Head to sheltered terrain for the best riding conditions, wind slabs remain reactive to riders.
Monitor surface conditions as you gain elevation and move into wind affected terrain.
Reactivity is expected to continue on convex rolls, near ridgelines and on cross loaded slopes.
Wind slabs could step down to buried crusts, most likely to be triggered by large loads at or above 1900 m.
Wind affected snow continues to be reactive to rider traffic. Recent avalanches reported have not involved the crust buried up to 100 cm deep.
Slab avalanches were triggered in the alpine on north facing slopes on Sunday, with wide propagation in steep ridgeline features. See photos below and it's worth checking out this great MIN report from Matier on Sunday for full details and more photos. Thanks for sharing.
Wind affected snow sits above a crust which is found up to 1900 m.
Another crust is buried 60 to 100 cm deep, and in sheltered terrain a layer of surface hoar may exist just above it. There is uncertainty over its reactivity. It is more likely to be a concern in wind affected, thin and rocky start zones at higher elevations.
Snow depths at treeline vary between 90 to 160 cm.
Monday NightMostly clear skies. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -10 °C.
