Abstract

Scandinavian networks of relict ice wedge polygons are revealed by aerial photographs. The most regularly shaped and equally sized polygons occur in south-western Jutland. This is a result of the long period of periglacial frost activity in the environment outside the Weichselian Ice Sheet. The relict polygon areas on the Swedish west coast and in north-eastern Norway are situated in early deglaciated regions. Using dated shoreline records, it may be concluded that these polygons had their last period of activity in the Younger Dryas cold phase. To gain experience of the dynamics of ice wedges, the high-arctic Adventdalen Valley, Svalbard, was chosen as test area. Secondary wedges observed are interpreted as indicators of climatic cooling
