- In the last decade deposition on lateral moraine embankments of glacier de Tsidjiore Nouve has been re-activated on a large scale. An attempt has been made to reconstrucl, from the dimensions of the embankments, average rates of debris accumulation on the moraincs during the Neoglacial period. These are compared with rates of deposition over the period 197 7-82, calculated from detailed changes in moraine profiles (surveyed by ground- and air-based photogrammetry) and measured rates of ice-margin ablation. At present total output of sediment, by marginal deposition and transport by melt-water streams, from glacier de Tsidjiore Nouve is in the order of 6 400- 9 500 m'/a; this suggests the possibility of a high average erosion rate within the glacier catchment of 1.55-2.29 mm/a.
