On the headwall of the Second Yellow Mule, we saw two recent wind slab avalanches. These were small (R1 D1), immediately below the ridge, and likely broke late last night or this morning. Photo: GNFAC

Strong winds blew all day from the SW, sustaining 30mph at ridgelines. Snow was actively transported all day by winds, and plumes were visible on far away ridgelines and summits. Photo: GNFAC

Small soft slab avalanches near Fairy Lake
Toured up around fairy lake today, winds were ripping all day. Saw several d1 soft slabs in upper elevation terrain, many of them running quite far. We opted ski a lower elevation zone and were surprised to find a soft slab (d1/r1) that ran on an east facing slope at about 7500’ and about 500-600 ft below the ridge line on a slope just over 30 degrees.
Cooke City Avalanches
Saw a number of slides today, as to be expected. All the large ones I noticed were north facing. Also, the dirty snow was so odd to see mid winter. It was brown all over the sled zone.
N face of crown butte, looks like it slid before the dirt event (we think the end of the storm yesterday/ or last night must have been dirty snow?). It was extremely deep and terrible vis yesterday, but blower snow. Not the case today with how warm it got.
This is the N side of scotch bonnet, looks like a big break, didn’t get any closer than this however.
Also saw some decent sized slides on the N side of Henderson, but was too far away to get photos.
Just a little wind load cornice break, but it broke while I was coming down that track to the right.
