Abstract
The stratigraphic study of pingos and ice wedges on south-west Banks Island indicates a period of continuous permafrost aggradation in late Quaternary times interrupted by a temporary period of deeper seasonal thaw in the mid-Holocene. Both epigenetic and small syngenetic ice wedges are exposed in coastal bluffs south-east of Sachs Harbour. Within the Sachs and Kellett River catchments, radiocarbon dating suggests that a number of collapsed and partially eroded pingos are relict features related to a period of climatic deterioration which commenced approximately 4000 years B.P. The stratigraphic study of ground ice is thought to be a useful method of geomorphological and paleoenvironmental reconstruction, especially in areas which have experienced extended histories of cold, non-glacial conditions.
