[¦jel·ə¦flək·shən]

The slow, continuous downslope movement of rock debris and water-saturated soil that occurs above frozen ground, as in most polar regions and in many high mountain ranges. Also known as congelifluction; gelisolifluction.

A variety of slope failure types has occurred in Newfoundland and Labrador, including sackung; rockfalls; debris torrents and floods; channelized debris flows and debris avalanches; rotational slumps; and gelifluction creep.
The original morphology and sediment composition of these landforms are in places significantly modified by processes such as creep, gelifluction, and sorting.
If the cryogenic structure is stable, the water drains between the aggregates and the movements soon slows down; this is called gelifluction. If, to the contrary, the aggregates collapse and the water does not drain easily, the supersaturation causes liquefaction to occur, and mudslides (surface flows) occur.
