On a second run in upper silver fork, a snowboarder triggered a slide near the ground. The slide ran the length of the run out zone and about 150 ft wide. The start zone was below a cliff band in a steep rocky, north facing area. There were existing tracks, and a skin track on either side of the starting zone with two groups in the area. Each group was able to retreat to a safe zone as the slide ran out.

The slide triggered when the boarder was half way down the slope. He started on ridge, pointed it into the gully and made a hard turn and it triggered above him. He was immediately alerted of the slide by another member in our party who was watching his run from a safe zone, the boarder was able to point it and beat it out into the flats. The tracks to lookers left were put in by party earlier in the day. Tracks to right were put in two members of the party prior to run that triggered slide. This happened at about 2pm on saturday. There was another party in the gully on the other side of the ridge that skied lookers left after the slide. We booked it up the skin track to lookers right after the slide.
