we saw a slide that had an unknown trigger down into main days off the ridge, but it was just a surface without much punch/distance (probably 40' wide, dirty 1' crown, ran a couple hundred feet).  there was some "hangfire" adjacent that we couldn't really control via ski cut so we didn't tease it.  It was pretty breezy in the morn with a  bit of transport, and I'd guess that this was a result of that.
