Rockwall permafrost is increasingly investigated because of its possible role in bedrock failure, related hazards and geotechnical practices. In this study, we simulate the possible permafrost pathways during the 21 st century of one of the coldest rock ridge in the European Alps: the Grand Pilier d...
