Loose Dry
Watch for changing surface conditions when slopes start receiving sun. As the snowpack warms loose avalanches are possible, especially on steep slopes. Rocky outcrops are prime trigger spots. Limit your exposure to slopes adjacent to hot spots.
Aspects:
North, North East, East.
Elevations:
Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
Cornices
Large cornices exist on many ridges in the park. We have observed them failing recently in part due to solar warming. Large cornice falls can trigger deep weak layers. Use extra caution on corniced ridges, they can fail far back from the ridge crest.
Aspects:
North, North East, East, South East, South.
Elevations:
Alpine.
Likelihood: Possible
Expected Size: 1 - 3
Wind Slabs
Wind slabs formed on lee slopes during the last storm period due to strong southerly winds. They are found at ridgecrests and cross-loaded features. Watch for hard wind pressed snow and exercise caution on steep, unsupported features in the alpine.
Aspects:
North, North East, East, South East, South, South West.
Elevations:
Alpine.
Likelihood: Possible
Expected Size: 1 - 3
