    Recent avalanche observations suggest wind slabs are still reactive to the weight of a person.

Avalanche Summary

Recent avalanche activity in the region has been reported as natural and skier triggered wind slabs up to size 2 in the alpine and at tree line.

Snowpack Summary

In general, snow surfaces are best described as heavily wind affected with scouring and sastrugi formation noted on many terrain features. Crusts can be found near the surface on solar aspects at high elevations and on all aspects below 1600m. There have been isolated reports of a surface hoar layer from early January buried about 40 cm deep in sheltered areas, although not much is known about its current reactivity. About 70cm below the surface, you'll find sugary facet crystals which formed during December's cold snap. Although avalanches are currently unexpected at this interface, this layer could come back to life with with warming, significant loading or a large trigger at a thin spot.
