Avalanche problems
Avalanche Summary
You could trigger avalanches where you find cohesive slabs of snow sitting on top of weak snow. The most dangerous slopes face northeast through east. Avalanches are more likely in wind-drifted terrain features at upper elevations. Drifted snow often feels stiff and may crack under your weight. Cracking and collapsing in the snow are signs of instability and an indication to move to slopes less than about 35 degrees in steepness.
Moderate winds are drifting snow at upper elevations. Anticipate small isolated and reactive wind slabs in recently drifted snow on east to south through southwest slopes.
On Tuesday, January 7, a backcountry skier was caught and killed in an avalanche on Red Mountain Number 3, near Red Mountain Pass. The avalanche was triggered on a wind-drifted northwest-facing slope near treeline. Our deepest condolences to the deceased skier's family, friends, and community.
