We saw this natural avalanche on 3/19/22 appeared to be within 24 hours old and triggered by cornice fall that broke out a slab below. Northeast aspect at 8,800' on Lionhead Ridge. Photo: GNFAC

From obs. 3/18/22: "Slide which looks to be triggered by a skier or snowboarder, on an east facing slope of Mount Abundance. Slide pictured was estimated 100 feet wide, and 12" deep, and ran a couple hundred feet. If you look to the right, on the slope, another crown can be seen, which was equal size to this one."

 "...cornice triggered slide on saddle today. Broke a couple of feet deep, and I couldn’t get too close to the crown but it seemed to have initially broken in the new snow and then stepped down to a PWL below the recent crust...propagated maybe 130ft wide and ran all the way over the saddle cliff to the flats."

We observed a natural avalanche on Saddle Peak on our drive home today. The Bridger Range received 7" of heavy snow equal to 1" of snow water equivalent in the last 24 hours. During the day we saw heavy wind-loading occurring on the high peaks of the range including Saddle. Photo: GNFAC

From IG: "Avalanche in the crazies that caught and carried me today. There were quite a few cars at the trailhead so I thought I’d share so maybe more people knew what the crazies snowpack is like.

Hard wind slab on a NE aspect at 8000ft. The whole seam was about 300feet wide and the toe was maybe 100 feet below the crown at the furthest. Collapsed on buried surface hoar on top of a freeze crust."
