Previous avalanche advisories HERE


Natural and human-triggered avalanches will be unlikely today. While generally safe avalanche conditions exist, watch for unstable snow on isolated or extreme terrain features. However, if the sun pops out and temperatures rise, isolated small wet loose and wet slab avalanches may be possible on steep E to W aspects at  mid and upper elevations and all aspects at lower elevations.

Cornices are still large and unpredictable, give them a wide berth.

In surveys of Upper Willow Creek, Independence Mine Bowl, Archangel, Reed Lakes drainage this week, only one natural, large wet loose avalanche (possible wet slab) was observed. This avalanche occurred on a west aspect on Across Motherlode run at 4000’ and is believed to have occurred Tuesday. ~1.5” of new snow fell above 2000’ on Tuesday afternoon, with rain falling below 2000’.  Several very small wet loose point releases were observed on southerly aspects Tuesday afternoon.

All aspects at lower elevations and southerly aspects at mid and upper elevations are rapidly melting out with bare ground exposed across Hatcher Pass. Great corn harvesting is possible, with the right timing, on E to SW aspects.  6” deep near surface facets exist on due north aspects at upper elevations.  While most due north aspects at upper elevations have been heavily skied near the road, especially in Independence Mine Bowl, if you are willing to travel further out, excellent skiing and riding awaits on north aspects.
