The episode as NWS SLC wrote it up.
A 31-year-old snowmobiler died when he triggered an avalanche on the east side of Mt. Nebo in Santaquin Canyon. The avalanche was half a mile long and a quarter mile wide. The avalanche was set off when the snowmobiler undercut the snow bank just under the peak, then it all just fell on top of him. It took rescue worker 2 hours to reach the scene, where he was pronounced dead.
1 avalanche. Local standard time, as filed.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
