Explanation:
Solifluction, flowage of water-saturated soil down a steep slope. Because permafrost is impermeable to water, soil overlying it may become oversaturated and slide downslope under the pull of gravity. Soil that has been opened and weakened by frost action is most susceptible.
an isolated, tongue-shaped solifluction feature, up to 25 meters (27 yards) wide and 150 meters (164 yards) or more long; formed by more rapid solifluction on certain sections of a slope showing variations in gradient. frozen ground or permafrost
.
Solifluction happens during the summer thaw when the water in the soil is trapped there by frozen permafrost beneath it. This waterlogged sludge moves downslope by gravity, helped along by freeze-and-thaw cycles that push the top of the soil outward from the slope (the mechanism of frost heave).
