The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glacial epochs, from 2.58 million years ago to the present.. The last advance covered most of northern North America between c. 95,000 and c. 20,000 years before the present day and, among ...

Only one glaciation observed in western Alberta, Canada—the ice-age reinforcement syndrome. by Michael J. Oard. For about 60 years, from about 1910 to 1970, it was claimed that there were four global ice ages, give or take one. 1 This notion first arose with the recognition of four gravel layers in river valleys along the north slope of the Alps in Europe by Penck and Brückner in the late ...

The transition from Middle Wisconsinan to Late Wisconsinan is imprecisely dated in eastern Beringia, but floral and faunal data indicate that conditions changed from interstadial to glacial by about 29 kyr BP (Hamilton and Fulton, 1994, Anderson and Lozhkin, 2001).

Wisconsin was glaciated several times during the Quaternary and lies well north of the maximum extent of Quaternary glaciations. …Two pre-Late Wisconsinan tills in western Wisconsin are thought to represent events during the Illinoian Glaciation of the Middle Pleistocene (MIS 6 or 8). The River Falls Formation (the 'old red' till of Leverett, 1932 ) and the Bakerville Member of the Copper Falls Formation were deposited by ice from the Superior region ( Figs. 42.4 and ...Late Wisconsinan glacial extent Figure 1 .-Location of the Grand Calumet River region at the southern end of Lake Michigan, and the extent of Late Wisconsinan glaciation in th e Great Lakes region. (Hansel et al. 1985) much of the Laurentide Ice Sheet was confined to the Great Lake ba-sins, giving a lobate pattern to the ice margin (e.g., Fig. 2). Geomorphic, stratigraphic and geochronological evidence from northeast British Columbia (Canada) indicates that, during the late Wisconsinan (approximately equivalent to marine oxygen isotope stage [MIS] 2), a major lobe of western-sourced ice coalesced with the northeastern-sourced Laurentide Ice Sheet (LIS).Glacigenic sediments and sedimentary structures at Camano Island and Whidbey Island, Puget Sound, provide evidence for both ductile deformation and brittle fracture processes …

The Last Glacial Period ( LGP ), also known colloquially as the Last Ice Age or simply Ice Age, [1] occurred from the end of the Eemian to the end of the Younger Dryas, encompassing the period c. 115,000 – c. 11,700 years ago. The LGP is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation which ... Late Wisconsinan to Pre-Illinoinan glacial events in eastern Pennsylvania.

The Recent Lake and Wetland unit began forming during Port Bruce time, based on vertebrate fossils and 14 C dates as old as 12,800 yr BP, and probably spans all of ...Williams County, in northwestern North Dakota, is located near the center of the structural and sedimentary Williston basin. The preglacial sedimentary formations beneath the county are as much as 14,828 feet thick. Their beds dip generally to the south except along the flanks of the north-south striking Nesson anticline in the eastern part of the county.A late Wisconsinan marine deposit of nonglacial origin overlies the glaciomarine deposits in Cape Cod Bay. Both deposits indicate that the crust was isostatically depressed below the late Wisconsinan eustatic sea level and that deglaciation and marine submergence occurred simultaneously. Valleys cut into the marine deposits, both glacial and ...The response of continental-scale drainage systems to short-term (i.e., millennial-scale) climate change is unknown but has wide implications for understanding climate feedbacks and terrestrial-marine fluxes.The features include the following. (1) A pair of end morained formed during the retreat of the Laurentide Ice Sheet from the Gulf of Maine (Oldale, 1985a). (2) A barrier spit and lagoon complex and (3) a paleodelta, both of which formed during a late Wisconsinan to early Holocene low relative sea-level stand (Oldale and others, 1983; Oldale ...Wisconsinan glacial deposits blanket the surface throughout the northern, central, and western portions of the state. The last of the ice was gone from Ohio by about 14,000 years ago. Wisconsinan deposits are well preserved because of the relatively short interval of erosion and weathering since their deposition.Around 70,000 years ago the temperature dropped and snow and ice began to accumulate in northern Canada, forming a great sheet of ice known as the Wisconsinan glacier. Under its own weight, the glacier pushed its way south, eventually reaching northern United States around 24,000 years ago. At the Erie basin it was approximately 1 mile thick ...Throughout the Wisconsinan Episode, large lakes containing glacial meltwater formed along the margins of the ice lobes (Fig. 2). Glacial Lake Grantsburg was dammed north of the Twin Cities by the Grantsburg sublobe. Farther to the north, glacial Lakes Upham and Aitkin were formed in front of the St. Louis sublobe.

The classification of the Wisconsinan Stage by Frye and Willman combines into Woodfordian time the intervals Tazewell, Cary, and Port Huron of the Lake Michigan lobe because these three intervals, unlike the Twocreekan that follows, cannot be defined or traced satisfactorily on a stratigraphic basis.

Ecosystem Evolution. Before Human Transformation (Map) When Chicago's first human inhabitants arrived at the end of the last ice age, they encountered a landscape much different from what the Europeans observed 11,000 years later.

Wisconsinan Glaciation. The last ice advance into Ohio, the Wisconsin Glaciation, began around 35,000 years ago and ended roughly 12,000 years ago, when ice retreated out of the Lake Erie Basin. Ice reached its maximum extent in Ohio around 26,000-24,000 years ago during a time known as the Last Glacial Maximum (LGM). During this time ...The named stratigraphic units of the Wisconsinan Stage, the Peoria silt member and the Bignell silt member, are included within the Sanborn formation. However, extensive alluvial deposits of early Wisconsinan and late Wisconsinan ages and accumulations of eolian dune sands are extensive in the State but have not been assigned formal names. Three maps portray various possible ice limits.
