permafrost either within 1 m of the surface or within 2 m if the pedon has been
strongly cryoturbated laterally with the active layer. The Crysolic order was divided
into three great groups: Turbic cryosols, Static cryosols, and Organic cryosols, based
on the degree of cryoturbation and the nature of soil material (Table
6.4
). This system
has undergone two subsequent revisions, and a fourth revision is in progress.
