   Alternative forms: alass, alaas

   […] alasses probably exist south of the Yukon Flats. Another bus tour went to the east, and alasses and pingos were examined on the terraces.

   […] alasses. They are formed when a large quantity of ground ice thaws (up to 80% by volume) in permafrost. Alasses are characteristics of the thermal degradation stages of permafrost. Their subsequent thaw induces a lowering of the [terrain].

   […] permafrost (yedoma), the large volume loss that accompanies the melt of excess ice to produce an alas is irreversible, and secondary thermokarst lakes developed in ice-rich epigenetic permafrost on the alas floor are likely to be much smaller and shallower than the original thermokarst lake.

Formas
