The stability of steep slopes and rock walls is a major point of concern in relation to a changing climate, and is important for society, transport and more. Permafrost is a factor which can stabilize steep sloops. Rock wall permafrost has been intensively investigated in mountain areas like the Alps, but there is little knowledge about the topic in Norway. CryoWALL aims to investigate permafrost on rock walls in Norway.

The Cryosphere includes all frozen water on the Earth's surface, all areas where snow, ice and permafrost affect the landscape and processes occurring there. We find a big amount of water tied up in glaciers and icecaps in Arctic and Antarctic, but also in permafrost and smaller glaciers worldwide.
