Avalanche Problems

• Wet slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW between 500 masl and unknown masl

• Loose wet avalanche • Loose snow • Spontaneous release • 3 - Large • Many steep slopes N, NE, E above 500 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 1 - Small • Some steep slopes N, NE, E above 700 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 4 - Very large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

Avalanche Problems

• Wet slab avalanche • Buried weak layer of faceted snow near the ground • The overlying slab is soft. • Difficult to trigger • N, NE, E, SE, S, SW, W, NW • Rotten snow (lack of overnight freeze) with wet basal facets at Breikågen E coulouir entrance, 680m and along summit ridge in general. Also observed on Store Kågtinden West shoulder at around 700m yesterday in shallow snowpack. Glide cracks at at 500m visible in low-angle terrain along normal ascent route, E-NE asp.

Avalanche Problems

• Loose wet avalanche • Loose snow • Easy to trigger • 2 - Medium • Some steep slopes S, SW

• Wet slab avalanche • Water pooling in/above snow layers • Within half a meter • Very difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW • Fant vannmettet lag i tilknytning til skatelag i annen profil
