Problems
Wind Slabs
Watch out for lingering wind slabs down into exposed tree line features.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Cornices
Be mindful of what is above you when the sun comes out and the temperatures start to rise.
- Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.
- Cornices become weak with daytime heating.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
Likelihood
Expected Size
Loose Wet
Expect small wet loose avalanches off steep rock features with increasing temperatures and solar input.
- Use caution above cliffs and terrain traps where small slab avalanches may have severe consequences.
Aspects: East, South East, South, South West, West.
Elevations: All elevations.
