The avalanche danger in the west central Montana backcountry is moderate. Evaluate snow and terrain carefully.

Good Morning. This is Travis Craft with the West Central Montana Avalanche Center advisory on Saturday, March 6, 2021. This advisory is sponsored by the Trail Head. This advisory does not apply to operating ski areas and expires at midnight tonight. The USDA Forest Service is solely responsible for its content.

Weather and Snowpack

Temperatures range from 22 to 38 degrees this morning. Temperatures froze overnight in all locations except in the Rattlesnake at higher elevations. This will lock up low elevation and mid-elevation snowpacks. Winds are predicted to be gusty into the 20’s today out of the SW. Winds will help keep the snowpack cool. Cloud cover is expected with the front moving in today. Yesterday, we found N slopes above 7000 ft to be dry. Expect to find a melt-freeze crust today on all other aspects as you travel, getting thinner as you gain elevation. Facets failed in tests above 7000 ft in the Central Bitterroot. Rollerballs were observed from Lost Trail Pass to the Rattlesnake on multiple aspects except for true North. In Lost Horse, we observed several Glide avalanches that failed in the previous days. The Rattlesnake pit tests show the snowpack is gaining strength.

Today will have variable conditions. The avalanche danger is MODERATE. Be mindful of changing conditions as you change aspect and gain elevation. Avoid traveling under glide cracks. Pay attention to the snow surface. Is it wet or dry? How thick is the crust? Investigate layers you find in the snow and see if they are reactive in pit tests. Look for rollerballs and move to a different aspect if you see them. Be on the lookout for small areas of wind drifted snow on ridges and terrain features.

Bottom Line

Do not let your guard down. Investigate the snowpack today and see how it changes with aspect and elevation. Choose slopes less than 30 degrees. The persistent weak layers are gaining strength but cannot be ruled out. Seek shaded slopes that are low angle.

Carry a beacon, shovel, and probe. Reassess conditions throughout the day and stay alert for signs of instability. Dig pits. Look for red flags.
