Avalanche Summary

A few small dry loose avalanches were reported on Saturday from sunny slopes.

On Friday, a few small loose dry avalanches were reported in the Duffey area, along with a size 1.5 skier-triggered wind slab in a steep rocky area.

Snowpack Summary

Upper elevations have had some wind-effect and wind slabs may be found near ridgetops. Steep sunny slopes may be moist or have a thin surface crust, shady slopes are facetting or growing surface hoar.

30 to 50 cm of settling snow overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar. This layer only seems to be a problem where the snow has consolidated into a slab overtop, such as in wind-affected areas.

The mid and lower snowpack is well-settled and bonded, with no other layers of concern.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
