Permanent lake ice
Permanent or almost permanent ice formations of lakes, constituting continuous ice sheets that may cover the entire surface for all of the year or recede to part of the lake during summer and be accompanied or replaced by floating ice blocks, rafts and hummocks. They may, locally, seasonally or permanently, extend to the whole depth of the lake. They are characteristic of high latitude and high altitude lakes.
