From IG messages on June 1 2024: "there were two riders and a dog on the slope. One rider was partially caught and rode out when everything stopped moving. The dog was very afraid and got stuck at the crown and rocks on the lookers left. Happened about 3pm today within the first 20 riders. Started with a small slide and propagated much larger when it got closer to the rocks."
From antoher ob. "At approximately 15:40 a D3 avalanche on the Gardiner headwall broke. It was triggered by a snowboarder and his dog. The run had already been tracked by skis and snow machines but the trigger point was slightly farther skier right and appeared to trigger a convex wind slab. Several skiers, boarders, and riders were in the area but there were no burials or injuries"
