Trip Planning for Southern Gallatin

This wet loose avalanche is a great example of where they often occur. Rocks absorb extra heat from the sun and can quickly melt and destabilize the snow. Either move under areas like this early in the morning (as we did), or if you have to travel under them later in the day, move quickly.

I noticed a couple of wet slides that came off Electric and it’s sun-ridge today. Photo: Anonymous

Understanding Avalanche Safety Preparedness – 5-Minute Survey for Motorized Users

We need your input! Eastern Oregon University is conducting a survey to better understand avalanche safety preparedness among motorized backcountry users like you. Your feedback will help us learn more about who is purchasing and practicing with avalanche rescue gear (beacon, probe, shovel) and participating in avalanche education—and why some riders aren’t.  The survey is confidential and anonymous.  

Your feedback is invaluable in improving avalanche education and awareness. Please take a moment to share your experience and help us make a difference.

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. VandenBos

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