| Abstract | A low peat plateau in the alpine forest-tundra at Mont du Lac des Cygnes, 100 km northeast of Québec City, contains a permafrost body 2 m thick. At an elevation of 960 m, this is the southernmost known
occurrence of alpine permafrost in eastern Canada. The terrain over the permafrost is windblown and bears a very thin and discontinuous snow cover. One year of continuous temperature records indicates that the mean annual air temperature at this site
is about 1.3 °C. The permafrost remains at temperatures very near the freezing point for most of the year. |
