EESS Spring Seminar Series - Kurt Cuffey, Professor, Geography & Earth and Planetary Science, University of California, Berkeley, "Troughs, Cirques, and the Sierra: New Thoughts on Some Old Problems in Glacial Geomorphology", Abstract: Glacial erosion of mountain ranges produces spectacular alpine landscapes and, by linking climate with tectonics, influences a broad array of geophysical phenomena. Although the resultant landforms may be easily identified, the timing and spatial pattern of topographic adjustment to Pleistocene glaciations remain poorly known. In addition, much remains poorly understood about active processes of glacier erosion, a difficult problem to constrain observationally.
I will discuss new constraints on glacial valley formation and cirque development arising from thermochronometry, field measurements, and modeling applied to field sites in the New Zealand Fiordland and the Canadian Rockies. I will also briefly discuss preliminary work concerning the extent of glacial modification of valley systems in the Sierra Nevada of California.
