Summary(Plain Language Summary, not published)
Thawing of ice-rich permafrost, which can be caused by climate change or development on permafrost, can be hazardous to northern infrastructure. Here we present an approach to better understand the distribution of permafrost landforms and their relation to the variety of terrain types found along the Dempster and Inuvik to Tuktoyaktuk highway, the only road access to the Canadian western Arctic. Mapping results show that the majority of landforms identified as ice-rich, such as ice-wedge polygons, are concentrated in the Arctic physiographic regions, indicating the high thaw sensitivity of these terrain units. These data can be used in developing models to assess the thaw susceptibility of permafrost terrain.
