Avalanche Summary
On Friday, numerous loose wet size 1 avalanches occurred. Additionally, a skier triggered size 1.5 slab avalanche released from an East aspect at 2250 m. The crown depth was 25 cm, width was 30 m and running 40 m in length.
Snowpack Summary
Up to 15 cm of new snow sits on melt-freeze crusts (solar aspects) and smaller surface hoar crystals on Northerly aspects. Touchy wind slabs have built on lee slopes and behind terrain features and cornices are huge and remain a concern, threatening slopes below.Buried 60-100 cm down, exists an interface of crusts and buried surface hoar. This is mainly found at upper elevations on all aspects. It seems to be slowly gaining strength, yet this interface has recently become reactive in regions further south. I would remain suspicious, especially of large, steep high-alpine slopes. Dig down, and test layer of concern.
