Notes

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 trigger point, 12-18” 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!"
