Since permafrost in steep rockwalls is mainly climatically controlled, the ongoing climate warming potentially strongly impacts frequency and magnitude of rockfalls in high-alpine rock faces in the near future. However, knowledge about the role of permafrost is still limited. This is especially beca...
