| Abstract/Notes | Active thermokarst processes occur on the hummocky and rolling terrain of eastern Banks Island, in the western Canadian Arctic. The underlying sediments are ice-rich glacial silts, sands, and gravels. Ground ice slumps, triggered by a variety of local conditions, are particularly numerous in the area to the west of Johnson Point. Maximum rates of headwall retreat of between 6.0–8.0 m/y−1 appear typical but many slumps are short-lived and become stabilised within 30–50 summers of their initiation. Rapid thermal erosion along ice wedges gives rise to badland topography in certain areas where ice-rich silts enclose large ice wedges. |
