Rest in Peace, fellow.
Be careful out there.
On Friday the visibility on that ridge dropped down to nothing. Skiing down was a slow cautious affair; when all is white, it is impossible to tell if the slope is up, down or even; despite the fact that I have been out there literally hundreds of times. Saturday improved, but Sunday dropped back to zero. The visibility is worse there than in the area due to the funnelling of clouds through the lowest gap between 9,000 Shuksan and 10,000 Baker. Even a few hundred yards can be a big difference there.
So, the stage was set for a non-treewell NARSID (Non Avalanche Related Snow Immersion Death). While that has not been reported, it has all the classic symptoms. Go to http://treewelldeepsnowsafety.com for more education on these types of fatalities.
