- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Avalanche Problem 2: Cornices
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Cornices are growing with fresh snow and strong winds
Travel and Terrain Advice
- Pay attention to overhead hazards like cornices which could easily trigger deep slabs.
Avalanche Problem 3: Wind Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Wind slabs sit on a hard melt-freeze crust on solar aspects, and facets on polar aspects. Assess the bond at these interfaces carefully before committing to to a slope.
Travel and Terrain Advice
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Avalanche Summary
Avalanche control teams in the Icefields area had minimal results today at treeline. One size 2 debris pile was noted opposite the Weeping Wall resulting from an Alpine release hidden in the atmosphere a similar size event opposite Parker Ridge was also noted from the same storm
Snowpack Summary
A variety of slab conditions exist on most aspects and are of greatest concern at treeline and above. 10-20cm of recent storm snow has created a soft storm slab under the influence of Northerly winds. Below this, older slabs up to 50cm thick sit on a sun-crust on solar aspects and facets on polar aspects. Below treeline the snow is shallow.
Weather Forecast
Snowfall amount will decrease overnight as the colder arctic air takes dominance. A clearing trend will emerge on Saturday with light winds shifting from North to West. On Sunday snow flurries are expected with 5cm each day into the new week.

Of greatest concern in the Alpine where winds were most consistently from the North. Cold temperatures will offer some forgiveness but if triggered this might provide enough mass for a step down effect to deeper weaknesses.
