Snowmobiled out to ski some chutes @ 10k elevation. Snow turned soft at around 9300'. 4-8 inches of new snow in areas. Found a very small storm slabs form the recent snowfall under the cliffs. Snowpack near top was almost entirely faceted under the recent snow and thin sun crust. Hand pits all above 9300' showed the same layers, 4-8" of new, sun crust, then facets to the ground.

Skied the two couloirs on the right. Great snow in each
