Trip Planning for Southern Gallatin

Natural avalanche spotted from the air on Red Mountain, just west of Ernest Miller Ridge

We experienced a remarkable number of thunderous collapses throughout the day (I lost count), one of which triggered an avalanche into Specimen Creek while we were in the flats. Photo: R Parsons

From obs on 12/29: "On our way out near the cabin I cut a line close to a creek to see if I could trigger something."

Gusty winds transporting snow in Taylor Fork on Saturday. Triggered a 4-5 inch deep wind slab that propagated about 50 ft at the top of a north east facing slope at 9,500 ft.

Big Sky Ski Patrol triggered this avalanche during mitigation work in The Wave on 11/26/24... "2-3' deep on an ice crust just above the ground with a 2# shot in the Upper rodeo. Volume was limited as most of the snow was loaded just underneath the cornice, but still produced a sizeable size 2... Other paths in the Lenin region ran meaty wind slabs, full track with no significant step downs." Photo: BSSP

From e-mail: "Photo attached from near top of hyalite peak, 11/2. Cracking in recent hard wind slab, I had to really jump hard to make this. Walked on many other hard slabs that were well bonded. Highly variable snowpack. I think you'd be most likely to get into trouble by popping out a small hard slab pocket like this and getting magic carpeted into some thinly covered terrain." Photo: B.

From obs: "1-3 mm faceting in front of the Montage. Clear skys and mid 20 temps"

On October 17, rain turned to snow and blanketed the mountains of southwest Montana with a fresh coat of snow. Photo: Yellowstone Club Webcam
