Abstract

Glacially deformed permafrost at North Head, in the Tuktoyaktuk Coastlands, contains a complex ground-ice stratigraphy that formed during the course of the last glacial-interglacial cycle. Two generations of ground ice are distinguished within a single stratigraphic sequence. The superimposition of post-deformation intrusive ice and massive segregated intrusive ice into permafrost containing pre-deformation ground ice indicates that substantial quantitites of overpressurized water were injected into ice-marginal permafrost during or after deglaciation. This required external water was probably overpressurized subpermafrost groundwater in front of the retreating margin of the Late Wisconsinan LIS
