In sintesi

A likely overnight hard freeze in all zones has decreased the avalanche danger.  Expect wet snow avalanches on steep slopes on aspects with solar heating.  This hazard changes rapidly, so start early and be prepared to spin on your objective if you miss your opportunity.

    You can find fun corn riding when the sun softens the top 1" or so above a frozen crust.  When the sun bakes it to a gloppy 2-4" or ankle-deep mush, natural or human-triggered wet loose are possible.  A few inches of cold snow still exists above a rain crust on shaded aspects up to 8000'.  

    If you see rollerballs or pinwheels, or punch through the top supportable snow, move to non-avalanche terrain or shady aspects.

Avalanche Discussion

Observations:  Yesterday in the N Wallowas, binoculars were the tool of choice to observe this large or very large slab avalanche from the past week.  There were also fewer and smaller cornices than expected on Chief Joseph and Wing Ridge.  

Skiers from this week in the Halfway and Burger Butte areas of the S Wallowas found soft slabs (12-18") and small to large wet loose avalanches that naturally released from Sunday/Monday's rain-on-snow event.  Significantly, there has been only 1 crown reported in the 3-4' range or very large (D3+) debris piles that would indicate a persistent slab avalanche on our January facets layer.  As a result of this general lack of activity under major loading, we have decided to move our persistent slab problem to "dormant" or unlisted.  

What to do:  A wide mix of surface conditions and riding qualities exists in all zones.  Avoiding the avalanche problem and seeking the best snow quality are often related.  Timing and aspect choice are your top tools today, so plan your day so you can move off of and out from under steep sunny terrain by early afternoon.

On Friday 2/28, there was a snowmobiler fatality in the Methow area  of the North Cascades.  Our deepest condolences to the family, friends, and community.
