Avalanche Summary

Few loose dry avalanches out of steep alpine and treeline terrain were observed in the Elk Valley on Tuesday.

If you head out in the backcountry, let us know what you are seeing by submitting a MIN report!

Snowpack Summary

Recent snow accumulations vary across the region from 10 to 20 cm. The previous SW wind has formed firm, wind-affected surfaces at upper elevations in the east part of the region, while the surface snow is mostly unconsolidated in the west part of the region.

See the conditions from north of Sparwood here.

At lower elevations, the upper snowpack contains a melt-freeze crust and facets layer, particularly in south-facing terrain.

Snowpack depth varies significantly across the region, from 50 to over 150 cm.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
