Extensive areas of uplifted Holocene marine sediments are covered by permafrost mounds - domes and ridges up to 7 m high, and thermokarst lakes. The domes are related to both open system pingos and palsas but the ridges are of uncertain origin and not hitherto described. They all may be the result of an extension of permafrost in the late Neoglacial following a milder mid Holocene period.
