Bridger Bowl ski patrol reported five natural wet avalanches that occurred in closed terrain. Many were D1-D1.5, one was R2-D2.

A small natural out of the sunnyside of lower Job 3... at 12.30pm.

[around 1:30pm] a small natural (similar in size to the Job 3 release) ran out of Baldwins Bad Idea Butress and put a very small pile on the North Bowl Road.

A small natural ran out of LeMons around 3pm, and the High-T fence between tight squeeze and never never land cliffs was taken 300ft downhill by a 2' deep wet slide release around that time.

A larger natural R2D2 ran out of Catch and Release late afternoon that left a medium sized pile of debris in Bridger Gully above the Bears.

Notes

On March 24, 2022 a group of six skiers descended the west side of Woody Ridge near an area locally
known as KNB's. Approximately a third of the way down the slope the group triggered an avalanche that
crossed three gullies, broke 1-3 feet deep, 275 feet wide (measured on GoogleEarth) and ran 700 feet
vertical. Five skiers were stopped, watching one descend the slope. Three of the stopped skiers were in a
row of dense trees directly above and adjacent to where the slide broke and two were stopped a few
feet below the trees. The avalanche caught the skier and two members of the group who were stopped
downhill of the trees. One skier was pinned against a tree and the avalanche passed him. The second
skier slid into a tree sustaining multiple suspected rib fractures. The third, who was actively skiing, was
caught, carried and partially buried with just his arm sticking out of the snow, 500 vertical feet below the
avalanche crown. All three captured skiers successfully deployed their airbags.

The three remaining members of the group switched their avalanche transceivers to search and located
all three victims, and unburied the partially buried skier within five minutes. All members of the group
had formal avalanche training: Avalanche Level 1 and 2 up to a Pro Level 2. All members of the group had
avalanche transceivers, shovels, probes and airbags. The group performed field first aid and
self-evacuated to Cooke City.

Notes

Solar input triggered small cornice collapse while booting up fat maid that ran by our group, but did not trigger anything from its impact on the slope. We saw many wet avalanches both small and large, mostly loose, but one slab that came down the south east face of Bole after skiing the pinner.
