Abstract

Small hydrolaccoliths (ice-cored mounds occur within low ice wedge polygons on poorly drained meadow tundra) soils in the masik Valley, Banks Island, Canada. It is suggested that the process of ice segregation is brought about by a contraction of the water-saturated layer under cryostatic pressure and that the upstanding ice wedges, which bound the polygons, form the boundaries to the closed system. There is some similarity, therefore, between these features and the closed system pingos of the Mackenzie Delta with respect to genesis.
