Avalanche Problems

Loose Wet

Expect a higher probability of naturally occurring moist avalanches in and around steep gullies, and rocks, during the heat of the day. These loose snow avalanches have the potential to trigger windslabs and deep slabs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

These deeper layers can wake up unexpectedly. Natural avalanches continue to fail on deep layers. Profile Saturday found Feb14 surface hoar buried 80cm, unreactive yet present.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4

Wind Slabs

Slabs are present on exposed slopes and steep gully sidewalls. A significant wind slab release was noted Friday off Mt Kitcheners ridge facing the Icefields center. It was 50cm deep, 38 degrees or less in places, and ran a fair distance.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
