Recent avalanches noted on the NE-E aprons on cedar mountain. SS-N-R2-3-D2-I These appeared to have possibly happened during the last storm cycle and looked to be isolated to layers within the new old snow interface. I also noted similar activity on the same aspects on the adjacent ridge during our approach.

I skied forward maybe 5 feet and broke off a wind slab around 20 feet wide and five feet below me. Shifting my weight right after that the snow below me also broke and slid away. Photo: Anonymous

On Jan 27 we saw  a cornice fall on a very big steep slope up Republic Creek which did not trigger anything large or deeper, but entrained some snow and ran over a thousand feet vertical. Photo: GNFAC

On Jan 27 We saw one old, but very large persistent slab avalanche further up Republic Creek (pictured). It was on similar aspect and elevation as a somewhat more recent persistent slab in nearby Hayden Creek, North-northeast, 10,000'. It appeared to be 6'+ deep and 500'+ wide. The bed surface and crown had been partially drifted in, so it seemed it was probably at least a week old...? Photo: GNFAC

In the Playground area of the Bridger Range, strong winds rapidly built wind slabs up to 25 cm deep around treeline. Skiers experienced a few cracks in this wind slab, propagating 2 or 3 meters from our ski tips. Photo: N. deLeeuw

Skiers triggered a small wind slab avalanche while skinning near the top of Pair Of Chutes in the Playground. The slab was about 1 foot thick, fist hardness, propagated 20 feet wide and ran 50 feet before breaking up and arresting. Photo: J. Taylor

On January 26 we saw a handful (4-6?) of old wind slab avalanches of various ages. The most recent and largest appearing, but still not very fresh, was on the north side of Scotch Bonnet (attached photo). Most were D1-D1.5, the slide pictured was D1.5-2. Photo: GNFAC

While touring today, we saw a deep slab avalanche at the southern end of the Hayden Creek drainage. NE aspect. It seemed to be recent, likely in the last day or so. Photo: N Mattes

Very touchy storm slabs formed throughout the day. 6-8” deep by 3pm. low density snow/slab but very fast moving.Photo: R Griffiths

Jan 24, Buck Ridge... We dug on an E facing slope at 9,400'. Snow depth was 155cm (5 feet) and we had an ECTN12 on the surface hoar layer 10" down. Photo GNFAC

Winds have worked over many slopes near the Throne. We found some slopes stripped nearly to dirt with the snow blown off to who knows where, and others had wind-sculpted sastrugi. Trees were broken off, and debris littered the snow surface. Photo: GNFAC

Today, we traveled into the Maid of the Mist basin and up and along the Palace Butte ridgeline.  Although temperatures have warmed up significantly since the weekend, strong winds kept conditions frigid. Winds blew plumes of snow off the high peaks and at ridgelines, gusting 50-60 mph. Photo: GNFAC
