Glacier de Tsidjiore Nouve, upturned basal sediment layers
This image shows basal glacial debris layers that have been upturned to be nearly vertical as the glacier has pushed against its left lateral moraine. This process has brought basal debris to the crest of the moraine, where it is melting out and building up the crest and outer flank, an apparently common process in building lateral moraines around these extremely active, temperate glaciers. The person in the foreground is Christian Schlüchter and Geoff Boulton is talking to George Haselton (I believe) at the right side of the picture. See Roethlisberger and Schneedeli (1979) for further discussion of this specific site. Also refer to images 0125, 0128, 0140, and 0169.
