Points saillants

Another round of snowfall today will require you to use caution while traveling in the mountains.  New snow and 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.

    New snow today has the potential to cover the older wind slab.  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.   You can dig down with your shovel, or use your probe to determine the amount of new snow sitting on top of the mid-December crust.  

    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

Happy Winter Solstice!  Enjoy the shortest day of the year.  

Weekend Weather:  Another round of snowfall with moderate accumulation is expected today.  This new snow will likely be heavier than the snow that fell on Friday, due to an increase in snow levels and temperatures.   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:  WAC Forecaster Caleb Merrill traveled in the Northern Wallowas on 12/20 and found unstable snow conditions.  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.
