Palsas, lithalsas and remnants of these periglacial mounds. A progress report
There is no general agreement about the meaning of the word 'palsa'. Usage and recent suggested definitions indicate that the word is chiefly used for cryogenic mounds covered by peat that were formed by an accumulation of segregation ice in the discontinuous permafrost zone. Lithalsas are...
