Primary Problem: Persistent Weak Layer
Bottom Line: Large avalanches breaking deep in the snowpack on persistent weak layers and wet, loose snow avalanches are possible in the mountains across the advisory area. Lower-angle avalanche terrain and slopes with clean runouts and without terrain traps are the best options if you choose to play the odds. Follow safe travel practices, including traveling one at a time while a partner remains in position for rescue. Get off any steep terrain before the surface snow gets wet in more than the upper few inches. This process will happen faster in lower elevations so ensure safe egress options.

Cabin Creek
Coordinates: 44.8949, -111.2280
Caught: 0 ; Buried: 0

From obs: "We were skiing out of the Cabin Creek cabin over the weekend, mostly in the low angle terrain around Skyline Ridge. Throughout the storm on Saturday and after the clouds cleared on Sunday we experienced consistent whumpfing while breaking trail. Some were larger and some were smaller, usually triggered by the person breaking trail but some of the larger ones were triggered by the second or third skier in the track."

Elevation: 8,200
Aspect: E
Coordinates: 44.9609, -111.1000
Caught: 0 ; Buried: 0

We came across 2 deep slab avalanches near the typical Bacon Rind skin track. I suspect given the amount of snow on the debris, the failed on March 2nd. It is unknown whether they were triggered remotely or failed naturally. The avalanches were as large as they could be given the terrain constraints. Slope angles ranged from 29-33 degrees.

From obs on 03/04/2024: "While traveling to Big Sky from Ennis, I noticed a large avalanche on the east face of Fan Mt.

Crown appears to start at approx. the 9500' elevation with a vertical drop of at least 2000'.  Crown appears to be 200-300 yards wide"

  • The skillet slid sometime recently. Based on the snow on top I'm guessing Thursday-Friday last week (Feb 15-16th), but it could have happened up to a week earlier. Broke ~2 ft deep, 150 ft wide, and it was hard to tell how far it ran, but I'm estimating 200 vertical feet. Photo: GNFAC

  • From email: "A friend and I were riding in lower Tepee today, staying on low angle terrain because of the current avalanche conditions. When side hilling on a 24 degree slope, I saw cracks shoot out approximately 100 feet around me. It was a smaller slope, but things are still pretty sensitive. This was a north facing slope in a valley that shouldn’t have been too wind loaded. " Photo: J. Norlander

The Last Word

The Colorado Avalanche Information Center, the Avalanche Research Program at Simon Fraser University and the U.S. National Science Foundation National Center for Atmospheric Research are conducting research to examine how backcountry recreationists, including skiers, mountain snowmobilers, snowshoers and ice climbers, interpret avalanche forecast information. They aim to better understand how useful different kinds of avalanche forecast information are for trip planning. To participate, take the Colorado Avalanche Information Center survey.
