Spotted this from the powder park 1 Ridgeline. Snow cover would imply it happened sometime during the last storm. Large enough to easily bury a person and the slide appeared to trigger sympathetically across a rock band. It was very difficult to photograph, but the crown extended beyond the photo and around the head of a gully. The crown was 1-2 feet, likely the faceted layer. No tracks were seen on the slope so it is assumed to be natural.
