Avalanche Problems

Loose Wet

Loose wet slides on steeper solar aspects related to daytime warming and radiation. Wet slides were observed up to 3000m in elevation on Saturday. A few cornice collapses have been recently observed.

Aspects: North, North East, East, South East.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 3

Wind Slabs

Wind slabs from the various wind events earlier this season are easily found on N and E aspects. Steeper unsupported terrain features are still good places to use caution.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 5

Deep Persistent Slabs

Weak layers persist close to ground that if triggered from a weak area could cause a large destructive avalanche involving the entire winters snowpack. These facets are becoming harder to trigger as the snowpack strengthens.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 3 - 6
