Muostakh Island is a slender crescent of land in the Laptev Sea with ice-rich Yedoma permafrost.

The sun has set over Muostakh Island in the central Laptev Sea. A driftwood fire on the beach provides warmth at the end of the summer as we ready to return to civilization.

Since permafrost begins to degrade as soon as it is submerged, for example as the coastline retreats, we often work close to the coast.

Wood stoves warm the geologist tents in which we live and partly work.

A polar bear has left us a sign of its presence on the beach at Cape Mamontov Klyk in the western Laptev Sea.
