Small snowboarder triggered windslab below frog lake

Lots of wind and blowing snow below frog lake at Carson pass. We stuck to the trees but a snowboarder in our party triggered a small windslab while descending a little rollover as you entered the trees just below rocks where we transitioned well below ridge line. Snowboarder rode away without issue. Crown was about 8 inches at deepest. 

I was able to kick off a similar sized windslab at ridge line at the edge of a small cornice and open areas had pockets of wind deposited snow in the area. Mostly overcast with light snow and windy between 10:30 from Mid moring to mid afternoon while we were there.
