From Obs, "Toured wolverine bowl and noticed a couple of large slides near the ridge on NE aspects. The most obvious was this one on the Hourglass that looks like it went in the last week. The trigger could have been part of the massive cornices breaking off." Photo: R. Leslie

From obs. "Around 4 or 5 pm today we rode out of Sheep Creek into the Miller Mountain area. When we looked at Miller there was a large avalanche that appeared to have occurred naturally (to our knowledge). It looked like the crown was 12-24'' and a few hundred feet wide. The debris looked fresh and must have occurred today. Given the depth we assumed it was windslab that had built up sometime in the last few days; however, hard to tell from so far away." Photo: R.

On Buck Ridge today (3/5/23) we found fresh, unstable drifts. This fresh slab was 4-6" deep. Cracking like this is a sign that wind slabs will avalanche on steeper slopes. Photo: GNFAC

"FYI big skier triggered avalanche on the lawn mower slide path on town hill today around 3pm. One skier caught and buried to neck and later airlifted out with leg injury. Our party arrived maybe 45 min after the slide and assisted others who were there." Photo: D. Harnick

"On March 4th around 2:15 PM my partner and I observed a skier (of a separate party that was caught and carried) in a D2 R2 on the Lawnmower in the Absorkas. I believe the slide was released on a buried weak layer (We only observed the crown from a distance). The victim came to a stop approximately 1,200 ft below the start zone and was buried up to his neck. There were multiple tracks on the slope prior to the avalanche. My partner and I skied up to the separate party with the victim approximately 30 minutes after the event." Photo: A. Whitelaw

Walking along Henderson ridge, Doug Chabot touched a cornice with his ski pole and it broke 40 feet wide. Cornices are touchy and need t be given a wide berth. Photo: GNFAC
