Likely natural cornice failure triggered slide from saddle above Peanut Butter Bowl. This is separate from mid February slides. Crown extended approximately 100m lookers left and perhaps 300m lookers right across basin. Viewed from a distance. But crown appears perhaps 2 feet deep and likely stepped down to previously suspect facet layer.
