Avalanche Summary
No new avalanches were reported on Monday or Tuesday before 4 pm.
On Sunday in the Mt. Cain backcountry, there were reports of whumpfs and a large avalanche around treeline.
Snowpack Summary
Many areas 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, the 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 tested by the significant recent 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.
