permafrost is a layer of frost, that never fully melts.
A constant sheet of snow and ice as it were, found in the tundra.

It used to be a permanently frozen area, as implied by the name, however sections that used to be considered permafrost have now melted, so the term needs to be redefined I think.

Water laden earth that is frozen and never warms up enough to thaw. Permafrost sounds better that permafroze
