Avalanche Canada
Although the Danger rating has decreased to moderate, we are dealing with a very young snowpack who is trying to gain strength and our trust. The october layer is still producing repeatable results and should be on your mind when decision making.
Summary
Confidence
Moderate
Avalanche Summary
A small ski and a flight around the Northern part of the spray showed no new avalanches last night or today.
Snowpack Summary
Teams in the field today had good travel conditions. The October/ November crust are keeping the snowpack supportive and the travel good. Where not previously travelled, there is 25-35cm of fresh snow that will be available to be transported by the slight increase in winds.
The Highwood area has had more wind affect than other areas. While it isn't wind scoured by any means, there are some higher areas showing waves and ripples. Interestingly, the loading pattern suggests both north and south flows last night. Expect some cross loading on east and west aspects.
A quick pit at treeline elevation (1950m) showed Height of snow at 67 cm. We did an extended column test and got full propagation on the october crust. See attached snow profile.
Weather Summary
Monday night will be a low of -11 with trace amounts of snow falling .
Tuesday should be a little bit sunnier, Day time highs -10 and a little bit more wind out of the west.

Terrain and Travel Advice
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Keep in mind a buried crust offers an excellent bed surface for avalanches.
Problems
Persistent Slabs
This slab is sitting on the October crust which has facets above it and provides a good sliding surface. More reactive on N and E aspects, Able to get repeatable results with isolated column tests on this layer.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Wind Slabs
Wind direction more variable in the alpine, hence the all aspects. Tree's at Treeline elevation still holding all the storm snow. Windslabs not found in this elevation range at this time.
Aspects: All aspects.
Elevations: Alpine.
