The alpine rating is Deep Persistent Slabs., the treeline rating is , and the below treeline rating is Known problems include
Don't let tracks on a slope lure you into bigger terrain.
This problem is best managed with patience.
No reports from Wednesday at the time of publishing.
On Tuesday there were two skier-triggered deep persistent avalanches (size 1.5-2) west of Invermere in shallow areas. Both times there were tracks on the slope and the skier who triggered it was caught, buried, and recovered uninjured. (one partial burial, one full)
Several small, dry loose natural avalanches occurred on south aspects.
On Monday, three size 2 avalanches were triggered by skiers west of Invermere.
Recent snow continues to settle and bond. This new snow is sitting atop old wind-affected snow and weak, faceted grains.
The mid-snowpack is generally made up of faceted snow and various old crusts.
At the base of the snowpack, weak faceted grains and depth hoar are present, particularly in alpine terrain.
Partly cloudy with a trace of new snow, southwest alpine winds 10 to 20 km/h, treeline temperature -6 °C.
Mostly cloudy with a trace of new snow, west alpine winds 10 to 20 km/h, treeline temperature -5 °C.
A mix of sun and cloud with a trace of new snow, southwest alpine winds 20 to 30 km/h, treeline temperature -5 °C.
Mostly cloudy with a trace of new snow, southwest alpine winds 20 to 40 km/h, treeline temperature -3 °C.

Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
Deep Persistent Slabs
If triggered, this problem will likely be the full depth of the snowpack. Avoid shallow, rocky start zones.
Aspects: All aspects.
