From IG messages on June 1 2024: "there were two riders and a dog on the slope. One rider was partially caught and rode out when everything stopped moving.... Happened about 3pm today within the first 20 riders. Started with a small slide and propagated much larger when it got closer to the rocks." Photo: L. Durkin

Human triggered R3 D3 Gardiner Headwall

Snowmobiling

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.

The dog was very afraid and got stuck at the crown and rocks on the lookers left.

Wet snow avys, all over East side of Bridgers

Date

I'm sure you don't need me to tell you there are wet slides all along the east side of the Bridgers,  but here I am telling you anyway.

I was riding my ATV up Olson Creek and took a few pictures from the top, but I was pretty far away for a cell phone...

If you want them, I'll send them over.

Spring Conditions in Beehive Basin

Date
Activity
Snowboarding

Toured into Beehive Basin today. The added snow from the storm this week made quite a difference in coverage (which was already still really good) and it looks like the middle of winter up there. Temps were warm and the snowpack felt homogenous and stable. Planned to ski peak 10602 but we noticed some wind loading and weather coming in so we toured up and around climbers left of the prow and skied down the climbers right side of it. Skinning in we saw a lot of wet loose avalanche debris and a couple slides that looked like they slid a couple days ago from the last storm. We heard multiple slides coming off of rocks and watched a cornice break off climbers left of 4th of July Couloir. We also saw some wet loose debris that slid on 10602 on our way out of the basin. By 10am it was very warm and the snow was wet, sticky and heavy.

Notes

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."
