Five sedimentary units and three erosional unconformities identified in high-resolution seismic-reflection profiles reveal the stratigraphic framework and Quaternary history of the inner continental shelf south of Narragansett Bay, Rhode Island. Late Tertiary to early Pleistocene rivers eroded the pre-Mesozoic bedrock and the Upper Cretaceous to lower …This document is a bulletin published by the US Geological Survey in 1987, titled "The Wisconsin Glaciation in the Northeastern United States". It provides a comprehensive review of the geology, stratigraphy, chronology, and paleoenvironment of the last glacial episode in the region, covering 14 states and the District of Columbia.

Although some workers have argued that the glacial units mentioned above are all late Wisconsinan, stratigraphic, paleoecologic, and chronologic data (14 C, Th/U, and amino acid analyses), from several localities, indicate that the glacial sediments are of likely Sangamonian (broad sense) to early Wisconsinan age and that the nonglacial beds ...New data presented here show that the southern part of the Magdalen archipelago was glaciated during the Late Wisconsinan. We relate this ice flow to the Escuminac ice cap, whose centre of dispersion was located in the Gulf of St. Lawrence, northwest of the islands. At Anse au Plâtre, the top of the Drift des Demoiselles is a …Wisconsinan)-- Strati˚ed, thinly bedded, moderately to poorly sorted sand, silt, and minor gravel in thin sheets laid down on the ˜oors of small upland tributaries and the lower parts of adjacent slopes.

Publication type: Article: Publication Subtype: Journal Article: Title: Late-glacial environmental changes south of the Wisconsinan terminal moraine in the Eastern United StatesThe Wisconsinan Age (Altonian Subage) began as Roxana Silt (loess) was deposited under periglacial conditions. The vegetation was characterized by coniferous trees that grew in weakly developed, often organic-rich, cryoturbated soils. Periglacial conditions persisted during the Altonian and Farmdalian Subages, from before 50 ka to about 25 ka ...

By 10,000 B.P. the Wisconsinan ice sheet had retreated to southern Canada, and the pattern of natural vegetation throughout the Midwest was becoming similar to that of today. With the glaciers receding to the north, a re-advance of the flora occurred. This plant invasion was probably relatively rapid. Probably scattered areas of tundra followed on that region during the onset of glacial conditions of the early Wisconsinan (90,000 years ago) and late Wisconsinan (25,000 years ago). Seeds, fruits, and leaves from at least 60 kinds of plants including grasses, steppe and tundra forbs, dwarf shrubs, sage and, rarely, spruce trees have been recovered from the middens.PEOPLE (Pre-College Enrichment Opportunity Program for Learning Excellence) challenges motivated students by providing personal discovery, academic improvement, and career exploration.

The history of Late Wisconsinan glaciation in southwestern Manitoba has been established by identifying and correlating ice-laid lithostratigraphic units in the subsurface.

The first, forming a narrow belt just outside the terminal moraine, was interpreted to be glacial drift of Wisconsinan age mixed withGeochemical data and geophysical measurements from a 554‐m ice‐core from Taylor Dome, East Antarctica, provide the basis for climate reconstruction in the western Ross Embayment through the entire Wisconsinan and Holocene. In comparison with ice cores from central East and West Antarctica, Taylor Dome shows greater variance of temperature, snow accumulation, and aerosol concentrations ...Note the asymmetry of late Wisconsinan glaciers on the southern Alaska margin, with glaciers covering almost the entire landscape in contrast to the north side ...B. The most recent glaciation of Earth is called the Wisconsinan glaciation. 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. It ended by about 11,700 years ago, at the start of the Holocene Epoch.The Prairie Pothole Region that covers western Minnesota and north-central Iowa (extending into the eastern parts of the Dakotas, north-central to northeastern Montana, and north into Canada) is a region that was reached by the Laurentide ice sheet during the last glacial maximum (Wisconsinan glaciation, 85,000–11,000 years ago).Wisconsin, constituent state of the United States of America.

Older deposits may still exist under the late Wisconsinan deposits where glacial scour was minimal, such as in valleys transverse to ice flow. The total duration of Late Wisconsinan ice cover is on the order of 8,000 to 10,000 calendar years

Over the past decades, observations of buried glacier ice exposed in coastal bluffs and headwalls of ret-rogressive thaw slumps of the Arctic have indicated that considerable amounts of late Pleistocene glacier ice survived the deglaciation and are still preserved in permafrost.

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 ...

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.However, extensive alluvial deposits of early Wisconsinan and late Wisconsinan ages and accumulations of eolian dune sands are extensive in the State but have ...The Wisconsin Experience.

MNRR comprises the congressionally designated reaches (2) of the Missouri River: the 59-mile reach below Gavins Point (GP) Dam, and the 39-mile reach above Lewis and Clark Lake (the …The formation and location of the Great Lakes is a direct result of ancient glaciation and geology, yet the precise age of the lakes is not known. Scientists estimate that they are anywhere between 7,000 to 32,000 years old, with the lakes changing in shape and size throughout the millennia. But all agree the process began millions of years ...A major pre-Wisconsinan glacial event is the only possible source of the lower till on Nantucket Island, Massachusetts. The till occurs near the late Wisconsinan drift border and below fossiliferous marine beds of oxygen-isotope stage 5 (Sangamonian) age. It is considered to be Illinoian in age, but the evidence is tenuous.
