Yedoma exposures in northwestern Siberia, on the eastern coast of the Yamal Peninsula at the Seyakha River mouth have been studied in detail. Yedoma strata with thick ice wedges (over 20 m high) were formed in northwestern Siberia during the Late Pleistocene cryochron (dated to 30-11.7 cal ka BP). D...
