Project Title

Structure and evolution of permafrost since the Late Pleistocene, Beaver Creek, Yukon

 

Description of the research project

The Beaver Creek Road Experimental Site (62º 20’ 20’’ N – 140º 50’ 10’’ O) sits on the Beaver Creek moraine. This landform was already evolving before the Last Glacial Maximum. In a single square kilometer perimeter, its topography, vegetation, soil and cryostratigraphy have been studied with a geosystemic perspective to detail its catena and related structure. Furthermore, the cryostratigraphy has been interpreted considering the literature to suggest a landscape evolution model. Recent changes at the site were integrated in the model to actualize the geosystem’s evolutive trend. This work has shown that the durability of the permafrost is strongly supported by the wetlands associated to flat lowlands. On the one hand, some moraine hillcrests are still slightly outcropping. There, the limited moisture inhibited the development of peat and intrasedimentary ice (<1 m). On the other hand, the depressions are quite flat and extended. They inherited not only of the crest’s eroded sediments, but they also fixed an important quantity of ice and organic matter (>15 m) by the mean of syngenetic permafrost aggradation driven by the climate and preserved by the ecosystem. At least one thermoerosion event occurred before the last syngenetic aggradation stage (Holocene), but was only a partial one. The ongoing global warming threatens to trigger another permafrost degradation stage on the drainage basin scale. On the field unit scale, the land use is already degrading the local ice-rich permafrost.
