Avalanche: Gods Lawnmower

On my way down canyon around 4pm, I noticed a pocket of snow had pulled out from below the lower cliff band of the Lawnmower and some debris fanned out below. The full width of the slope above had obvious signs of graupel movement/pooling but this was the only crown I could see. The debris seemed to me to be more voluminous than what the pocket could produce. I wonder if the clouds obscured a larger crown higher up on the slope. Timing could've been this morning or maybe during higher PIs in the early afternoon.
