Calm and warm morning followed by windy and cold afternoon

On our ascent towards the Alpine Mine, it was clear, warm, and calm. We observed new surface hoar at the surface, and some near surface faceting. Surface hoar was more prevalent on lower angled slopes, and near surface faceting on steeper slopes. No wind transport was observed in the morning. We came across a previous avalanche likely from late last week/weekend. The crown was still angular even though it faces the recent east winds, so I suspect this was one of the later avalanches in the avalanche cycle. We dug profiles near the flank, and found buried surface hoar at the right depth to be the failure layer of the avalanche. Numerous snowpack tests did not indicate current instability on this layer. After noon, east winds picked up and the temperature dropped. When our tour ended, from my truck I observed wind transport of snow along ridgetops. The east winds appeared to be so strong that snow was being blown well up and above terrain features, and probably not depositing it near the tops of leeward slopes.
