Past Levels And Present State Of Northern Victoria Land Glaciers, Paul Andrew Mayewski

Earth Science Faculty Scholarship

Before 1973, movement of the Ross Ice Shelf had been measured near the Transantarctic Mountains (Swithinbank, 1963), near Ross Island (Stuart and Heine, 1961) and near the ice front and to the south of Roosevelt Island (Dorrer et at., 1969). Robin (1975), assuming steady state, extrapolated these data across the ice shelf by applying volume conservation principles to measured ice thickness profiles of the ice shelf.

Weathering Stages Of A Tholeiitic Basalt (Dolerite), Queen Maud Mountains, Paul Andrew Mayewski

Earth Science Faculty Scholarship

The sparsity of datable material and key horizons throughout most of the Transantarctic Mountains requires that much of the mapping and correlation of glacial deposits, especially moraines, be based primarily on qualitative techniques. One qualitative method is to characterize the degree of weathering of clasts covering these deposits (Behling, 1971; Calkin, 1971; Nichols, 1971; and Mayewski, 1975). Lacking, however, is a detailed understanding of the role and method of weathering. To help solve this problem, soil studies have been made by Claridge and Campbell (1968) in the Shackleton Glacier region and Everett and Behling (1968), Linkletter (1972), Behling (1971), and …

Glacial Geologic Investigation Of Upper Rennick Glacier Region, Northern Victoria Land, Paul Andrew Mayewski

Earth Science Faculty Scholarship

The 1974-1975 field season was spent investigating the upper Rennick Glacier area (figure) for (1) the relationship between the glacial history of the study area and the glacial histories already defined for more southerly sectors of the Transantarctic Mountains, (2) the history and dimensions of former fluctuations of the east antarctic ice sheet, Rennick Glacier, and its tributaries, as recorded in glacial deposits, and (3) the significance of this area in paleoclimatic reconstructions of Antarctica and the world.

Glacial Lake Evidence In Western Minnesota As Interpreted From The Soil Survey, Raymond T. Diedrick, Richard H. Rust

Journal of the Minnesota Academy of Science

Soil surveys in several counties in western Minnesota have revealed a soils pattern which provides geomorphic evidence for a previously unrecognized glacial lake. This glacial lake, here called Glacial Lake Benson, is about 60 miles long, 40 miles wide and of almost one million acres in area. Soils along its northern boundary are generally developed in coarse outwash. The central and southern portions of the lake basin have well-sorted silty soils, similar to those in Glacial Lake Agassiz. The elevation of the outer edge of the Benson basin is about 1,050 feet. Topographic maps were used to prepare transects which …

Epeirogenic And Climatic Controls Of Early Pleistocene Fluvial Sediment Dispersal In Nebraska, K. O. Stanley, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

The change from Pliocene to Pleistocene fluvial sedimentation in Nebraska is denoted by gravel with relative enrichment of mechanically weak rock species and a two-fold increase in largest clast size. These changes in fluvial sediments suggest modification in degradational energy affecting detritus apparently related to deterioration of climate in the early Pleistocene. Cooler Pleistocene climates with increased moisture resulted in greater discharge and carrying capacity for streams headed in the Rocky Mountains and flowing across Nebraska. These streams carried granitic detritus eastward toward the continental glacier margin in easternmost Nebraska. There, streams flowing off ice sheets carrying sedimentary and metamorphic …

Glacial Geology Near Mcmurdo Sound And Comparison With The Central Transantarctic Mountains, Paul Andrew Mayewski

Earth Science Faculty Scholarship

(From summary, pp. 105-106) In the central Transantarctic Mountains, the Sirius Formation consists of both a lower massive till and an upper assemblage of interlayered till and stratified lenses. Deposits of the Sirius Formation found in the McMurdo region contain only the lower massive till. The lower massive till of the Sirius Formation is thought to be a basal till because of extremely strong fabric, high concentration of faceted and striated pebbles, and heterogeneous particle sizes (clay to boulders). Fabrics observed in the basal till indicate that the ice that deposited the Sirius Formation, although displaying a much higher surface …

Department of Defense Military Intelligence

The summary on Page 5 is paraphrased as follows. This digital document is a generalized description of the Arctic Slope region -- an area covering approximately 70,000 square miles. Access to the region and the feasibility of various access routes are discussed. Location and extent of natural fuel supplies are given. Factors controlling outdoor work feasibility are summarized graphically on Page 19. A terrain analysis of each of the three major physiographic provinces of the region. Those provinces are the Arctic Coastal Plain, Arctic Foothills, and Brooks Range provinces. Geographic factors which affected cross-country movement, construction, and water supply within …

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

Glacial Geology Of Wabash County, Indiana, William J. Wayne, William D. Thornbury

Department of Earth and Atmospheric Sciences: Faculty Publications

Most of the topographic features of Wabash County are of glacial origin or are glacial deposits eroded by postglacial streams. Shales, limestones, and dolomites, all Silurian, are exposed only along some of the deeper valleys. Four major rivers and six smaller streams in Wabash County flow in glacial sluiceways. Only the Eel and Wabash sluiceways carried large quantities of melt-water. The Eel River valley train occupies an interlobate position, and the Wabash Valley bears evidence of its roles as a sluiceway and as an outlet for glacial Lake Maumee in late Cary time. Three topographic areas comprise the upland part …
