shooting cracks in the top 4 to 5 inches of new snow in middle basin

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.

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)."
