- n. Soil creep caused by waterlogged soil slowly moving downhill on top of an impermeable layer.
Extensive periglacial phenomena, such as solifluction fields, are still active at higher elevations.
Thawing of permafrost soils can result in subsidence of the surface, thermokarst, and activation of freeze – thaw related processes such as solifluction.
The flora of the area is a low-arctic type, typical of the nutrient-poor silicaceous soil which, where humid, shows solifluction effects such as frost boils.
