Snow Surface Conditions: 
Dense Loose
Snow Characteristics Comments: 

Found some great snow today with the heavy supportable snow from Tuesday topped off with about 4" of light density colder snow.  Stayed out of wind affected snow in protected high areas.  The snow seemed to have settled out significantly since yesterday to today, ski pen up to 14" yesterday, today more in the 4"-6" range.

Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Poor Snowpack Structure
Avalanche Problem #1
Persistent Weak Layer
Problem #1 Comments: 

Although none really observed today the structure is still there to produce potentially large PS avalanches, with additional wind loading this may be activated into a natural cycle.

Avalanche Problem #2
Wind Drifted Snow
Problem #2 Comments: 

The winds from yesterday and light winds today had transported some snow and formed some wind slabs.  Most of the ones I observed were stubborn.  New wind slabs could form with increases winds and 4" of light density snow available for transport.


Really surprised to see almost no tracks and no avalanches in the whole lake Catherine basin, as well as no distinguishable avalanches in all of wolverine cirque.  Much deeper pack in this area than anywhere else I have observed, from HS 130 to 180cm between 9,800' and 10,800'.  The deepest around and above Lake Mary in protected areas.  Found lots of little steeper small test slopes that were surrounded by rocks with rocky bed surface and couldn't get any snow moving other than the 4" of fluff on top sluffing on steepest slopes traveled.  The structure is still there and set up to produce PS avalanches despite all this.  

No observed natural or skier triggered activity in Wolverine Cirque.


Where I was today I thought the hazard was moderate with pockets of considerable.  I did not touch or test any longer slopes (ie Wolverine cirque chutes or similar) because I figure let the snow snow sit there and settle out rather than just clean it out and ruin potential future ski runs.
