THIS AVALANCHE ADVISORY EXPIRED ON January 8, 2016 @ 6:36 am
Avalanche Advisory published on January 7, 2016 @ 6:36 am
Issued by -
bottom line

The overall avalanche danger is LOW. Human triggered avalanches are unlikely. Except for elevations above 7500 feet where wind slabs still exist on southwest through east aspects, the avalanche danger is MODERATE. If traveling in high elevations today, evaluate the snow and terrain carefully and avoid areas of concern.

How to read the advisory


  • Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Wind slabs are still present in elevations above 7500 feet in specific terrain features. If you are in steep terrain be on the look out for these slabs. Stiff, pillow shaped deposits should be avoided when in high elevation consequential terrain. Triggering a wind slab in sheltered terrain and on all lower elevation slopes is unlikely.

advisory discussion

We know you all have been getting out the past few weeks...we would love to here about it! Use our sweet OBSERVATION page to drop us a line. It is super easy, and you don't need to use any special jargon or worry about submitting pit profiles (you can if you want). Any information and pictures about avalanche activity you saw, or the fact that you didn't see any avalanche activity, while you were out in the backcountry would be great. We need you!

recent observations

Snowmobiles are getting into non-motorized areas...check the Winter Travel Map (East side/ West side) on closures before you head out. Remember that the Granite Mt. closure goes into effect on 1/15 also, please respect non-motorized closures in the area. It is your responsibility to know the motorized/non-motorized boundaries.

Skiers and riders are getting into some of our more consequential terrain...make sure that you have an escape route planned if something goes wrong:

-Know how to perform slope cuts on skis, snowboard, and/or snowmobile and remember that this technique only works for softer slabs. As slabs harden, they will allow you to get further out before being triggered. If you were to trigger an avalanche, have an escape route.

-Use good travel practices when you are in avalanche terrain. Travel one at a time while skinning, skiing, and riding avalanche terrain.

-Make sure that everyone in your group is carrying avalanche rescue gear (beacon, probe, shovel) and knows how to use it. This is a great time to be practicing with your beacon before the next big dump.
