Highlights

Highwood pass has now closed for the season! Natural avalanche activity has ceased but still use caution for recent windslabs that were building in alpine areas.  In thin areas you may trigger the basal weakness. MK

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–3
    Expect windslabs in lee and cross loaded gullies. These problems are easy to locate in the alpine and more isolated and harder to find at treeline areas.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3
    The new crusts are preventing the deeper layers from disturbance. Remember, in shallow areas it is still possible to trigger the deeper layers.

Avalanche Summary

No new avalanche observations were seen in the past 24hrs. 

Snowpack Summary

Windslab can be found in alpine terrain up to 40cm thick along ridelines and in cross loaded features.  These problems are most easily found on N and E aspects.  The "Midpack" consists of a series of crusts from rain events in november.  These crusts are down 50 and 80cm but so far, no results have been observed on these layers.  Deeper down the October Halloween crust has been producing Hard sudden collapse results.  Thin areas will be the most likely areas where a skier may be able to trigger this weakness so heads up for thin snowpack areas.
