Recent snow and wind have formed slabs that may be reactive to human triggers at treeline and above.
Use small low consequence slopes to test the bond of the recent snow.

Avalanche Summary
Numerous rider triggered wind slab avalanches up to size 1.5 were reported on primarily northerly aspects at treeline and above on Sunday.
Additionally, numerous rider triggered size 1 dry loose avalanches were reported at all elevations.
Snowpack Summary
15 to 25 cm of snow overlies a variety of surfaces including a weak layer of small surface hoar in sheltered areas and/or a thin sun crust on solar aspects.
The widespread crust buried in early February is down 30 to 50 cm. The snow has been reported as bonding well to the crust in most areas.
Various weak layers persist in the mid to lower snowpack, however, triggering these layers is unlikely where they are capped by a thick crust.
Weather Summary
Monday Night
Partly cloudy. 25 to 35 km/h northwest ridgetop wind. Treeline temperature -8 °C.
Tuesday
Mix of sun and cloud. 15 to 25 km/h north ridgetop wind. Treeline temperature -9 °C.
Wednesday
Sunny. 5 to 10 km/h east ridgetop wind. Treeline temperature -12 °C.
Thursday
Sunny. 30 to 40 km/h east ridgetop wind. Treeline temperature -12 °C.

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Use small low consequence slopes to test the bond of the new snow.
- The best and safest riding will be on slopes that have soft snow without any slab properties.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
