We often say, "If there's enough snow to ride, there's enough snow to avalanche."  Here's the access from the Butler Fork trailhead in BCC.  By those metrics, the danger here was Low.  

 Cracked out yet another wind drift.  Note the photo below.  

The wind drift is smooth and rounded as compared to the closer, non-wind loaded area.  Weakness is faceted snow and surface hoar beneath a 2cm friable crust from 12/28.  Have found the crust to be more pronounced in the drainages of Little and Big Cottonwood. 

 Continued from Wilson back toward Reynolds Peak and managed to collapse and crack out nearly the entire east face, albeit in pockets and pieces - each roughly 40' wide and up to a foot deep.  They all moved 2-4" downhill and stopped.

 The Reynolds Peak ridge line, below.  All very wind loaded.
