Avalanche Problems
Persistent Slabs
Persistent slabs between 90 and 150cm deep are very touchy and skier/riders/climbers will almost certainly trigger these slides in terrain that has not previously avalanched.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely - Very Likely
Expected Size: 2 - 4
Deep Persistent Slabs
Persistent slabs and wind slabs, once triggered, are stepping down producing large and destructive avalanches. This layer has been dormant for much of the winter, but it is awake and quite grumpy now.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 4
