Abstract

An unusually wide variety of pingo landforms located within a relatively restricted area of thick surficial sediments and permafrost is documented. Pingo growth and decay may occur independent of climatic change as witnessed by examples of embryonic, active and collapsed/collapsing features. The presence of deep kettle lakes in the area probably creates a dynamic system of interlinked taliks which influence the groundwater supply to centres of ground ice growth. All the pingos post-date the Last Glacial Maximum ice retreat and the youngest was actively growing in AD 1981
