Today we rode up to the BWRA to look for avalanche activity from last night’s storm. There was around a foot of new snow from the storm. Skies were clear, temperatures were warm, and winds increased from light to moderate out of the west in the afternoon. We observed active blowing snow and wind loading near and above tree line in the afternoon. We observed several D1-D2 wind slabs generally above tree line on NE aspects that ran naturally during the storm last night. One wind slab on a NE aspect around 10,000 ft in “Rip It Bowl” was over 500 feet wide, SS-N-R2.5-D2. We also observed a couple of storm slabs up to D1.5 on lower more wind protected slopes that ran naturally during the storm. During our travels near and below tree line the recent snow only produced minor cracking and seemed to be stabilizing after last night’s natural avalanche cycle. The sun was out in force today and southerly facing slopes heated up significantly. We were able to initiate small loose wet “push-alanches” in the afternoon on a SE slope near tree line. In southerly terrain today human triggered loose wet avalanches likely would have been a hazard in extreme terrain. We also observed two old persistent slab avalanches on North aspects around 9,200 ft on “Sardine Can Wall” that likely ran during the powerful storm in the last week of January. The crowns had settled significantly but were still around 2 feet deep. They ran on large grained facets near the ground. SS-N-R2-D2-O.
