Today we saw a widespread natural avalanche cycle on facets and surface
hoar. Fortunately, the slab is quite shallow - rarely more than 20 cm
and often less. It propagates very easily with cracks shooting 50 m
across slopes. However, it ran slowly and only in quite steep terrain.
It does appear that another crust and facet layer formed on 28 February
and today's avalanches ran on that. A large avalanche ran off Hut Peak
and dusted the valley.
We are moving very carefully and suspect that more load may activate
lower weak layers.
