Definition:
Talik, also called tabetisol, is a Russian term applied to permanently unfrozen
ground in regions of permafrost.


This usually applies to a layer that lies above the permafrost but below the
active layer, that is, when the permafrost table is deeper than the depth
reached by winter freezing from the surface. Talik is also found within and
beneath permafrost; when it occurs beneath the permafrost it is equivalent to
subgelisol.
