While on the W monitor Ridge line we also witnessed a natural avalanche occur in Dutch's Draw off the Cone which in turn sympathetically released another slide in Dutch's skier left of the first slide. First slide seemed to be triggered from a natural cornice drop. Not sure of the specifics in this slide it was quite a long ways away, but it looked to be a fairly large slide. Aspect was NE, lots of wind transport going on. Also of note were shallow mid-slope slides on the West Willow Ridge Line.
