Points saillants

Low hazard does not mean no hazard.

Winter snow may still be encountered in the high alpine, travel accordingly.

    1–1.5

    Lingering wind slabs may still be triggered in steep alpine terrain. Assess the snowpack as you go, looking for these stiff deposits of snow.

  • Cornices

    Be aware of large cornices overhead, or as you approach/walk along ridgelines. There were a few close calls last week, with people getting too close and luckily not being taken with the collapsing mass of snow.

Avalanche Summary

There were a few small avalanches in extreme north-facing terrain in the highway corridor on Friday and no new reported on Saturday

Last Sunday there was one skier accidental Sz 1.5 on Youngs Peak and a close call from a natural Sz 2 on Ursus Minor.

Cornices remain a concern with two close calls last weekend on Youngs Peak and along the ridgeline of Cheops

Snowpack Summary

Below treeline, you will find a well-settled spring snowpack, with a strong surface crust that may break down during the heat of the day.

The treeline snow depth is a record low of ~210cm. A variable crust exists on all but high northerly aspects, which may still hold dry snow.

The Feb 3rd crust/facet layer persists at upper elevations, buried 80-140cm down.

  • Be carefull around freshly wind loaded features.
  • Remember that the snowpack will be significantly different at higher elevations than lower down.
