Lo esencial

Significant new snow and strong winds have created unstable snow conditions.  Wind-drifted snow will remain sensitive to the weight of a rider, near ridgelines, below cliffs, and open terrain features.  Utilize sheltered terrain and lower-angle slopes to decrease your exposure.  

Avalanche danger has been rated Low, below treeline, due to a lack of snow.

    We've just received significant snowfall, along with strong winds.  These wind slabs may rest over slick crusts formed in mid-December. If an avalanche breaks down to these crusts, they could be larger than expected, potentially greater than 2' deep.  Low-angle routes, wind-scoured slopes, or sheltered terrain often provide safer travel options. 

    Just because you aren't seeing natural avalanche activity doesn't mean the danger doesn't exist.  Visual clues such as cracking, dune-like formations, and a textured snow surface all point towards a wind slab.  Reduce your risk by avoiding steep terrain on wind-loaded slopes below ridgelines and features ending in terrain traps. 

    This is a good reminder from our neighbors at the Sawtooth Avalanche Center of how, even during times of low snow coverage, avalanches can catch us off guard.

Avalanche Discussion

Extreme Weather:  Although clear skies and sunshine will prevail today, don't forget the weather we've just experienced.  The recent wind and heavy snowfall have created sensitive avalanche conditions.  Many steep slopes are primed and waiting for a human to tip the balance.  Just because you aren't seeing natural avalanche activity doesn't mean the danger doesn't exist.    

Mid-December Crust:  All of the new snow we are receiving is sitting on top of a very firm crust that formed in mid-December.  The new snow will need time to bond to this slick surface.  Triggering an avalanche on this layer could be very consequential.  You would be hard-pressed to self-arrest on this ice layer, whether on your snowmobile, skis, or on foot.   

Travel Advice: Although our enthusiasm for the new snow is high, remember that early-season conditions exist.  Use caution as new snow may be lightly covering rocks, trees, strumps, etc.  If you trigger an avalanche, these obstacles will be trauma boosters.
