of cryoturbation, dilatancy, ped forms, and cryodesiccation features, and at the
microscopic scale from compaction, displacement of plasma or skeletal grains, and
pore formation. Cryopedologic processes are utilized in the defi nition of cryosols or
gelisols and at the second highest level in distinguishing whether or not cryoturba-
tion is observed in mineral soils. Numerical models of cryopedogenesis have
focused on specifi c processes such as heaving, formation of segregation, and
cryoturbation.
