The sedimentary depression structures in the bone-rich loess horizon described by Kulick [32] as "cryoturbation and channels" also could be partially of bioturbation origin and were possibly caused by the hyenas who deposited animal prey remains in the soft soil, only in summer times, when the permafrost soil was soft in the upper parts.

Like the permafrost, podbur soils have a homogeneous profile due to cryoturbation. Despite this, gleyification does not occur, and where drainage is good the water tends to percolate downward, and this may cause podzol formation.
