Avalanche Summary

No recent avalanches have been reported. Observations are becoming more limited as we enter into spring. If you're out in the mountains, please consider posting your observations to our webpage using the Mountain Information Network. 

Snowpack Summary

Melt-freeze surface conditions exist on sun-exposed slopes. On shaded slopes, 10-20cm of recent snow overlies a thick supportive melt-freeze crust. At higher elevations these accumulations may have been blown around by variable winds and thin wind slabs may exist on a variety of aspects. The mid-March crust/facet complex is buried around 50cm below the surface. This layer is generally considered dormant, although it could be reactivated in isolated terrain by prolonged warm temperatures. The mid and lower snowpack are strong and well settled.
