The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~2.6 million years. This included the following areas: Western Montana; The Idaho Panhandle; Northern Washington state down to about Olympia and Spokane; All of British Columbia; The southwestern third or so of Yukon Territory

The Antarctic ice sheet is the largest single mass of ice on Earth.It covers an area of almost 14 million km 2 (14 Mm 2) and contains 30 million km 3 of ice. Around 90% of the Earth's ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters. The continent-wide average surface temperature trend of Antarctica is positive and significant at >0.05 °C/decade …

The Cordilleran ice sheet nucleated in the high mountains of British Columbia (Figs. 44.3 A and 44.4 A). Small mountain ice fields grew, and valley glaciers advanced when climate deteriorated early during each glaciation (Fig. 44.3 B; Kerr, 1934; Davis and Mathews, 1944; Fulton, 1991).With continued cooling and an increase in precipitation, glaciers expanded and coalesced to form a …

The Cordilleran ice sheet was a major ice sheet that periodically covered large parts of North America during glacial periods over the last ~2.6 million years. This included the following areas: The ice sheet covered up to 2.5 million square kilometres at the Last Glacial Maximum and probably more than that in some previous periods, when it may have extended into the …

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 2.588 ± 0.005 million years ago to the present.. The last advance covered most of northern North America between c. 95,000 and c. 20,000 years …

the Laurentide ice sheet to form a continuous ice sheet over 4,000km wide. Because most of the marginal environments of the Cordilleran ice sheet were not conducive to preserving an extensive depositional record, much of our understanding of this ice sheet has come from limited areas where preser-vation is good and access unencumbered, notably ...

Ne Ch'e Ddhäwa is the Northern Tutchone name for an eroded tuya approximately 7 km up the Yukon River from Fort Selkirk (UTM zone 8V 383955 E, 69600091 N) (it has been informally called Wootten's Cone) in the Fort Selkirk Volcanic Field of central Yukon, Canada. It has been described as a cinder cone or a subglacial mound. The volcano erupted subglacially between 2.0 and 2.3 …
