Avalanche Summary
A small cornice failed naturally near Fernie on Wednesday.
On Tuesday, several small, loose wet avalanches were rider-triggered on sunny slopes.
Snowpack Summary
30 to 40 cm of new and recent snow overlies predominantly crusty surfaces, except for northerly aspects at upper elevations.
A widespread, hard crust with facets above is buried down 180 cm in the Lizard Range and 80 to 120 cm elsewhere. Steep or convex terrain features with a shallow, thin-to-thick snowpack at treeline and above are where it may be possible to trigger this layer. However, when a thick surface crust is present, human triggering is unlikely.

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the old surface.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
