as the Ohio River. As the Wisconsin glacier moved forward, it enveloped the loose
Wisconsinan ice reached as far south as Nebraska and Iowa, and glacial deposits from this period provide important clues to the Pleistocene ecology and climate. The Wisconsinan Stage at the end of the Pleistocene Epoch was followed by the Holocene Epoch (11,700 years ago to the present).How far south did the glaciers go?

Sand and gravel in eskers, kames, kameterraces,andoutwash,princi-pally in valleys; silt and clay in lake deposits in formerly ice-dammed valleys; lake clays and beach sandsDec 21, 2020 at 3:57 1 If you google for "Laurentide Ice Sheet flow" and click "images" you will find maps with arrows. It looks complicated - some seem to show flow towards the continental divide in northern Alberta/BC. Note that there can be isostatic depression of the land due to the weight of ice, so "downhill" was not the same as now.
Glaciers are the reason we have igneous and metamorphic boulders in parts of Ohio. As glaciers advanced southward across Canada, they eroded igneous and metamorphic bedrock. These boulders were carried by the ice into Ohio. The boulders can be transported hundreds of miles by being trapped within glacial ice until conditions of the ice flow …Two glacial advances, or periods of growth in a glacier, formed Long Island. Today, residents of Ithaca, New York, a city in the Finger Lakes region known for its gorges and for being home to Cornell University, remember the impact that glaciers had on their landscape and, in turn, their history. Eighteen thousand years ago, the Laurentide Ice ...A glacier is a large mass of ice which is thick enough to deform and flow under its own weight. During the Pleistocene Epoch, conmmonly known as the "Ice Age", great continental-scale masses of ice spread southward into Pennsylvania from Canada. The ice never made it as far south as Pittsburgh, instead ending at Morraine State Park.around 12,000 to 10,500 years ago. The most recent advancement of glacial ice in Minnesota spanned from around 12,000 to 10,500 years ago. By this time, the ice had melted back out of Iowa and up into the lowland area of Minnesota. When these lobes melted back into the Red River Valley and the Lake … When Was The Last Ice Age In Minnesota? Read More »
