Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 2 - Medium • Few steep slopes

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 1 - Small • Some steep slopes SE, S between 1700 masl and 1100 masl • Lille blokktest. Brudd skjedde ved stor tilleggsbelastning i kantkorn under skarelag. Q3.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • Possible • 2 - Medium • Few steep slopes E, SE, S above 900 masl • Fokksnø i heng mot S-Ø har fått god tid til å stabilisere seg, så en skal være svært uheldig for å treffe på heng med ustabil lagdeling. Snømengdene i enkelte heng er store nok til å gi skred str 2 er min vurdering.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes E, SE, S above 900 masl • Kantkornlag fins i alle himmelretninger men utgjør et skredproblem bare der det er fokksnø over som kan danne flak, og det er i dag kun heng mot S-Ø.
