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

Plenty of wind slabs ranging in size on Lionhead ridge and on surrounding slopes. Photo: Riley

This slab from my ski cut was about 20” deep and 60’ wide. It’s NE facing so pretty wind blown. Photo: S Budac

Alex documenting the stratigraphy on a W aspect at 8850' near the Wilderness Boundary

On a north aspect at 9200 ft, there were 1mm facets chained together almost 10mm long.

A layer of nsf's and surface hoar was failing ~10 inches deep producing easy ECTP's

A layer of nsf's and surface hoar was failing ~10 inches deep and causing shooting cracks

Lots of wind transport filling in the skin track between laps and creating light reactive slabs ~5” deep in places (see photo) primarily out of the west but generally inconsistent in direction. Photo: E Kiesz

Buried SH below the 2/1 storm. 1-2cm thick layer buried approximately 20cm deep below F precip particles. Photo: M Zia 

Skied north of Cooke City. Lots of cracking and small slabs on pillows. Observed one small wind slab on NW facing slope 9200 ft. Photo: BPG
