More detailed information about the avalanche: 

As we skinned up the ridge to about 10,200' on the ridge between Red COne Bowl and Hollywood Bowl, we saw the crown of a recent wind slab avalanche on a NNE aspect leading down into Hollywood Bowl.  It appeared to be skier triggered, but did not look as if anyone was caught by evidence of the tracks leading into, next to and out of the slide.  I would estimate that it happened within an hour of our arrival, as there was very little new snow accumulation on the bed surface.  Due to visibility, it was hard to tell how far out into the bowl it propogated or traveled.  The depth of the crown was ~40cm and I would estimate its destructive potential as D2.
