More detailed information about the snowpack: 

Toured Rock Creek road to assess snow coverage and get familiar with the local snowpack and snow history. 

Abundant scour and limited coverage. Even wind loaded gullys on east faces of Star and Pointless as well as the west facing morraine of Morgan looked bony. Evidence of storm sloughs frequent within gullies. 

Explored the snowpack in a protected west facing area and found it to be unconsolidated and sugary overall. New snow easily slid with CT1 SC but very unconsolidated. The melt-freeze crust was relatively weak (1f), but I was still able to get CT11 SC failure below the crust repeatedly.  No signs of any propogation. 

This protected spot made it seem that the snow was only sticking to the ground because of the vegetation and low angle.  I did see signs of storm sloughing and much of the scour was to bare ground.

Coverage did not inspire further investigation, but it seems there could be a problem with faceted snow under windslab if one was able to find a gully with enough wind loading to ski.
