Points saillants

Avoid steep wind-loaded features, rider-triggered avalanches remain likely in leeward terrain.

    Avoid freshly wind-loaded slopes. While the likelihood of naturally triggered avalanches has diminished, but we expect wind slabs to remain reactive to human triggering for several more days.

Avalanche Summary

Field observations have been non-existent in the last week due to periodic closures of the Haines road.

If you make it into the backcountry, please submit your observations to the Mountain Information Network.

Snowpack Summary

Expect 30 to 40 cm of soft snow on the surface in areas sheltered from the wind. Moderate to strong easterly and southerly wind has likely formed deeper, more reactive deposits in leeward terrain. The recent snow covers old, firm, wind-affected or wind-scoured surfaces.

The midpack is generally strong and bridges the weak crystals at the base of the snowpack.

Terrain and Travel Advice
