An inch or two of new snow could be found in the surrounding environs of Mission Ridge on Monday. Although the wind had drifted it around into some slightly deeper drifts, I didn't find anything large enough for a wind slab. Under the new snow, old surfaces are variable depending on aspect and elevation. Soft and weakening surfaces made for some nice skiing on sheltered east and north-facing slopes.
The coverage is good in the Stemilt area, with snowpack depths ranging from about 100cm to 150cm. The weakest snow I found was in the 5,500ft elevation band, with a thinner snowpack that has continued to facet out. Some areas were so weak that I could punch through to the ground with a ski pole basket. The Mid-January crust can still be easily identified, and harbors weak snow underneath it. This layer bears watching with additional snowfall or warming events.
I observed an older, D2 avalanche that may have been triggered by a snowmachine in Owl Creek, just west of Mission Ridge Ski Area. This was at around 6,000ft on an east aspect, and I'd suspect the Mid-January crust as the weak layer.
