Bottom Line: Spring weather can be highly variable and create a mix of avalanche problems to watch out for. Snow conditions and snow stability can change drastically from day to day or hour to hour. Anticipate rapid change and plan accordingly. Plenty of snowfall over the winter with more spring snow to come makes avalanches possible into summer.

  • "At approximately 15:40 a D3 avalanche on the Gardiner headwall broke.  It was triggered by a snowboarder and his dog.  The run had already been tracked by skis and snow machines but the trigger point was slightly farther skier right and appeared to trigger a convex wind slab. Several skiers, boarders, and riders were in the area but there were no burials or injuries."

  • From obs 5/23/24: "Toured to the top of PK during today’s storm. Snow was very wet and heavy. We saw no other slides or signs of instability on the way up. Coming down skiers right of flippers, all 3 of us caused small slides and cracking within the new snow. I triggered the largest slide, which was 6-8” deep and 12’ wide." Photo: T. Jordan

  • From email 5/16/24: "I saw the photo of the fisher peak avalanche on the website. Figured I could fill in the blanks. Not a natural slide, snowmobile triggered.

    At approximately 12:15pm last Saturday I was climbing above fisher bench and unintentionally set off a slab avalanche on fisher peak. I was jumping the cornice at the ridge and had a massive slope collapse, followed by shooting cracks and propagation downslope. I was able to wheelie through the crown and sidehill above the slide away from the debris area.

    5 minutes before my climb, another snowmobiler put a high mark 60 ft away from where I climbed with no results. There were numerous tracks on the slope prior to this avalanche, I found the weak spot. My riding partner was watching me from a safe zone further south, as we knew there was new snow instabilities to watch out for, at a minimum.

    We rode all day Friday without any obvious instabilities on similar slopes. We didn’t see the sheep mountain slide Friday morning. I took some pictures of the slide right after it happened. See attached…"

  • From obs 5/12/24: "Saw a few slides that look like they propagated across the layer of new snow from the last storm (as opposed to the characteristic spring wet snow point releases). The largest was the previously reported one from Sheep... We also saw a similar slide on a N/NW aspect of Mt Zimmer (pictured). Hard to say from a distance when these broke, but the one on Mt Zimmer looked the most recent." Photo: A. Kautzer

The largest was the previously reported one from Sheep. On the way out we saw a smaller slide farther south along the same ridge that looked like it broke on the new snow interface, both NE aspects (pictured)."

  • From obs 5/2/24: "Wind load on old crust, probably from Wednesday."

  • From email 5/1/24: "Hi crew. I triggered a soft slab avalanche on the North side of Sheep Mountain today. D1.5 200’ wide ran 200’.  Crown was 6-12’’ deep. I was able to ride out of it and anchor in a safe spot. 

    It broke on our 7th lap and we had seen no signs of instability prior to the avalanche but wind loading was occurring and obvious. The avalanche broke and on a dirty crust that formed during a rain event last week."

  • On 4/26/24 large natural wet slabs were seen running on Wall Mountain near Silver Gate. An observer from Beartooth Powder Guides sent us a video of them happening at 3pm while it was 43 degrees F.

  • We triggered this small avalanche on a steep windloaded rollover on an otherwise mellow slope. This avalanche was 15-20' wide, 8" deep, and ran for about 30-40 vertical feet. The skier easily skied away from the slide and was not caught. Photo: GNFAC

  • We saw no new deep slab avalanches in Cooke City since Alex was there last week. Unfortunately, if you triggered one, it would be no less deadly. This was a large deep slab avalanche on Sheep Mountain. Photo: GNFAC

  • On 3/10/24 Low on Daisy Road along the steep creek walls we saw three recent 2' deep avalanches. each 70-100' wide. HS-R4-D2-O. This one looked within the last day or two and the other two were maybe 3-4 days old. Triggers unknown, there were various ages of sled/snowbike tracks nearby. Photo: GNFAC
