Avalanche Summary
There was no avalanche activity reported on Wednesday or Thursday.
On Tuesday there was size 3 natural persistent slab avalanche reported on Hudson Bay Mountain on a northerly aspect in the alpine. It was suspected to be triggered by intense wind-loading. Read this MIN post for more details.
Snowpack Summary
Approximately 10 to 15 cm of new snow has buried a widespread crust. Strong winds earlier this week have likely scoured surfaces down to the crust in most windward-facing terrain while forming deeper deposits of snow in lee terrain.
Previously problematic layers deeper in the snowpack appear to have bonded and strengthened, however, there is a low likelihood that they could remain a risk in steep, north-facing, alpine terrain.

Terrain and Travel Advice
- Start with conservative lines and watch for clues of instability.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Brief periods of sun could quickly initiate natural avalanche activity.
