Comments
Just wanted to clarify the order of events in Cardiff Bowl today. Our party of 3 skied 1 lap from the pass (SSE aspect). Prior to our 2nd lap a party in front of us had skied/traversed directly under where the slide had happened, about 1/2 way up the East aspect slope but nothing happened. We skied a 2nd lap on a more SE aspect and stopped at the bench in meadow. Decided the skiing was great so we would convert there and do one more. As we were converting we noticed a party skinning/traversing through the bowl inching around the compass to east aspect. They got up to the ridge and sort of went out view. We were just about to start skinning back east to main skinner and the slope broke so we scurried to high ground in the trees. Toe of the debris stopped about 15 feet from us. No propagation evident from the ridge or from meadow. No slab in meadow so we assumed it was from the party on the ridge. Good free lesson to convert in safe zones and be conscious of what parties are doing around you.
Added a pic that shows some of the slope prior to slide.

FORECASTER COMMENTS (Trent Meisenheimer): I was in the area watching the slope as a group of three inched out into more northerly terrain. I could not see Nick (who reported this slide) from where I was. I saw the slope avalanche and immediately notified the authorities as there were many tracks and people in the area. Luckily nobody was caught in this avalanche. It's tough to know if the party above / or the party at the toe of the debris triggered this avalanche.
In the first photo: Notice all the tracks that cut underneath this avalanche. This is a very popular traverse, and this avalanche covered these tracks with 10' + of debris.
