The unstable bulk density profiles and viscous nature of wet soils with permafrost facilitate flow of soil by diapirism. Soil material with low bulk density due to very high ice content is commonly present near the permafrost table. Horizons with gravimetric water contents of 1 to 2 kg water per kg...
