Avalanche Summary

There were no reports of avalanche activity Sunday and Monday.

On Saturday, skier triggered storm an wind slabs were reported up to size 1.5 at and below treeline.

Snowpack Summary

Many areas have received 20-50 cm of localized convective snowfall over the weekend, bringing weekly storm totals up to 60 to 100+ cm. The recent snow sits over a crust on all but high north aspects. At upper elevations recent snow has been redistributed by wind.

Below the crust, the snowpack is generally well consolidated. A facet/crust layer in the mid snowpack was put to the test by the significant new snow load and it does not appear to present an avalanche problem at this time.

Below treeline areas have now received enough snow to produce avalanches. Watch for "early season" type hazards such as shallowly buried stumps, rocks and creeks.
