Notes

From obs 11/6/24: "Saw debris from several small natural avalanches below the ridge on an east aspect south of saddle peak while driving up to bridger. Most looked like point releases but there was one that might have been a small slab. Unsure because the light wasn't right to tell if there was a crown.

We stayed low but found a pretty uniform snowpack other than a couple of spots with sun crusts.

There was also tons of snow blowing over the ridge when we left around 3pm."

From obs: "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... 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." Photo: P. Crockard

    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.
