From obs. 2/26/22: "This is a slide that was triggered today at Mt. Blackmore. Nobody was hurt...”
From email 2/26/22: "Skiing in the Northern Bridgers today, one skier in our party of three triggered an avalanche in October bowl. The sslidewas approximately 40 yds wide and ran around 150 yds. The skier was carried approximately 100 yds, but was not buried and sustained no injuries. Neither of the other members of our party were in the sslidepath when it occurred."

From obs. 2/26/22: "Hey guys wanted to report a few avalanches we set off in the northern bridger range today, while skiing off of Seitz Peak. We skied the couloir (on horrible wind-scoured snow) without incident, then skied out onto the fan. I got a dozen or so turns in when the slope propagated 200’ below me, roughly 400’ wide. I skied off to the side to let it pass and watched it break sympathetically 200’ above my original triggetrigger point8” thick at the thickest point. Overall 600’ wide, 8-18” thick, and ran over 1000 vertical feet. On our way down out of the bowl both my partner and I were able to break off more slabs through remote triggers, 50-100’ away getting them to break 8-12” deep and 100-200’ wide. All the slides broke on a layer of small grain facets in the new snow/old snow interface. We bailed on our other objectives for the day and skinned back out to the sled. Very touchy out there today!"

From obs 2/26/22: "We were stopped on a flat bench on top of a steep rollover... when we heard a whumpf, and then a hard wind slab released on the slope below us and ran into the trees below. We then decided to enter the avalanche at the bottom of the debris to look at the crown, where we observed that the sslabwas about 60cm deep at its deepest, and ran around 50 feet wide, wrapping across a small aaspectchange. We did two ECT tests and observed ppropagationon the layer during isolation in both tests... We identified a P hard wwind slaboverlaying a 3 cm deep layer of 1F hard facets. The layer below the avalanche interface was F hard facets. After this result, we dialed back our ski plans for the day." Photo: M. Beck
