Ice-wedge casts in northern Nova Scotia and the relation of the casts to the outwash that contains them indicate that the ice wedges formed in a permafrost environment after the accumulation of the outwash. This permafrost environment is tentatively correlated with pollen zone L-3 of the Gillis Lake deposit, Cape Breton Island, Nova Scotia, and with the Valders time of the midcontinental sequence.
