Natural Avalanche Bridger Bowl

On 20241107 I observed a small natural avalanche from the top of the PK lift at Bridger Bowl. The slide occurred near the Slushman’s lift on a NNE aspect. It started as a small release in the upper start zone and entrained much of the snow in the couloir down to the ground. L-N-D1.5- G.
Avalanche occurred after the start zone had come into the sun for a few minutes. The rest of the path was in the shade.
Wind speed at 11am 24mph gusting to 28mph on Bridger Ridge. Sky Clear. Temp 26F.
It was a relatively small slide but had enough power to carry a skier or rider through some very nasty terrain. Similar aspect and elevation to the Super Couloir slide.

Notes
From IG Message: “Hey guys - my partner broke off a small avalanche in super couloir today… broke full depth across half the couloir, 2-3’ deep/20’ wide and looked like it ran around 500’. No one was caught. He might message you with pictures too but here’s a video from the top”
From IG Message: “Skier triggered Pocket in super couloir. Wasn't very unexpected, the skiers left side felt a little slabbier than the skiers right and tried to stay off it but got blinded by a sick face shot. Triggered going over a sharky rock spot, not very fast moving and easy to ski out of. Snow depth was 2-2.5 feet”
