Description :
This paper investigates the occurrence of subsurface ice in a periglacial environment and addresses the potential for its preservation in a high arctic environment such as Bylot Island. The processes associated with the burial of glacial, icing and permanent snow bank ice are discussed, and specific examples are given from 3 different environments (ice-cored moraines, ice-cored deltas and icings). The impacts of thermokarst and retrogressive thaw flow erosion on the preservation of ground ice are also addressed.
