Subsurface Geophysical Investigations of Oneida Lake Ny: Insights Into Ice Sheet Processes and Deglaciation At Termination I
… encourage ice stream development. In addition, proglacial lakes also form in topographic lows, and enhance calving processes and can accelerate deglaciation or serve as corridors of easy ice sheet readvance. The deepest section of a basin likely contains the most complete and highest resolution …

Refining the span and rates of deposition of the Glenwood phase of Lake Chicago
The Glenwood phase of proglacial Lake Chicago is its oldest phase, but is the least studied. By developing the and ideas previously published maps by Bretz in the 1930s and studies by Hansel, Mickelson, Thompson and others I will be redefining the span and role of the Glenwood Phase of proglacial …

Ice dynamics and glacial history from remote sensing of the Seno Skyring-Seno Otway-Strait of Magellan region, southernmost Patagonia
… was caused by calving into one of two ice-dammed proglacial lakes. The lakes were located within the former Seno Skyring and Seno Otway ice lobes, which are well-defined by arcuate sequences of moraine ridges. The westernmost of the lakes, proglacial Lake Skyring, is delimited by a series of …

Holocene sea-level changes in the Falkland Islands: new insights into accelerated sea-level rise in the 20th Century
… attributed to the sudden drainage of Laurentide proglacial lake Agassiz-Ojibway associated with the 8.2 ka BP climatic downturn. A maximum estimate of 0.89 ± 0.22 m for this jump in the Falklands is considerably less than estimates from Northern Hemisphere records. This difference could indicate …

Evidence for Glacial Outburst Floods along the Lower Flathead River: Results from Geologic Mapping, Geomorphologic Analysis and a Gravity Survey near Polson, Montana
… and associated outwash environments, Glacial Lake Missoula (GLM), and proglacial Lake Flathead. In this study, I mapped approximately 63 square km in and around the former terminal position of the Flathead Lobe, in order to better understand the history of deglaciation in the region and better …

Glacial stratigraphy of northwestern Cass County, North Dakota
… glaciolacustrine topography, 3) proglacia1 lake sediment, 4) wave-eroded glacial and lake sediments and 5) recent river sediment. Landforms within each of these areas include eskers, abandoned or overfit river channels, transverse ridges, ice thrust masses, kettles and beach deposits.</p> …

Description and Genesis of selected Glacial Deposits, Walsh County, North Dakota
… and their relationship to the history of glacial Lake Agassiz. The deposits included till and lake sediments exposed in cuts along the Park River, while the features included two end moraines and an esker. </p><p>The field study consisted of mapping the deposits, studying their morphology and …

Cenozoic Sedimentary Evolution of the Helmville Basin, West-Central Montana
… the upper Blackfoot River drainage, impounding a proglacial lake in the study area (glacial Lake Blackfoot). A Gilbert-style delta prograded into this glacial lake from Yourname Creek drainage, located on the western edge of the study area. I infer that the Helmville basin formed as a result of …

Lake and fjord sediments as Late Glacial to Holocene environmental and climate archives of the southernmost Andes at 53°S, Chile
… a sediment core from the eastern section of the proglacial lake Seno Skyring by an ice rafted debris layer (IRD), which was formed at around 18,700 to 17,800 cal. years B.P. This indicates a rapid response of the Seno Skyring glaciers to warming of the southeast Pacific soon after the LGM. …
