Small palsas with very thin frozen layers are present within the peat deposits east of James Bay. Most of these permafrost landforms are in an advanced stage of decay within raised bogs between 51°45′N and 55°N. Air photographs, air-borne surveys and ground-truthing of permafrost indicate a recent northward recession of the permafrost boundary by about 130 km, most of which likely happened in the past 50 years.
