Regions: Glacier.

Good riding can be found in the alpine while excellent edge dulling rock grinds and knee bending alder bashing opportunities exist below tree line. Leave enough time near the end of your day to make a safe exit before it gets dark.

Weather Forecast

An upper ridge is deflecting any organized weather system from reaching our region. This is allowing a cool arctic air mass from the North to slip Southward, spreading cold and dry conditions over BC. A mix of sun and cloud for the day with an alpine high of -12 with light Northerly winds. Cold temps and clearing skies for the week.

Snowpack Summary

40cm of snow covers a surface hoar or suncrust layer at tree line and sheltered alpine areas. Winds have created a soft slab on this layer in specific lee or cross-loaded features. The October 26th crust near ground may be poorly bonded on some high elevation north aspects.

Avalanche Summary

Several thin slab avalanches (15-20cm thick) to size 2 were observed from steep South aspects, while loose dry point releases to size 1.5 were seen coming from steep North aspects over the last few days.

Confidence

Avalanche Problems

Persistent Slabs

This layer is widespread and most pronounced at treeline elevation. It will be most reactive in areas where wind loading has occurred and encouraged slab development.
Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
