3/23/2014 UPDATE: NWAC report on this incident reads: Around 4:45 PM on Saturday afternoon 2 skiers and a dog descending the looker’s left (or skier’s right) avalanche path on the south side of Granite Mt (visible from I-90) triggered a slab avalanche that stepped down to a deeper slab. Upon review of crown photos (below) and conversations with local avalanche professionals from Snoqualmie Pass it seems most likely that the initial slab failure on this cross loaded path included the Wed/Thu storm snow and the second slab of similar depth included last Sun/Mon storm snow with the bonds between these layers weakened by strong solar input and potential melt water in the upper snowpack during the afternoon. The best estimate right now is that both slabs were at least 1 foot in depth. The skier caught and eventually killed in the slide left the ridgeline at about 5200 ft in elevation and skied onto a steep (40+ degrees) slope. The avalanche became a large and destructive wet slab funneling down to around 2300′, entraining increasingly saturated snow lower in the avalanche path and at times gouging to the ground. Initial size estimates are at least D3/R3. The other person was in a safe zone and not affected. The skier who was caught was buried under 20 feet of debris but was recovered Sunday morning by local search and rescue efforts. Another party of two lower on Granite was not caught and aided in the preliminary search efforts. We don’t believe the upper snowpack structure that led to this accident is common throughout the west slopes. However, we are increasingly concerned about wet snow avalanches on Monday, including those in isolated areas that could lead to wet slab avalanches. ORIGINAL POST 3/22/2014: We heard an avalanche close to home on Granite Mountain off i90 Exit 47 claimed the life of a backcountry skier yesterday. Our hearts go out to the family and friends of the lost skier. The avalanche struck on the face of Granite, looker’s left – we were able to see debris all the way down to the waterfall. This is the same danger zone that released last year in early April and claimed the life of a climber. It’s a sad reminder to us all that conditions, while they look nice under the sun, can still be dangerous given the recent snowfall and warming temperatures.
