carefully assess steep lines for wind slab. The best riding is also where the likelihood of triggering avalanches is greatest.

Summary

Confidence

Moderate

Avalanche Summary

A couple of skier-triggered avalanches surprised a ski touring group on Saturday. Both avalanches were reported as size 2 and occurred on a northeast, alpine slopes just below a rocky ridge top.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

5 to 15 cm of recent snow has fallen over firm snow above 1900 m. In sheltered north facing terrain at treeline and above, this new snow is likely soft and makes for good skiing. Below 1900 m, the snow is covered by a variably breakable crust.

The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Closely monitor how the new snow is bonding to the old surface.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
