Snowpack Summary

Towards the Icefields, the alpine is wind affected. The Jan 18 surface hoar layer (down 40cm) has faceted away in most places, but shows isolated sensitivity at treeline and below in the Ice fields region. The midpack is mainly supportive, over depth hoar in shallow areas. Although structurally weak, this layer has been generally dormant lately.

Avalanche Summary

No avalanches were observed in the Eastern part of the park today. The snow pack continues to facet with cold temperatures.

Avalanche Problems

Wind Slabs

Watch out for pockets of windslabs in the alpine in immediate lee's

Use caution in lee areas. Recent wind loading have created wind slabs.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5

Deep Persistent Slabs

Although the basal weakness (depth hoar) is generally dormant, with no recent natural loading of the snowpack, these may still be possible in isolated places. Steep, unsupported, and thin depth are factors to be wary of, as are cornices overhead.

Be cautious in shallow snowpack areas where triggering is more likely.Minimize exposure to terrain traps where the consequences of an avalanche could be serious.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 1.5 - 3

Loose Dry

Isolated to steep terrain where surface snow doesn't show signs of previous wind affect : all elevations at the north end of the bulletin region, but only lower elevations in the Columbia Icefields region

Minimize exposure to terrain traps where the consequences of an avalanche could be serious.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
