Highlights

Wind slabs are sensitive to human triggering. Some good skiing can be found in sheltered areas at Treeline, but prepared for a thrash to get there as the low elevation snowpack remains quite shallow.

    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–3
    Strong winds and recent snow has led to fresh wind slabs in the Alpine and Treeline. These slabs will be sensitive to human triggering, especially in convex or unsupported terrain..

  • Loose Dry

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–2
    Recent snow and strong winds has led to frequent sluffing in steep Alpine terrain on all aspects. Ice climbers should be aware of overhead hazard.

Snowpack Summary

Up to 25cm of recent storm snow is sluffing in very steep Alpine terrain. Moderate to strong winds were forming wind slabs today in the Alpine and in isolated locations at Treeline. These recent slabs were not reactive to skier traffic today, but this appeared to be changing for the worse as we left the field. At 2200m the Nov 12 crust is buried 50 to 60cm and was not reactive in numerous stability tests.
