Avalanche Summary
On Thursday the field team saw no new avalanches in the Crowsnest area. On Wednesday there were some small isolated wind slabs reported from reverse loaded features on the Alberta side of the region. On Tuesday the field team reported evidence of a natural wind-driven avalanche cycle (likely from Monday), with avalanches in the size 1-2 range in the northern Elk Valley.
Snowpack Summary
The 10-30 cm of most recent snow has been redistributed by wind from various directions over the last week and formed some wind slabs in unusual places. This latest load sits over old firm wind-affected snow in open areas and hard sun crusts on solar aspects.
The snowpack below is generally well consolidated, with a crust/facet layer found near the bottom of the snowpack. It is currently considered dormant but could become active later this season. Check out the forecaster blog for more information.
Terrain and Travel
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Be alert to conditions that change with elevation and wind exposure.
Problems

Alpine features are the most likely culprits for wind slabs, but exercise some caution in exposed treeline features with stiff snow as well.
