Regions

Yukon, Tutshi, Wheaton, White Pass East, White Pass West.

Head to sheltered areas to find the best riding conditions and avoid wind affected snow.

Continue to assess conditions as you travel.

Avalanche Summary

No avalanches have been reported in the last 3 days. Wind slabs may still be triggerable by a rider in isolated areas.

Snowpack Summary

Alpine surfaces are heavily wind-affected, but soft snow can still be found in wind-sheltered terrain. Check out this White Pass MIN for more.

A spotty layer of surface hoar may sit below recent snow, buried around 20 to 30 cm deep. Below 1500 m, a thick melt-freeze crust is buried 50-100 cm deep.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Make observations and assess conditions continually as you travel.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
