Kernpunkte

Triggering avalanches will be unlikely on Saturday. Continue to watch for signs of unstable snow and use safe travel techniques, like riding one at a time on slopes that are steeper than 30 degrees. 

Avalanche Discussion

Overall, the snow surface is highly variable, as it has been for the past week. On Friday, the sun warmed south-facing slopes enough to soften them in the mid-afternoon, but it was too cold for a loose wet avalanche problem. Likewise, moderate wind gusts at ridge tops can get a little snow moving, but there is not enough soft snow available for transport to create wind slabs. Some shaded terrain below treeline still holds 10-15 centimeters of soft snow. 

On Thursday and Friday, surface hoar was observed in cold, shaded areas at Newberry and in the Cascades. Surface hoar is a type of snow crystal that looks feathery and sparkly, and it can get quite large. It can become a weak layer if it gets buried in its upright position, but for now, it doesn't pose a hazard.
