  Primary Concern Comments: Only went on ridge but small soft slabs were reactive to ski cuts. Not large enough to be a problem yet due to lack of SAFT.

BOTTOM LINE
 Comments: Small soft slabs were forming and easily triggered with ski cuts starting at 9500' but were not large enough yet to be a real problem. FCsf found down 15cm will be something to keep an eye on for the future. Need some more snow with the current winds to really see some action.
