Description :
The well-developed pediments, which are now densely covered by tundra vegetation, are explained as remnants of colder climatic periods from the Pleistocene. Decisive for this opinion is the connection of pediment debris with former ice wedges. Patterned ground, even on steeper slopes, is indicating the predominance of geomorphic stability. Based on numerous 14C dates, the AA. conclude that the number of cryoturbations has increased during the last 5000 years.
