Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size

    Watch for wind slabs near ridge lines, lee features and cross loaded gullies.  Ice climbers be able for these concerns above and between pitches on routes.

  • Deep Persistent Slabs

    • Alpine
    • Treeline

    This crust is mostly found on or near the ground. This layer has not been active lately, but there is potential for slab avalanches on this layer given the current snowpack structure.

Avalanche Summary

No new natural avalanche activity was observed. 

Snowpack Summary

Not much is changing out there right now.  Surface hoar is developing on the surface of the snowpack up to treeline to 4mm.  Pockets of hard slab should be expected in gullied features and in the alpine along ridgelines.  Overall the snowpack is shallow and facetted and lower than normal for this time of year.  The Oct 26th crust is our prime layer of concern down 30-50cm.
