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.Bootherium. Bootherium (Greek: "ox" (boos), "beast" (therion) [1]) is an extinct bovid genus from the middle to late Pleistocene of North America which contains a single species, Bootherium bombifrons. [2] Vernacular names for Bootherium include Harlan's muskox, woodox, woodland muskox, [3] helmeted muskox, [4] or bonnet-headed muskox.

Trees grew on the Snake River plain during maximum glacial cool intervals about 140,000 and 20,000 years ago. When the glaciers melted, constrictions in canyons produced local dams and periodic floods, on the Snake River, Columbia River, and Big Lost River ...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. Despite thisThe Older deposits are from a pre-late Wisconsinan glaciation and occur in the Highlands south of, and in places beneath, the Terminal Moraine. The pre-late Wisconsinan deposits were first described by Salisbury (1892), who considered them to be post-Kansan and, in places, Wisconsinan, in age, in contrast to the moreData Summary - Pennsylvania Spatial Data Access ... abstract

Composition of arvicolid and soricid faunal components is a better latitudinal indicator than is diversity of those components. Unlike Wisconsinan mammalian faunas of the southern and eastern United States, those of the Central and Northern plains consist almost entirely of steppe and boreal taxa. Boreal taxa predominate in the northern faunas.Thousands of years ago, the melting mile-thick glaciers of the Wisconsin Ice Age left the North American continent a magnificent gift: five fantastic freshwater seas collectively known today as the Great Lakes — Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Ontario.

Rarely, there is a major hyperpycnal flow of gravel and sand, together with widespread mud deposition. More frequently, coarse-grained hyperpycnal flow is minor or lacking and principally mud is discharged either in a hypopycnal or a lofting hyperpycnal plume. Water discharge in each late Wisconsinan event was at least 10 4 km 3. 3.t. Highland climates are the only climate region that is created by topography and not latitude. t.

The strong northwesterly winds eroded troughs and ridges in the zone adjacent to the ice margin and swept the zone free of snow so that permafrost developed. Lakes formed where drainage was blocked ...Jul 27, 1998 · Late Wisconsinan deposits are widespread, consisting largely of sand and silt (defined herein as silty sand), and probably accumulated in a very low energy fluvial environment.

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.

New York may be presumed to have experienced several glaciations, deposits of pre-Wisconsinan glaciations are preserved only in unusual situations. Where glacial deposits are inset within protected gullies, transverse to the main flow of glacier ice, older drift may have escaped erosion during later glaciation. It also reviews that patterns of ...
