Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes between 1100 masl and 600 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Varierende vind gjør at problemet kan finnes i mange himmelretninger. Gunstig temperatur gjør at fokksnøflak stabiliserer seg raskt. den siste snøen kan være lett å påvirke, men skred her vil bli små.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes • Usikker på utbredelsen av problemet. Sannsynligvis mest aktuelt fra tregrensen og opp mot 1000 moh. Her er kantkornet innad i gammel smelteskare.
