Cautious route finding & conservative decision making is essential.
Human triggered avalanches are expected, especially in areas where people haven't skied.
Remote and rider triggered persistent slabs avalanches are occurring daily.

- Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
This week field teams have remotely triggered numerous size 1 to 2 persistent slabs from low angle terrain at tree-line and below. These have been 40-60cm deep, failing on surface hoar layers in the upper snowpack.
In the Bostock drainage two separate size 2 avalanches were triggered from 10 to 40m away breaking small trees.
On Monday, a sz 2 avalanche in Cougar Creek East caught and injured a rider.
Up to 60cm of new snow fell this past week. Ridge-top winds created slabs in immediate lee features.
The Feb 9 surface hoar (SH) is buried at the bottom of this new snow (40-60cm down) and is reactive in tests.
Recent Spring-like temps and sunshine created several crusts in the upper snowpack, upon which the Feb 9 SH sits.
The Jan 26th layer, composed of surface hoar/facets/crust, is buried down 60-80cm. The largest surface hoar is preserved in sheltered areas below treeline.
- We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.
