Rubbing boulders, fossil mammal teeth, barrier islands, and a change in volcanic behavior

ve. Johnny W. Sanders and colleagues present nearly two years of environmental measurements made in three cirque glacier bergschrunds (West Washmawapta Glacier, British Columbia, Canada and Conness Glacier, Sierra Nevada, California). Their measurements, coupled with a numerical model of ice lens growth in idealized cracks, indicate that frost weathering by ice segregation crack growth is a viable mechanism for dismantling the headwall both above and within the bergschrund. Only in the bergschrund, however, is the glacier able to entrain the loosened rock. A slight reduction in temperature -- more typical of the Pleistocene -- shifts the locus of frost weathering to within the bergschrund.


The 8.2 ka event -- Calendar-dated glacier response in the Alps

Kurt Nicolussi and Christian Schlchter, Institute of Geography, University of Innsbruck, Innrain 52, A-6020 Innsbruck, Austria. Posted online 18 July 2012; doi: 10.1130/G32406.1.

The "8.2 ka event" (8.2 thousand years ago) has been identified as a major Holocene climatic cooling episode in the North Atlantic realm. This event was recognized as the most extreme climatic anomaly in the Greenland ice core records during the Holocene. However, clear evidence in terms of a major climate archive, mountain glaciers, has been missing so far for the European Alps. In the light of the tree-ring analysis of tree remains found in front of the glacier snout of the Mont Min Glacier during the past few years, the first calendar-dated evidence for a glacier advance within the 8.2 ka cooling event worldwide can now be presented. Several tree fragments date this advance from 8183 to 8168 years before A.D. 2000. The Mont Min Glacier reached the current ice extent at that time. This 8.2 thousand-year-old advance terminates a long-lasting retreat period of the Mont Min Glacier that goes back at least to about 9100 years before A.D. 2000, and during that time, the Mont Min Glacier was continuously s
