Abstract
In the central Southern Alps of New Zealand, ice-surface lowering has exposed extensive sections of lateral moraines, allowing investigation of moraine stratigraphy and genesis. The presence of multiple superposed palaeosurfaces within moraine sequences allows recognition of any disturbances, displacements or contamination of till layers and interbedded organic material. Radiocarbon dating of buried wood and soils allows comparison between the Holocene glacial history of the Eastern Ranges and that of the Westland region. The periodicity of glacier response has been similar to both areas, although the precise timing of events has differed due to local climatic and environmental factors. In general, glaciers in New Zealand expanded about 5000, 4500-4200, 3700, 3500-3000, 2700-2200, 1800-1700, 1500, 1100, 900, 700-600 and 400-100 BP.
