Northern Wallowas
Avalanche danger
Highlights
It is unlikely to trigger a large avalanche today. Colder temperatures and increasing cloud cover will likely minimize any wet loose avalanche activity today. Hard and frozen snow surfaces may make travel difficult at mid and upper elevations. Avoid overhanging cornices along ridgelines.
Today's forecast is sponsored by Anthony Lakes Mountain Resort.
Avalanche Discussion
Generally Stable Conditions:
Low avalanche hazard exists today at all elevations. The ridge of high pressure that has been dominating our region has resulted in a strong temperature inversion. Throughout the week, lower elevations have been under a thick blanket of valley fog with colder temperatures down low and warmer temperatures at higher elevations. Want to escape the gloom of the inversion? Gain some elevation. Colder air is entering the region from the north, as a weak weather system will bring some high clouds to the region today. This should limit any concerns of wet loose avalanche activity.
Travel may be difficult on frozen/refrozen surfaces.
Be prepared for challenging travel through firm snow. Consider carrying an ice axe, ski/boot crampons, and know how to self-arrest. Not into riding firm snow? There are still slopes facing due North that have been sheltered from the wind that hold soft, dry snow.
Be aware that colder temperatures and cloudier skies through the weekend will keep many surfaces firm and slick- especially on previously warmed slopes. Exposed upper elevations hold a mixed bag of surface crusts, soft but weak surface snow, and wind-stiffened snow that is unlikely to be reactive as a wind slab. Many ridgelines contain large cornices; Be conservative around these.
The current snow surface will become a concern once buried:
Clear, cold nights and a strong temperature gradient in the upper snowpack have weakened (or faceted) the upper six inches of the snow surface on mid- and upper-elevation Northwest, North, and East aspects. On aspects that face towards the sun (Southeast - South - Southwest - West), a melt freeze crust exists.
All of the lucky charms are in play here as winter enthusiasts continue to eagerly look to the long-range weather forecast with glimmers of hope. We will eventually get a pattern change that brings more snow. Riding conditions will improve, but avalanche hazard will rise once we put a slab of cohesive snow on the current surface.
Deeper in the snowpack: Concerning snowpack structure exists in the Elkhorns and outlying areas of the Wallowas.
Specifically, forecasters and observers have been tracking weak snow around the 1/3 crust in Elkhorns. This can be found one to two feet from the snow surface. In many places in the Wallowas, the 1/3 interface is marked by a layer of graupel snow.
The concerning structure in the Wallowas exists where:
1.) Shallower total snowpack depths (less than 4 feet) exist AND
2.) The 12/18 crust near the ground is a series of breakable crusts with weak/faceted snow in between the crusts.
There will be a tipping point for these layers- at some point. How it will unfold is uncertain. Stay tuned and hold steady.
