Mechanical mixing (pedoturbation) in soils can be caused by a variety of agencies and conditions. This paper proposes that water under artesian pressure below a frozen soil zone may be a cause of soil mixing as the frozen layer thaws in the spring. Thawing occurs at both the top and the bottom of the frozen soil zone. Points or areas of weakness in the frozen soil zone develop and become sites at which subsurface water breaks through the frozen zone. Artesian pressure, below the frozen zone, causes water and soil materials to move upward. It is proposed that among the consequences is the mixing of the soil in and above the frozen zone.
