Avalanche Summary
No new avalanches were reported by Wednesday at 4 pm.
If you are headed into the backcountry please consider making a MIN post with photos and observations from the day. The information is very helpful for forecasters!
Snowpack Summary
A few centimeters of snow covers a melt-freeze crust at all elevations. On shaded northerly slopes in the alpine, you may find 15 cm of dry snow overlying a thin crust.
A substantial crust up to 30 cm thick sits 50 to 90 cm deep, well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated.
Treeline snow depths range from roughly 150 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.

Terrain and Travel Advice
- Watch for areas of hard wind slab on alpine features.
- A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
