More detailed information about the snowpack: 

Around 2.5' of total storm snow at the Tamarack Lakes trailhead and 4-5' at higher elevations with some wind loading effects.  Observed shooting cracks in some of the moderately wind loaded terrain and cracking was common.  All the small soft slabs that I kicked off were failing within the recent storm snow, about 8'' deep.  Visibility was poor, once I gained the ridge I couldn't see much of anything and couldn't make out any natural avalanche activity.  Very deep trail breaking conditions today and heavy sluffing in lower angle terrain. 

 

Photo#1:  Shooting cracks and cracking were common mid slope and above.

Photo#2:  Soft slab failing with a ski kick at 9200' north aspect.  Not much propagation at this elevation, wind loading was occuring but limited.

Photo#3:  Looking towards the ridge and at treeline terrain, visibility was very limited.
