Regions: Little Yoho.

Great supportive ski quality with little wind effect into the alpine. Move cautiously into bigger terrain features as we have limited observations from the region, and the weak layers not well defined as of yet. SH

Weather Forecast

Highs of -15 at both 2000m and 3000m with light gusting moderate winds and trace amounts of snow later in the afternoon.  Sunday and Monday look cooler with alpine temperatures around -20C and continued light winds.

Snowpack Summary

At TL and below 50-60cm of snow lies over a layer of facets and surface hoar formed mid Jan., producing moderate sudden planar results today on Mount Field. Below lies a mainly faceted snowpack. In the alpine a layer of facets can be found down 80-100cm with a stiff snowpack above and below. Areas closer to the Wapta have a more settled snowpack.

Avalanche Summary

No new avalanche activity noted today, but signs of a previous avalanche cycle were evident on Mt. Field to size 2.5.

Confidence

Due to the number of field observations

Avalanche Problems

Persistent Slabs

Be conservative with your terrain choices, especially when entering larger, steeper features. Dig down to see where the Jan. weak layer is and how it is reacting locally. We are still unsure about distribution of this layer within the region.

  • Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 3
