Small wind-pillowed feature on the White Salmon glacier was triggered while skiing down. I noticed the snow feel firmer and cut to my right away from the small slab. This slab was caused by E winds cross-loading the midslope.Observed Avalanches

2 crowns from natural wind slab avalanches observed underneath the hanging glacier. According to someone who was there yesterday, one of these released naturally with wind loading around 4 pm on 4/4/23. There appeared to be natural loose dry sluff running during the day today.Signs of Unstable Snow

NoObservations
Skied the White Salmon Glacier. Two groups had skied the NW Couloir the day before and reported large sluffs and a small ~2" surface windslab running in the gully above the exposed traverse.. A few tracks on the WSG from the were mostly blown in as we ascended this morning. Observed transport onto the N face and on the glacier as we climbed. Many steep lines were skied (including 10+ more tracks into the couloir). We only saw one other skier-triggered windslab fairly low (NTL at the tree diamond below the WSG) besides the one I triggered. Loose dry sluff was still running fast in steep areas. Good ski quality on the glacier. Clouds moved in and out in the morning with clearing in the afternoon.
