Comments
A skier triggered sluffs at 40dg. The sluffing area was significantly wider (100m?) that the observed crown (no pic atm), fairly slow moving. The run of the avalanche was shallow. The crust was certainly reactive at around 1700-1800m with about 5cm slab on top of it. Conditions were better in higher elevations with no activity observed except older wet loose slides on rocks and sunny spects. The slab broke at a concave (not convex) feature, probably a wind loaded pocket. The avalanche did not step down to deeper layers. No burial, no injury.
