Points saillants

Today it will be possible to trigger a wind slab avalanche.  Fresh wind slabs will continue to grow especially near and above the treeline.  Look for signs such as shooting cracks, collapsing of the snowpack, and poor bonding to steer you towards lower-angle terrain.

    Wind slabs will continue to develop today and will be the most reactive around ridgelines and steep rolls in more wind-exposed terrain.  These slabs could be 1-2' thick, and large enough to take you for a ride.  Look for visual clues such as textured snow surfaces, dune-like formations, and drifts.  Small test slopes can help you determine the sensitivity to human triggers, especially if you observe shooting cracks.  It's wise to avoid traveling uphill or downhill on suspect slopes, as even a small avalanche could take you for a ride.

Avalanche Discussion

Snowpack Observations:  It's a wise decision to measure snow depths as you're getting out, identify crusts, and look for strong snow over weak snow.  You'll only be able to gather this information if you slow down, pull out your probe, and shovel, or at least dig a hasty pit with your hand or snowmobile track.  Without taking some time to determine what's going on beneath you, how will you ever know if the slopes you are traveling on, or underneath is safe?  Please also send us your observations and use #wallowaavalanchecenter.   Here is a recent observation from the Elkhorns by Pro Observer Karen Morse.  

Scholarships:  Through the support of local businesses including Winding Waters River Expeditions, Eagle Cap Mountain Guides, The Avalanche Hour Podcast and the WAC we are currently offering submissions for 2 Motorized and 2 Non-Motorized scholarships.  These scholarships are to honor our avalanche forecasters Kip Rand and Nick Burks.  Submissions are due by December 15th, and if you've already signed up for a course with the WAC and receive a scholarship we'll refund your money.  You can apply the scholarship to an AIARE 1, 2, or rescue course offered by the WAC this winter.  Kip Rand Application Nick Burks Motorized Application
