Topped out on Emma's ridge line and immediately noticed a recent natural slide. With bad viz this looked to be just a small pocket(40-50 ft) that ripped out (likely a repeater) on very common slide path on the Silver fork Headwall about 3 ft deep. We proceeded to drop in to west bowl out of reach of todays hazard and upon getting to the bottom found the slide had actually extended across a good chunk of the headwall extending over to down and out (about 800-1000 ft). This took out the majority of the due north facing slope. The slide ran all the way to the flats with debris pile an estimated 7-10+ ft deep. Average crown height seemed to be about 3' with some spots that appeared to be 5-8+ ft deep. Wind slab that appeared to step down in some spots around the cliffs to basal facets.
